    Commonwealth.
    LOWY, J.    At a house party, in the early morning hours of
    October 22, 2016, a series of verbal and physical fights broke
    out between a number of party attendees, including the eighteen
    2
    year old defendant, Kelly D. Ridley, Jr., and the twenty-six
    year old victim, Thomas Russell.   During a brawl between the
    defendant and the victim, the defendant stabbed the victim nine
    times in the torso and leg, ultimately killing him.     Following a
    jury trial, the defendant was convicted of murder in the first
    degree on the theory of extreme atrocity or cruelty.1    Following
    his convictions, the defendant filed a motion for a new trial,
    which was denied.
    In this consolidated appeal, the defendant argues that a
    new trial is required because (1) the judge excluded expert
    testimony on late adolescent brain development; (2) the
    prosecutor misstated the law of voluntary manslaughter during
    closing argument; (3) the judge failed to provide an instruction
    on involuntary manslaughter; and (4) the judge abused his
    discretion in responding to a jury question.   Additionally, the
    defendant contends that, in light of his age at the time of the
    crimes and the current research on late adolescent brain
    development, we should extend the principles underlying Miller
    v. Alabama, 
    567 U.S. 460
     (2012), and its State law counterpart,
    Diatchenko v. District Attorney for the Suffolk Dist., 
    466 Mass. 655
     (2013), S.C., 
    471 Mass. 12
     (2015) (Diatchenko I), and
    conclude that his sentence of life without the possibility of

    and battery by means of a dangerous weapon.
    3
    parole violates art. 26 of the Massachusetts Declaration of
    Rights and the Eighth Amendment to the United States
    Constitution.    Finally, the defendant asks us to exercise our
    authority under G. L. c. 278, § 33E, and reduce his conviction
    of murder in the first degree to murder in the second degree or
    voluntary manslaughter.
    We conclude that there was no reversible error.      After
    thorough review of the record, we further discern no reason to
    exercise our extraordinary authority under G. L. c. 278, § 33E,
    to reduce the verdict to a lesser degree of guilt or order a new
    trial.
    Background.    1.    Trial.   We recite the facts as the jury
    could have found them.
    On the evening of October 21, 2016, the victim and his
    cousin, David Gonsalves, went to a local bar and met up with a
    group of the victim's friends, including Joseph France and
    Magnum Desouza.   Priscilla Coelho, a friend of both the victim
    and the defendant, also was at the bar that night.      She invited
    the victim and his group of friends to a house party hosted by
    the defendant.
    The group proceeded to the defendant's house after the bar
    closed.   A dispute arose in the kitchen shortly after the victim
    arrived at the party, which ultimately caused a disagreement
    between the victim and another party attendee, Ricky Powell.
    4
    This disagreement eventually escalated to a physical altercation
    between the victim and Powell outside in the street in front of
    the house.    A crowd of people followed the two outside to watch
    them fight.
    At some point during the fight between the victim and
    Powell, the defendant attempted to jump into the fray.
    Gonsalves eventually became involved as well, and a physical
    altercation ensued between the defendant and Gonsalves; the two
    wrestled each other on the ground, throwing punches, while
    "talking trash."   France ultimately broke up the fight between
    the victim and Powell, and Desouza separated the defendant and
    Gonsalves.    In doing so, Desouza attempted to calm the defendant
    down, but he appeared "determined."
    After both physical altercations seemingly ended, the
    victim walked up the driveway toward the house.   The defendant
    then "came out of nowhere" and struck the victim on his head or
    upper back with a metal scooter.    The defendant remarked, "How
    do you like that, bitch?"    Upon being struck with the scooter,
    the victim appeared "shocked."    He stumbled a bit, turned
    around, and threw the defendant in the bushes, stating words to
    the effect of, "Go inside little man."    The defendant ran to the
    steps of the house and started shouting that he was going to get
    his gun.   Gonsalves returned the shouting, "calling [the
    5
    defendant's] bluff," and taunting the defendant that he was not
    going to follow through.
    As the victim, Desouza, and Gonsalves walked down the
    driveway to leave, the defendant came out of the house, now
    shirtless, holding a five to six inch bladed knife in his right
    hand.    The defendant began waving the knife around, asking, "Who
    wants it?"   The defendant proceeded to the end of the driveway
    and chased Gonsalves into the middle of the street with the
    knife.   The victim, who had walked farther away at this point,
    turned and ran toward the defendant.   The defendant still was
    holding the knife; the victim was unarmed.    The victim threw a
    punch at the defendant, and a physical fight between the two
    followed.    During this fight, the defendant swung both of his
    fists repeatedly into the victim's midsection, including the
    fist that was holding the knife.    The defendant stabbed the
    victim nine times, striking both the torso and the left leg.
    Michael James, a "father-like figure" to the defendant,2
    attempted to break up the fight by grabbing the defendant, and
    the defendant stabbed James in the stomach.    Once the defendant
    and the victim were separated, the defendant ran inside the
    house.
    2 None of the witnesses at trial knew or testified to the
    precise familial relationship between the defendant and James,
    but defense counsel in closing referred to James as the
    defendant's uncle.
    6
    The victim took a couple steps before falling to the ground
    and exclaiming, "I got stabbed."     Desouza and France came to his
    aid.   The victim's abdomen and pants were covered in blood, and
    there was a hole in his stomach and groin area.      His intestines
    were protruding from his body.     The victim still was awake, with
    his eyes wide open, and he was holding his stomach.      He looked
    France in the eyes, while France held his hand.      France
    attempted to talk to the victim and keep him awake, but the
    victim, struggling to breathe, could not respond.      The victim
    remained conscious for a period of time, but when police and
    paramedics arrived, the victim was unconscious and
    nonresponsive.    The paramedics transported the victim to a
    hospital, where he later died of his stab wounds.     An autopsy
    revealed that all nine stab wounds contributed to his death, but
    two had the potential to be fatal to the exclusion of the
    others.
    At some point before police and paramedics arrived at the
    scene, the defendant fled out the back door of the house.      He
    traveled to a number of locations before eventually being found
    by police the next day while being treated for minor injuries at
    the same hospital where the victim died.
    2.   Prior proceedings.   The defendant was indicted by a
    grand jury on charges of murder in the first degree of the
    victim, assault and battery by means of a dangerous weapon
    7
    (metal scooter) against the victim, and assault and battery by
    means of a dangerous weapon (knife) against James.   Before
    trial, the defendant moved in limine to admit expert testimony
    regarding the general characteristics of adolescent brain
    development.   The judge excluded the testimony, and trial
    commenced in October 2018.
    At trial, the defendant conceded that he stabbed and killed
    the victim,3 but argued that the killing was voluntary
    manslaughter based on heat of passion induced by reasonable
    provocation or sudden combat.   The defendant was found guilty on
    all of the indictments and sentenced to life without the
    possibility of parole on the charge of murder in the first
    degree, as statutorily required, G. L. c. 265, § 2, and to two
    concurrent sentences of from eight to ten years on the charges
    of assault and battery by means of a dangerous weapon.    The
    defendant timely appealed.   Following his conviction, the
    defendant moved for a new trial, arguing that the judge erred in
    responding to a jury question about the Commonwealth's burden of
    proof, that his trial counsel was ineffective in failing to
    object to the judge's response, and that his sentence of life
    without the possibility of parole was unconstitutional.     The
    defendant's motion was denied, and his appeal from the denial of
    3 The defendant also conceded that he was guilty of both
    counts of assault and battery by means of a dangerous weapon.
    8
    his motion for a new trial was consolidated with his direct
    appeal.
    Discussion.    1.   Expert testimony.   Prior to trial, the
    defendant filed a motion in limine to admit expert testimony by
    Dr. Frank DiCataldo on adolescent brain development "to provide
    the jury with some background of the general mental development
    of someone in their late adolescence," to assist them in
    determining whether the defendant possessed the requisite intent
    to commit murder.    In support of his motion, the defendant
    submitted a transcript of DiCataldo's testimony on adolescent
    brain development from another criminal case in which the
    defendant also was eighteen years old at the time of his
    offense.   The Commonwealth moved to exclude the proposed
    testimony on the basis that DiCataldo had not conducted an
    individualized examination of the defendant or a review of his
    records, and that expert testimony regarding the general
    characteristics of adolescent brain development would not assist
    the jury in determining the defendant's guilt.     Following a
    hearing, the judge allowed the Commonwealth's motion to exclude
    the testimony.4
    The defendant argues on appeal that the judge abused his
    discretion in excluding DiCataldo's testimony and that he was
    4 The judge allowed the motion "without prejudice."     The
    defendant did not renew the motion.
    9
    deprived of the right to present a defense under the Sixth and
    Fourteenth Amendments to the United States Constitution and art.
    12 of the Massachusetts Declaration of Rights.   We conclude that
    the judge did not err in excluding the proposed expert
    testimony.
    Generally, expert testimony may be admissible whenever "the
    expert's scientific, technical, or other specialized knowledge
    will help the trier of fact to understand the evidence or to
    determine a fact in issue."5   Mass. G. Evid. § 702(a) (2022).
    5 To the extent that we have at times stated that this
    standard requires that the expert testimony be beyond the common
    knowledge or experience of jurors to be admissible, we clarify
    that the primary focus of admissibility is whether the expert
    testimony will help the trier of fact, even where the subject
    matter of the testimony "may be within the knowledge or common
    experience of the trier of fact." Commonwealth v. Little, 
    453 Mass. 766
    , 768 (2009). Rule 702 of the Federal Rules of
    Evidence similarly uses a "helpfulness standard." See P.C.
    Giannelli, Understanding Evidence 316 (5th ed. 2018)
    (Giannelli). See also Fed. R. Evid. 702(a) (expert testimony
    may be admissible where "the expert's scientific, technical, or
    other specialized knowledge will help the trier of fact to
    understand the evidence or to determine a fact in issue"). This
    standard is a more liberal formulation of the common-law
    standard, which asked whether expert testimony was necessary
    because the subject matter was beyond the ken or comprehension
    of lay persons. Giannelli, supra. Rule 702 of the Federal
    Rules of Evidence rejects the necessity test: "The question
    under Rule 702 is not whether the jurors know something about
    this subject, but whether the expert can expand their
    understanding in a relevant way." Id. at 316 n.9, quoting Coble
    v. State, 
    330 S.W.3d 253
    , 288 (Tex. Crim. App. 2010), cert.
    denied, 
    564 U.S. 1020
     (2011). The same standard applies under
    our common-law rules of evidence.
    10
    See Commonwealth v. Little, 
    453 Mass. 766
    , 768 (2009).      "This
    condition goes primarily to relevance."    Daubert v. Merrell Dow
    Pharms., Inc., 
    509 U.S. 579
    , 591 (1993).    "Evidence is relevant
    if (a) it has any tendency to make a fact more or less probable
    than it would be without the evidence and (b) the fact is of
    consequence in determining the action."    Mass. G. Evid. § 401.
    "Expert testimony which does not relate to any issue in the case
    is not relevant and, ergo, non-helpful" (citation omitted).
    Daubert, 
    supra.
       See Ready, petitioner, 
    63 Mass. App. Ct. 171
    ,
    179 (2005) (expert testimony on sexual interest diagnostic test
    properly excluded where test did not concern issues before
    jury).   "The decision to exclude expert testimony rests in the
    broad discretion of the judge and will not be disturbed unless
    the exercise of that discretion constitutes an abuse of
    discretion or other error of law."   Commonwealth v. Fernandes,
    
    487 Mass. 770
    , 778 (2021), cert. denied, 
    142 S. Ct. 831 (2022)
    ,
    quoting Palandjian v. Foster, 
    446 Mass. 100
    , 104 (2006).
    The defendant contends that we approved of the admission of
    this type of expert testimony on the general principles and
    characteristics of adolescent brain development in Commonwealth
    v. Okoro, 
    471 Mass. 51
    , 66-67 (2015).     We did not; the
    defendant's reliance on Okoro is misplaced.    In Fernandes, we
    emphasized that our conclusion in Okoro hinged on the connection
    made between the expert testimony on adolescent brain
    11
    development and the individual defendant in that case.     See
    Fernandes, 487 Mass. at 781-782 ("The ability of an expert to
    testify with respect to the individual defendant specifically is
    critical").   Specifically, in Okoro, 
    supra at 66
    , the expert
    testified about how the development of adolescent brains "could
    inform an understanding of [the] particular juvenile's capacity
    for impulse control and reasoned decision-making" (emphasis
    added).    To the extent that the expert in Okoro testified in
    general terms about the adolescent brain, he did so to compare
    the defendant's specific condition of "'borderline deficient'
    cognitive functioning" to that of adolescents generally.     
    Id.
     at
    53 & 64 n.21.   Indeed, in Okoro we concluded that, although
    expert testimony specific to the defendant was admissible
    because it offered the jury assistance in determining whether
    the defendant was able to form the requisite intent at the time
    of the incident, "the trial judge was correct to preclude the
    defendant from putting forward evidence that would have
    suggested it was impossible for anyone the defendant's age to
    formulate the necessary intent to commit this crime" because
    "the Legislature has clearly indicated that youth in the
    defendant's age group are considered capable of committing
    murder."   
    Id. at 65
    .   See Commonwealth v. Ogden O., 
    448 Mass. 798
    , 805 n.6 (2007) ("respect for the legislative process means
    that it is not the province of the court to sit and weigh
    12
    conflicting evidence supporting or opposing a legislative
    enactment" [citation omitted]).
    Applying those principles in Fernandes, we held that a
    judge "may allow the introduction of expert testimony solely
    with respect to 'general principles and characteristics of the
    undeveloped adolescent brain' only when it is accompanied by
    other evidence, such as testimony by a different expert, or
    medical or school records, specific to the defendant."
    Fernandes, 487 Mass. at 782.   We explained that, without
    evidence pertaining to the particular defendant, "evidence of
    the 'general principles and characteristics of the undeveloped
    adolescent brain' . . . is inadmissible" because "the expert's
    testimony would present the jury with the impermissible
    situation discussed in Okoro, 471 Mass. at 65-66," namely, by
    allowing the jury to conclude, based on the testimony, that any
    person in the defendant's age group could not form the requisite
    intent for murder.   See Fernandes, supra at 782 & n.10.    Because
    such a conclusion would impermissibly contradict a determination
    already made by the Legislature, the expert testimony would not
    assist the jury in resolving a fact in issue.   Distilled to its
    essence, expert testimony on adolescent brain development in
    general is not helpful because it is not relevant.   While
    arguably probative of intent, it is not material -- whether
    generally a person in the defendant's age group can form the
    13
    requisite intent for murder is not at issue.   The Legislature
    has spoken definitively on the matter.    See G. L. c. 265, § 2.
    Here, the defendant proffered no other evidence specific to
    himself to accompany the proposed expert testimony by DiCataldo
    regarding the general principles and characteristics of late
    adolescent brain development.   The proposed testimony thus was
    inadmissible, and the judge properly excluded it.
    2.   Closing argument.   The defendant next argues that the
    prosecutor misstated the law of voluntary manslaughter during
    closing argument.   Because the defendant did not object, we
    review to determine whether any error created a substantial
    likelihood of a miscarriage of justice.   See Commonwealth v.
    Muller, 
    477 Mass. 415
    , 431 (2017).
    "In closing argument, '[l]awyers shall not and must not
    misstate principles of law.'"   Commonwealth v. Bins, 
    465 Mass. 348
    , 367 (2013), quoting Commonwealth v. Haas, 
    373 Mass. 545
    ,
    557 (1977), S.C., 
    398 Mass. 806
     (1986).   Prosecutors "may,
    however, argue 'forcefully for a conviction based on the
    evidence and on inferences that may reasonably be drawn from the
    evidence.'"   Commonwealth v. Carriere, 
    470 Mass. 1
    , 19 (2014),
    quoting Commonwealth v. Kozec, 
    399 Mass. 514
    , 516 (1987).
    "Remarks made during closing arguments are considered in the
    context of the entire argument, and in light of the judge's
    instructions to the jury and the evidence at trial."   Carriere,
    14
    
    supra,
     quoting Commonwealth v. Viriyahiranpaiboon, 
    412 Mass. 224
    , 231 (1992).
    During closing argument, the prosecutor made the following
    statements, the underlined portions of which the defendant now
    challenges:6
    "And think about it. Reasonable provocation. You get
    punched. To believe that that's reasonable provocation,
    anytime there was a fist fight, you would have the ability
    and the right to eviscerate someone? I suggest not. . . .
    "Respectfully suggest to you that all of this evidence of
    going the opposite direction of Cape Cod Hospital, not
    going to the hospital, going in the opposite direction
    right after the crime, and then not going there for another
    seven hours and then being seen to have superficial
    injuries,[7] that sudden combat, a reasonable person would
    not be overcome to the point of not being able to think by
    being punched. . . .
    "I'm going to ask you to use your common sense, use your
    life experience and consider what would a reasonable person
    feel or do in that situation? A punch, then warranting the
    taking of a life, transporting you to a heat of passion
    where you don't know what you're doing? The evidence shows
    6 The defendant specifically challenges the emphasized
    statements. We place the challenged statements in context, as
    we must. See Carriere, 
    470 Mass. at 19
    .
    7 We do not view the prosecutor's reference to the
    defendant's injuries as "superficial" as a misstatement of law
    that a defendant must be seriously injured to support a verdict
    of voluntary manslaughter. As the defendant argues, "even a
    single blow from the victim can constitute reasonable
    provocation," Commonwealth v. Acevedo, 
    446 Mass. 435
    , 444
    (2006), but the prosecutor here was entitled to argue that the
    evidence that the defendant's injuries were minor suggested the
    blows he sustained would not sufficiently provoke a reasonable
    person in the circumstances, see Commonwealth v. Rembiszewski,
    
    363 Mass. 311
    , 321 (1973) (evidence of scratches on defendant's
    face insufficient for reasonable provocation).
    15
    Mr. Ridley knew what he was doing.    He was murdering Thomas
    Russell." (Emphases added.)
    We have little trouble concluding that the latter two
    statements, viewed in context, were not assertions of law by the
    prosecutor but, rather, were forceful arguments that the
    evidence in this case did not support a verdict of voluntary
    manslaughter based on reasonable provocation or sudden combat.
    See Commonwealth v. Yat Fung Ng, 
    489 Mass. 242
    , 257 (2022),
    S.C., 
    491 Mass. 247
     (2023) ("Reasonable provocation is
    provocation [deemed adequate in law] by the person killed . . .
    that would be likely to produce such a state of passion, anger,
    fear, fright, or nervous excitement in a reasonable person as
    would overwhelm his capacity for reflection or restraint and did
    actually produce such a state of mind in the defendant"
    [citation omitted]); Commonwealth v. Brea, 
    488 Mass. 150
    , 157
    (2021) ("Sudden combat is a form of reasonable provocation.     It
    involves a sudden assault by the person killed . . . and the
    defendant upon each other" [quotations and citations omitted]).
    The first statement, however, is a closer call, and it is
    difficult to discern the statement's meaning.   It is phrased
    broadly enough that it could be interpreted as stating that a
    finding of reasonable provocation is equivalent to a conclusion
    that the killing was justified, which is an incorrect statement
    of law.   See Commonwealth v. Rivera, 
    482 Mass. 259
    , 271 (2019),
    16
    citing Commonwealth v. Glover, 
    459 Mass. 836
    , 842 (2011)
    (justification and mitigation "have distinct meanings in the
    law"; "justification defense . . . could result in acquittal,
    and mitigation defense, such as heat of passion, . . . at best
    yields conviction of lesser offense of voluntary manslaughter").8
    Nevertheless, this statement was isolated.       The jury were told
    on several occasions that the judge provides the instructions of
    law.       And the judge's instructions properly stated the law of
    voluntary manslaughter, including reasonable provocation.       We
    presume that the jury followed these instructions.       See Rivera,
    
    supra.
          We conclude, as a result, that this passing statement
    did not create a substantial likelihood of a miscarriage of
    justice.9
    Legal justification for a killing renders an intentional
    8
    homicide noncriminal. See Commonwealth v. Nardone, 
    406 Mass. 123
    , 130-131 (1989). Examples of legal justification include,
    inter alia, "accident, mistake, self-defense, and defense of
    another." Commonwealth v. McLaughlin, 
    431 Mass. 506
    , 514 n.7
    (2000). The defendant did not assert a justification defense at
    trial.
    As a result, the defendant's claim that his counsel was

    3.   Involuntary manslaughter instruction.    The defendant
    claims that the judge erred in denying his request for an
    instruction on involuntary manslaughter based on the evidence
    that he brought a knife into the situation by carrying it down
    the driveway.   "Involuntary manslaughter is an unlawful homicide
    unintentionally caused by an act which constitutes such a
    disregard of probable harmful consequences to another as to
    amount to wanton or reckless conduct."    Commonwealth v. Lopez,
    
    485 Mass. 471
    , 484 (2020), quoting Commonwealth v. Carrillo, 
    483 Mass. 269

    manslaughter is required where any view of the evidence would
    permit a finding of manslaughter and not murder."    Commonwealth

    Pierce, 
    419 Mass. 28
    , 33 (1994).    "When it is obvious, however,
    that the risk of physical harm to the victim created a plain and
    strong likelihood that death will follow, an instruction on
    involuntary manslaughter is not required."    Moseley, supra,
    quoting Pierce, 
    supra.

    instruction was required, we consider the evidence in a light

    not objected to by trial counsel does not create a substantial
    likelihood of a miscarriage of justice . . . , a claim of
    ineffective assistance of counsel with respect to such error
    will not succeed").
    18
    Here, viewing the evidence in the light most favorable to
    the defendant, the defendant was not entitled to an instruction
    on involuntary manslaughter.   The killing was not the result of
    the defendant merely bringing out the knife and carrying it down
    the driveway.   Rather, the evidence was that the defendant swung
    the knife nine times into the unarmed victim's leg and abdomen.
    The act of doing so clearly created a plain and strong
    likelihood that death would follow.    See Commonwealth v.
    Concepcion, 
    487 Mass. 77
    , 92, cert. denied, 
    142 S. Ct. 408 (2021)
    .   See also Lopez, 485 Mass. at 485 ("Because it is
    obvious that stabbing the victim created a plain and strong
    likelihood that death would follow, an involuntary manslaughter
    instruction was not warranted").   There was no error.
    4.    Response to jury question.   Approximately two and one-
    half hours into deliberations, the jury sent a note to the judge
    with several questions and statements.   Relevant here, one such
    statement asserted:   "Jury in agreement with charge with the
    exception of whether or not Commonwealth has proven without
    reasonable doubt there were mitigating circumstances."   After
    the judge read the jury's note to the prosecutor and defense
    counsel at sidebar, he provided each with a copy of the note and
    ordered a brief recess for both to consider their proposed
    responses.
    19
    When counsel reconvened at sidebar, the judge suggested
    that the relevant statement needed "further clarification"
    because it was "not . . . worded in accordance with the
    [c]ourt's instruction."   Specifically, the judge commented that,
    contrary to the jury's note, the Commonwealth must "prove beyond
    a reasonable doubt that there were no mitigating circumstances.
    Not that there were, [but] that there were no."   See
    Commonwealth v. Acevedo, 
    427 Mass. 714
    , 716 (1998) (correct rule
    is that Commonwealth must prove absence of mitigating
    circumstances).   The prosecutor remarked that the jury had an
    audio recording of the jury instructions with them in the
    deliberation room.   Notably, the jury also were provided an
    outline of the audio recording, which listed the time in the
    recording that each individual instruction could be located.
    The prosecutor proposed that the judge respond to the
    jury's statement by advising the jury of their ability to replay
    the judge's instructions.   Defense counsel agreed, stating, "I
    think that makes some sense to instruct them where to listen,
    and they could listen to it as a group, play it, stop it, play
    it, stop it."   The judge, however, expressed some hesitancy in
    telling the jury where exactly in the recording they should
    begin listening because, in addition to the instruction on
    voluntary manslaughter, other instructions, such as the
    instructions on murder in the first degree, also stated that the
    20
    Commonwealth has the burden to prove that there were no
    mitigating circumstances.   Defense counsel, in response,
    proposed that the judge ask the jury to "listen to those
    portions of the instructions . . . beginning at first degree and
    through voluntary manslaughter.    That way, we're not putting our
    thumb anywhere to push them in one direction or the other."
    Thereafter, the judge called the jury into the court room to
    respond to their note.
    In addressing the statement at issue, the judge instructed
    the jury as follows:
    "With the exception of whether or not the Commonwealth has
    proven without reasonable doubt there were mitigating
    circumstances. So I'm just reading what you wrote. And
    what I respectfully suggest, and this is why I did it, is
    that you take some time and listen to the instructions on
    the audio tape, and don't tell me whether you have or not.
    But our court monitor has given you an outline that refers
    you back to the time within the CD so you can fast forward
    it, and . . . you can quickly go to those sections that you
    want to listen to, understanding that my instructions as a
    whole are important, all of my instructions are equally
    important as I told you that.
    "So, I, again, don't want to presuppose what you're asking,
    and I'm not being critical. Please forgive me. I just am
    not able to answer the question, because it needs further
    clarification."
    The judge instructed the jury to continue their deliberations,
    emphasizing once again that the Commonwealth bears the burden to
    prove all the elements of the charged offenses.    The judge
    concluded:   "At this juncture, I'd ask you to go back, listen to
    the recording if that's helpful.    If you have further questions,
    21
    I'm happy to receive them from you.   If you want to ask
    questions right away before listening, you can do that as well."
    The jury returned to the deliberation room and asked no
    additional questions prior to returning verdicts of guilty the
    following day.
    On appeal, the defendant argues that the judge abused his
    discretion in responding to the jury's statement.    Specifically,
    he argues that, faced with the jury's misstatement that the
    Commonwealth must prove, rather than disprove, mitigating
    circumstances, the judge was required to forcefully reinstruct
    the jury on voluntary manslaughter and alert them explicitly of
    the Commonwealth's burden of proof.
    "The proper response to a jury question must remain within
    the discretion of the trial judge, who has observed the evidence
    and the jury firsthand and can tailor supplemental instructions
    accordingly."    Commonwealth v. Monteagudo, 
    427 Mass. 484
    , 488
    (1998), quoting Commonwealth v. Waite, 
    422 Mass. 792
    , 807 n.11
    (1996).   See Commonwealth v. Watkins, 
    425 Mass. 830
    , 840 (1997)
    ("The necessity, scope, and character of a judge's supplemental
    jury instructions are within his or her discretion").   "[B]efore
    a judge responds to a jury communication of legal significance
    . . . , counsel should be given the opportunity to assist the
    judge in framing an appropriate response and to place on record
    any objection they might have to the course chosen by the
    22
    judge."   Commonwealth v. Nelson, 
    468 Mass. 1
    , 16 (2014), quoting
    Commonwealth v. Floyd P., 
    415 Mass. 826
    , 833 (1993).     Here,
    defense counsel was given such an opportunity; he agreed with
    the judge's course of action and lodged no objection to the
    judge's response to the jury question.   Thus, we review to
    determine whether there was error and, if so, whether the error
    created a substantial likelihood of a miscarriage of justice.
    See Commonwealth v. Scott, 
    428 Mass. 362
    , 366 (1998), S.C., 
    437 Mass. 1008
     (2002).
    We conclude that there was no abuse of discretion.     "The
    judge's discretion to formulate a response is broad,"
    Monteagudo, 
    427 Mass. at 488
    , and "[w]e evaluate the adequacy of
    a supplemental instruction in the context of the entire charge,"
    Commonwealth v. West, 
    487 Mass. 794
    , 804 (2021).   It is
    undisputed that the jury instructions given at the close of
    evidence, which were memorialized verbatim in the audio
    recording, accurately and thoroughly conveyed that the
    Commonwealth bore the burden to prove that there were no
    mitigating circumstances.   In fact, this precise instruction was
    repeated no less than seven times during the main jury charge.
    See Watkins, 
    425 Mass. at 840
     ("We presume that a jury follow
    all instructions given to [them] . . .").
    Based on the jury's statement that they were "in agreement
    with charge" except as to "whether or not Commonwealth has
    23
    proven without reasonable doubt there were mitigating
    circumstances," the judge could not discern confidently which
    offense their statement concerned; the given instructions on
    murder in the first degree, murder in the second degree, and
    voluntary manslaughter each contained statements addressing the
    Commonwealth's burden to disprove mitigating circumstances.    The
    judge therefore concluded that the jury's statement needed
    clarification.
    Rather than provide a specific instruction on voluntary
    manslaughter, as the defendant now argues he should have, the
    judge agreed with defense counsel's suggestion to not "push [the
    jury] in one direction" and instead pointed the jury to the
    audio recording as a whole, guided by the outline.    The outline
    contained headings for each offense and the accompanying
    instructions, including headings entitled "No Mitigating
    Circumstances" under each theory of murder in the first degree,
    and "What is a Mitigating Circumstance?" under voluntary
    manslaughter.    This allowed the jury to direct themselves to the
    portion of the instructions giving them pause.    Significantly,
    the judge encouraged the jury to clarify their statement or ask
    additional questions, if they had them, after listening.     It was
    within the judge's considerable discretion to respond in this
    24
    manner.10   See Scott, 
    428 Mass. at 367
     (no abuse of discretion
    where "judge was unclear what the jurors were asking and, rather
    than confuse them, the judge sought further clarification of the
    question which concerned the jurors").
    The defendant argues that, because the judge used the word
    "suggest" when he initially told the jury to listen to the
    recording, we cannot know whether the jury actually listened to
    the recording of the judge's instructions, and a substantial
    likelihood of miscarriage of justice therefore resulted.     We
    disagree.   Considering all of the judge's statements to the jury
    together and in context, rather than in isolation, his response
    clearly reflected an instruction for the jury to clarify their
    statement by listening to the audio recording.    See Commonwealth
    v. Stokes, 
    440 Mass. 741
    , 750 (2004), S.C., 
    460 Mass. 311
     (2011)
    ("adequacy of instructions is determined by their over-all
    impact on the jury").   The absence of any follow-up questions or
    clarification from the jury "suggests that their confusion was
    dispelled."   Monteagudo, 
    427 Mass. at 489
    .   "The jurors may
    withdraw a question or return a verdict before a question is
    10Contrary to the defendant's argument, it was sufficient
    for the judge to use an audio recording of the instructions,
    rather than a written version, especially where, as here, the
    jury were provided the outline. See Commonwealth v. Baseler,
    
    419 Mass. 500
    , 505 (1995) ("a tape recording is not only a
    reasonable procedure by which to make the judge's instructions
    available to the jury, but also is comparable to written
    instructions").
    25
    answered."   Scott, 
    428 Mass. at 367
    .    The jury were "in the best
    position to determine whether the additional instruction was
    necessary," and by returning their verdicts without clarifying
    their statement, they demonstrated that they did not need
    further response from the judge.   
    Id.
    The jury's misstatement in this case -- that the
    Commonwealth is required to prove mitigating circumstances
    beyond a reasonable doubt -- is not unfamiliar or surprising.
    The concept that the Commonwealth bears the burden to disprove
    mitigating circumstances is difficult to frame, and we have
    decided a number of cases where judges have stated the concept
    incorrectly during jury instructions.11    However, even where a
    judge has misstated the Commonwealth's burden in the very same
    manner as the jury did here, we have not found a substantial
    likelihood of a miscarriage of justice where "the center of
    gravity" of the judge's instructions was not "strongly on the
    11This error -- where a judge instructs the jury that the
    Commonwealth must prove mitigating circumstances beyond a
    reasonable doubt -- has been referred to as the Acevedo error.
    See Acevedo, 
    427 Mass. at 716
     (judge instructed jury that
    Commonwealth "must prove three elements beyond a reasonable
    doubt," including that "the defendant injured [the victim] as a
    result of sudden combat or in the heat of passion or using
    excessive force in self defense"). See, e.g., Commonwealth v.
    Brum, 
    441 Mass. 199
    , 205 (2004); Commonwealth v. Lynch, 
    439 Mass. 532

     (2003); Commonwealth

    side of the misstatement" (citation omitted).   Commonwealth v.
    Fickling, 
    434 Mass. 9
    , 20 (2001).   See, e.g., Commonwealth v.
    Lynch, 
    439 Mass. 532
    , 543-544, cert. denied, 
    540 U.S. 1059
    (2003) (judge provided two correct instructions and two
    incorrect instructions, but "repeatedly emphasized that the
    Commonwealth bears the burden of proof beyond a reasonable doubt
    on all the elements of the crime charged"); Fickling, 
    supra at 19-20
     (two correct instructions sandwiched between two incorrect
    instructions, but it was clear that correct instructions carried
    more weight).   Contrast Acevedo, 
    427 Mass. at 716-717
     (new trial
    required where judge incorrectly instructed on burden of proof
    as to provocation in main charge twice, with one correct
    instruction, and repeated incorrect instruction in supplemental
    charge).
    In these circumstances, where the jury were correctly,
    consistently, and repeatedly instructed in the main charge that
    the Commonwealth bears the burden to prove that there were no
    mitigating circumstances, were provided an audio recording of
    those instructions, and were encouraged to clarify their
    statement or ask additional questions after listening to the
    recording, but did not do so, it would be entirely speculative,
    and remote in the extreme, to conclude that the jury applied an
    incorrect burden of proof in reaching their verdict.   See
    Watkins, 
    425 Mass. at 841
    .   See also Commonwealth v. Torres, 420
    
    27 Mass. 479
    , 490-491 (1995) ("Reviewing the whole charge,
    including the judge's emphatic and repeated statements that only
    the Commonwealth -- and never the defendant -- bore any burden,
    we believe that the jury could not have concluded that the
    judge's misstatement created an unconstitutional presumption
    relieving the State of its burden of persuasion beyond a
    reasonable doubt of every element of deliberately premeditated
    murder in the first degree").   We discern no substantial
    likelihood of a miscarriage of justice.12
    5.   Constitutionality of life sentence without possibility
    of parole.   The defendant argues that, considering his age of
    eighteen at the time of crimes and the surrounding
    circumstances, the reasoning in Diatchenko I, 
    466 Mass. at
    667-
    671, and Miller, 
    567 U.S. at 479-480
    , commands a conclusion that
    his sentence of life without the possibility of parole is
    unconstitutional under art. 26 and the Eighth Amendment.     Since
    we concluded in Diatchenko I that a life sentence without the
    possibility of parole for individuals under the age of eighteen
    violates art. 26, "we repeatedly have declined to extend its
    holding to individuals over eighteen years of age."
    Commonwealth v. Watt, 
    484 Mass. 742
    , 755 (2020).
    12Therefore, the defendant's claim of ineffective
    assistance based on counsel's failure to object to the judge's
    response is unavailing. See Kolenovic, 478 Mass. at 192.
    28
    Recently, however, in Watt, we concluded that "it likely is
    time for us to revisit the boundary between defendants who are
    seventeen years old and thus shielded from the most severe
    sentence of life without the possibility of parole, and those
    who are eighteen years old and therefore exposed to it."      Id. at
    755-756.   In order to do so, we determined that it was necessary
    for there to be "an updated record reflecting the latest
    advances in scientific research on adolescent brain development
    and its impact on behavior."     Id. at 756.   We therefore remanded
    that case to the Superior Court for a development of the record
    to "allow us to come to an informed decision as to the
    constitutionality of sentencing young adults to life without the
    possibility of parole."   Id.
    The defendant acknowledges that any decision we make based
    on a developed record regarding the constitutionality of a life
    sentence without the possibility for parole for individuals over
    eighteen years of age will be applicable to him.      See
    Commonwealth v. Penn, 
    472 Mass. 610
    , 628 (2015), cert. denied,
    
    578 U.S. 925
     (2016) (rules announced in Miller and Diatchenko I
    given retroactive effect).      Nonetheless, he contends that we
    should make this constitutional determination on the record
    before us.   Because the record in this case does not contain the
    necessary information for us to "come to an informed decision"
    29
    on this important constitutional question, we decline to do so
    here.     See Watt, 484 Mass. at 756.
    6.    Review pursuant to G. L. c. 278, § 33E.   The defendant
    asks us to exercise our authority pursuant to G. L. c. 278,
    § 33E, to reduce his conviction of murder in the first degree to
    murder in the second degree or voluntary manslaughter based on
    the lack of evidence of extreme atrocity or cruelty.
    The defendant was tried before we prospectively changed the
    requirements of finding extreme atrocity or cruelty in
    Commonwealth v. Castillo, 
    485 Mass. 852
    , 865-867 (2020).     As a
    result, the jury were instructed that a finding of extreme
    atrocity or cruelty must be based on at least one of the so-
    called Cunneen factors.     See Commonwealth v. Cunneen, 
    389 Mass. 216
    , 227 (1983).     "These include '[1] indifference to or taking
    pleasure in the victim's suffering, [2] consciousness and degree
    of suffering of the victim, [3] extent of physical injuries, [4]
    number of blows, [5] manner and force with which delivered, [6]
    instrument employed, and [7] disproportion between the means
    needed to cause death and those employed.'"     Commonwealth v.
    Gonsalves, 
    488 Mass. 827
    , 834 (2022), quoting Cunneen, 
    supra.
    Based on the evidence that the defendant stabbed the victim
    -- who was unarmed -- nine times with a knife, causing his
    intestines to protrude from his body while he lay on the ground
    conscious and waiting for medical aid, a finding of extreme
    30
    atrocity or cruelty was supported by several of the Cunneen
    factors.   See Gonsalves, 488 Mass. at 834-835 (finding of
    extreme atrocity or cruelty supported where defendant stabbed
    victim five times and in vital areas, and where, after stabbing,
    victim was conscious and attempted to speak to friends);
    Commonwealth v. Rodriquez, 
    461 Mass. 100
    , 104-105 (2011)
    (finding of extreme atrocity or cruelty supported where
    defendant stabbed unarmed victim seven times with "significant
    force" in "areas in the body that were likely to cause serious
    injury and pain"); Commonwealth v. Libby, 
    405 Mass. 231
    , 237
    (1989), S.C., 
    411 Mass. 177
     (1991) (evidence sufficient to prove
    extreme atrocity or cruelty where defendant stabbed victim nine
    times).
    The defendant compares this case to Castillo, 485 Mass. at
    867-868, where we reduced a verdict of murder in the first
    degree based on the theory of extreme atrocity or cruelty to
    murder in the second degree, pursuant to our authority under
    G. L. c. 278, § 33E.   Castillo is inapposite.   There, the
    defendant fired a single gunshot in the victim's back, and the
    only evidence that supported a finding of extreme atrocity or
    cruelty was the victim's consciousness of suffering.    Id. at
    860, 867-868.   The same is not true here.   See Libby, 
    405 Mass. at 236
     ("Had there been but one stab wound, we might well have
    regarded this case as one of a class not typically involving
    31
    murder in the first degree").   Our "authority to reduce a
    conviction of murder in the first degree in the interest of
    justice 'should be used sparingly and with restraint.'"
    Commonwealth v. Billingslea, 
    484 Mass. 606
    , 619-620 (2020),
    quoting Commonwealth v. Brown, 
    477 Mass. 805
    , 824 (2017), cert.
    denied, 
    139 S. Ct. 54 (2018)
    .   We decline to exercise that
    authority in these circumstances.13
    Conclusion.   We affirm the defendant's convictions and the
    order denying the defendant's motion for a new trial.
    So ordered.
    13The defendant argues that the cumulative effect of the
    errors requires a new trial. "Here, 'the cumulative [effect of
    the] errors . . . [was] no more prejudicial than any individual
    errors, which had minimal impact, if any.'" Commonwealth v.

    Duran,
