    
    Of the   Federal   Circuit    Court   of   Appeals,   sitting   by
    designation.
    KAYATTA,   Circuit   Judge.   A   jury   convicted   Carlos
    Camacho-Santiago ("Camacho") of two counts of drug trafficking
    based on his involvement in a criminal conspiracy to move cocaine
    in luggage stowed on commercial airline flights from Puerto Rico
    to the mainland United States.    On appeal, Camacho raises an array
    of challenges to his conviction based on the contention that he
    was not a member of the conspiracy proven at trial.    He also argues
    that his conviction depended upon the erroneous admission of
    hearsay evidence and that the district court failed to do enough
    to ensure the jury could fairly render a verdict.        Finding the
    evidence sufficient to sustain his conviction as a member of the
    conspiracy charged in the indictment and proven at trial, and
    finding no other reversible error, we affirm.
    I.   Background
    In May 2012, a grand jury indicted Camacho and nineteen
    others on two criminal counts arising out of a drug trafficking
    conspiracy.   We described the charged conspiracy in our recent
    opinion vacating the conviction of another individual, Nelson
    Pereira.   See United States v. Pereira, 
    848 F.3d 17
    , 19–20 (1st
    Cir. 2017).    In brief, the indictment alleged that Wilfredo
    Rodríguez-Rosado ("Rodríguez")--not indicted here--created and ran
    an operation using baggage handlers to smuggle cocaine on American
    Airlines flights from Puerto Rico to the mainland over roughly a
    - 2 -
    ten-year period beginning in 1999.       The indictment charged Camacho
    with two counts of joining and aiding and abetting this conspiracy.
    Rodríguez did not oversee the distribution process in
    the continental United States, nor was he the original source of
    the cocaine that made its way onto American Airlines flights.          The
    cocaine was furnished by a variety of suppliers who brought their
    cocaine supply to Rodríguez's people and worked with them to get
    cocaine packaged and delivered to American Airlines employees at
    Luis Muñoz Marín International Airport in San Juan.             One such
    supplier was Carlos Arce Lopez ("Arce"), who first connected with
    Rodríguez through Camacho.
    Gerardo    Torres   Rodríguez     ("Torres"),   one    of    the
    government's   key   witnesses   against     Camacho,   testified     that
    Rodríguez offered to forgive a debt Camacho owed him if Camacho
    brought him a new supplier, and that Camacho accepted that offer
    by bringing Arce to Rodríguez.     According to Torres, on at least
    three occasions, Camacho traveled with him to Newark to test the
    route for Arce, pick up suitcases of drugs, and collect money to
    return to Puerto Rico.    Arnaldo Sierra-Menendez ("Sierra") also
    testified that Camacho worked for Arce and that on one occasion
    when some cocaine went missing, Camacho and Rodríguez confronted
    Sierra about his involvement in the drugs' disappearance.           Sierra
    testified that Camacho pointed a gun at him while asking what
    happened to the cocaine and threatening to kill him.            The only
    - 3 -
    other witness who offered first-hand testimony as to Camacho's
    involvement in the conspiracy was Javier Olmo-Rivera ("Olmo"), a
    member   of    Rodríguez's   organization   who   testified   that   every
    supplier had an intermediary who delivered the cocaine to the
    airport and facilitated the trafficking group's connection to the
    supplier, and that Camacho was the person who delivered Arce's
    cocaine.
    Rodríguez did not testify, but many other members of the
    conspiracy did.     Torres and Sierra both testified as to statements
    Rodríguez made concerning the conspiracy and Camacho's alleged
    role in it, testimony the court allowed as relating out-of-court
    statements of a coconspirator.      The jury convicted Camacho on both
    counts, and the judge sentenced him to 360 months' imprisonment.
    This timely appeal followed.
    II.   Discussion
    Camacho begins with two arguments that train on the
    nature of the conspiracy proven at trial.          He contends that the
    evidence was insufficient to convict him of the one conspiracy
    charged.      Alternatively, he contends that the jury should have
    been told more expressly that proof of multiple conspiracies rather
    than the one conspiracy alleged in the indictment was not grounds
    for conviction.      Third, Camacho challenges the admission of what
    he says is hearsay evidence.         Fourth, he requests a new trial
    because he claims the jury was twice contaminated. Fifth, he avers
    - 4 -
    that the court read testimony back to the jury during deliberations
    without taking adequate steps to ensure the jury did not place
    undue weight on what it heard.1                    We address these arguments in
    their logical order.
    A.     One Conspiracy, Or More?
    The indictment alleged a conspiracy to "possess with
    intent to distribute [cocaine]."                     The specific object of the
    conspiracy      was    "to       smuggle    into    American    Airlines    commercial
    aircrafts, suitcases filled with large amounts of cocaine to be
    transported from Puerto Rico to the continental United States with
    the intent to generate and obtain large monetary profits." Against
    this       backdrop,       the    essence    of     Camacho's    conspiracy-related
    arguments is that the evidence showed at least two conspiracies,
    not one, and he was not a part of the only one alleged in the
    indictment.           To    demonstrate      the    existence     of   at   least   two
    conspiracies rather than one, he describes the evidence as perhaps
    showing him in a conspiracy with Arce, as Arce's employee, to
    supply cocaine to Rodríguez, who in turn ran a separate conspiracy
    1
    In the table of contents to his opening brief, Camacho also
    lists as one issue for review whether "the district court committed
    reversible error by applying a higher than legally mandated
    guideline range for Mr. Camacho and when it sentenced Camacho to
    360 months based on such erroneous guideline." His briefs, though,
    never address this issue or argue that such error occurred. The
    issue is therefore waived. See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990) ("[I]ssues adverted to in a perfunctory
    manner, unaccompanied by some effort at developed argumentation,
    are deemed waived.").
    - 5 -
    to smuggle cocaine into the continental United States.           This "two-
    conspiracy" description provides the launch pad for two arguments:
    the evidence was insufficient to convict Camacho of a single
    conspiracy; alternatively, the evidence was at least ambiguous
    enough to warrant what Camacho calls a "multiple conspiracy"
    instruction.      By that he means an instruction telling the jury
    that it should decide whether the government has proved one or
    multiple conspiracies, and that Camacho must be found not guilty
    if he did not join the conspiracy alleged, even if he joined
    another.      Camacho requested such an instruction, but it was not
    given.     Because the argument challenging the instructions is an
    easier one for a defendant to support, we address it first.
    "A trial court should grant a defendant's request for a
    multiple conspiracy instruction if, on the evidence adduced at
    trial, a reasonable jury could find more than one such illicit
    agreement, or could find an agreement different from the one
    charged."      United States v. Ramírez-Rivera, 
    800 F.3d 1
    , 45 (1st
    Cir. 2015) (quoting United States v. Brandon, 
    17 F.3d 409
    , 449
    (1st   Cir.    1994)).    "To   determine   whether   a   set   of   criminal
    activities constitutes a single conspiracy, we generally look to
    three factors:      (1) the existence of a common goal, (2) overlap
    among the activities' participants, and (3) interdependence among
    the participants."       United States v. Ciresi, 
    697 F.3d 19
    , 26 (1st
    Cir.     2012).    "A    general   scheme   may   exist   'notwithstanding
    - 6 -
    variations in personnel and their roles over time.'"    
    Id.
     (quoting
    United States v. Shea, 
    211 F.3d 658
    , 665 (1st Cir. 2000)).    "'The
    goal of selling cocaine for profit' satisfies the common goal
    requirement.   That each defendant had an interest in furthering
    the distribution of cocaine is also sufficient evidence that they
    shared a common goal with the other participants."     United States
    v. Portela, 
    167 F.3d 687
    , 695 (1st Cir. 1999) (footnotes and
    citation omitted) (quoting United States v. Wilson, 
    116 F.3d 1066
    ,
    1075 (5th Cir. 1997)).
    We review a preserved challenge to a district court's
    decision not to provide a multiple conspiracy instruction for abuse
    of discretion, but "[w]e will reverse a district court's decision
    not to provide a multiple conspiracy instruction only if the
    defendant can show that he suffered substantial prejudice." United
    States v. Díaz, 
    670 F.3d 332
    , 350 (1st Cir. 2012) (citing United
    States v. De La Cruz, 
    514 F.3d 121
    , 139 (1st Cir. 2008)).    "In the
    context of alleged multiple conspiracies, the defendant's main
    concern is that jurors will be misled into attributing guilt to a
    particular defendant based on evidence presented against others
    who were involved in a different and separate conspiratorial
    scheme."   Brandon, 
    17 F.3d at 450
    .
    The evidence at trial, to the extent it pointed a finger
    at Camacho, was unambiguous on three points:   securing a supply of
    cocaine was an essential element of Rodríguez's conspiracy to
    - 7 -
    distribute; Rodríguez recruited Camacho into the conspiracy to
    find a supplier; and Camacho knew, in great detail, how the
    smuggling portion of the conspiracy operated, and actually tested
    out the route and delivered drugs and money himself.        In short, if
    the evidence was to be believed at all, there was:             (1) "the
    existence     of   a   common   goal,      (2)   interdependence      among
    participants, and (3) overlap among the participants."             United
    States v. Dellosantos, 
    649 F.3d 109
    , 111 (1st Cir. 2011).
    The fact that the conspiracy had several integrated
    steps does not mean that each step could reasonably be seen as a
    separate conspiracy, at least where the evidence shows Camacho was
    aware of all the steps.      See, e.g., United States v. Hansen, 
    434 F.3d 92
    , 101 (1st Cir. 2006) (observing that it was not plainly
    erroneous for a district court to refuse to give a multiple
    conspiracy     instruction   where   the    evidence   demonstrated    the
    defendant knew the extent of the conspiracy alleged and acted in
    furtherance of it).     A person need not be involved at every level
    of a conspiracy to be a participant in it.         See Brandon, 
    17 F.3d at 451
    .     At any point in time in the course of the conspiracy, it
    could be said of Camacho that which the indictment alleged:             he
    was involved in a scheme to possess cocaine with the intent of
    shipping it on commercial flights into the continental United
    States for sale.       By supplying drugs to Rodríguez and ensuring
    that those drugs successfully made their way through his packaging-
    - 8 -
    and-distribution operation, Camacho's "aspect of the scheme [was]
    necessary    [and]     advantageous    to     the   success   of"     Rodríguez's
    distribution scheme.       Portela, 
    167 F.3d at 695
    .           To find on this
    evidence that Camacho was engaged only in a conspiracy with Arce
    to supply cocaine to Rodríguez would be like saying that a center
    on a football team was engaged only in a conspiracy to supply the
    ball to the quarterback but was otherwise not a part of the team.
    Nor did the government's case suggest any alternative
    conspiracy that might have attracted jurors as a possible basis
    for convicting Camacho. He does point to two snippets of testimony
    that Rodríguez and Camacho met each other when they "started"
    "doing business" with an individual named Tun Tun.                   The evidence
    was obviously aimed at explaining how Camacho and Rodríguez met.
    It concerned events "much" before 1999.             While a juror could have
    inferred that the "business" was drug smuggling, the testimony
    contained no details at all about any smuggling at that time, or
    about Camacho's involvement.          Nor was it presented or argued as a
    possible alternative conspiracy upon which jurors might rest a
    verdict.
    Camacho    also   argues       that    a     multiple     conspiracy
    instruction was necessary because of evidence of a smuggling
    conspiracy that predated the one alleged and that involved Sierra,
    Rodríguez, and another drug trafficker; evidence of a similar,
    concurrent    drug-trafficking    conspiracy         in   which     another   drug
    - 9 -
    trafficker used Rodríguez's same smuggling method and facilities
    to ship cocaine to the mainland United States; and the government's
    references to other drug traffickers separately working to supply
    Rodríguez with cocaine for his smuggling operation.            But Camacho
    does not argue, nor does the record show, that the government's
    evidence purported or even attempted to show that Camacho was a
    participant in any of these other conspiracies.            Simply put, the
    government did not adduce evidence tending to show that Camacho
    was   involved   in   any   conspiracy   but   the   one   alleged   in   the
    indictment.
    Adding belt to suspenders, we note that the district
    court told the jury that it needed to find beyond a reasonable
    doubt "that the agreement specified in the Indictment, and not
    some other agreement or agreements, existed between at least two
    people . . . to possess with intent to distribute cocaine."                We
    have found virtually identical instructions sufficient in similar
    cases in which a defendant challenged a district court's refusal
    to give a multiple conspiracy instruction.           See United States v.
    Niemi, 
    579 F.3d 123
    , 126–27 (1st Cir. 2009); United States v.
    Balthazard, 
    360 F.3d 309
    , 315–16 (1st Cir. 2004).           And while more
    might be said on the matter by a judge in a case posing a greater
    risk of confusion, see, e.g., United States v. Trainor, 
    477 F.3d 24
    , 34 & n.20 (1st Cir. 2007), this was not such a case.
    - 10 -
    The foregoing discussion also removes the heart from
    Camacho's insufficiency argument, which rests on the assertion
    that there was no evidence of the single conspiracy charged. Here,
    the indictment, the evidence, the instructions, and the verdict
    all aligned:    at Rodríguez's request, Camacho secured a supply for
    the smuggling pipeline and otherwise knowingly assisted in using
    the pipeline to convert cocaine into dollars by shipping it from
    Puerto Rico for sale in the mainland United States.
    B.    Hearsay
    Camacho's hearsay argument trains on the trial court's
    admission of the testimony by Torres and Sierra relating what
    Rodríguez    told    them     about    Camacho's        role   in    the       conspiracy.
    Camacho's principal argument challenging the admission of that
    testimony    relies    on     his   claim    that     he   was      not    a    member    of
    Rodríguez's conspiracy, thus Rodríguez's out-of-court statements
    were not admissible against him.             This argument fails in the wake
    of our determination that the evidence amply supported a finding
    that the two were in the conspiracy together.
    That    leaves    Camacho      with    a    second,      more       technical
    argument.    He points out that when affirming a tentative decision
    to   admit   the     challenged       testimony     subject      to       proof    of    the
    conspiracy, and in listing the names of the conspirators, the
    district     court    neglected       to    mention      the   undisputed          leader,
    Rodríguez, by name.         Having read the district court's comments, we
    - 11 -
    think it fairly plain that the court was including the leader of
    the conspiracy even though the court did not mention him by name.
    Guided    by    the   initial   objections,    none    of   which   challenged
    Rodríguez's role as a leader of the conspiracy, the court appears
    to have been concerned not with listing every person who, by a
    preponderance of the evidence, appeared to be a member of the
    conspiracy, but rather, with listing the testifying witnesses
    capable   of     relaying   the   statements   of     their    named-defendant
    coconspirators.         In any event (and likely because Rodríguez's
    inclusion was obvious), Camacho did not object or in any way point
    out the exclusion when it was clear that the court would have
    readily confirmed our reading of its statement if asked.                    The
    objection is therefore forfeited (if not waived) and our foregoing
    discussion of the conspiracy evidence negates any possibility of
    finding plain error.
    C.    Jury Contamination
    Camacho trains his final two arguments on the district
    court's handling of two procedural issues separate and distinct
    from the issues of proof discussed above.
    A week into Camacho's trial, Juror Number 23 advised the
    U.S. Marshal assigned to the jury that Camacho's stepson had
    approached her at her place of business.           The Marshal informed the
    court, which conducted voir dire of the juror in the presence of
    the   parties     and   outside   the   presence    of   the    other   jurors.
    - 12 -
    Questioning revealed that Camacho's stepson had approached Juror
    Number     23     to      tell    her    that     the    case   against     Camacho      was
    "fabricated" and Camacho was "a good person."                          Juror Number 23
    also indicated that she had not spoken to any other jurors about
    the   incident.            The    government       argued    for    Juror   Number       23's
    dismissal; Camacho and his codefendants argued against it.                               The
    district        court      sided       with      the    government,     excusing      Juror
    Number 23--in the presence of the rest of the jury--because of the
    "situation" in which she had been "involved" and advising her to
    "not contact any of the jurors about this case or what happened or
    anything having to do with this case."                     Juror Number 23 agreed and
    departed.            No    party       lodged     any    objection     to   the     court's
    instructions to Juror Number 23.
    A few weeks later, a second, unrelated incident occurred
    involving prosecution witness Juan Delgado-Biaggi ("Delgado"), a
    former American Airlines crew chief who had participated in the
    drug smuggling operation. Delgado advised a court security officer
    that he recognized Juror Number 60. The officer informed the court
    and a recess was called.                  After questioning Delgado outside the
    presence of the jury, the court questioned Juror Number 60 outside
    the presence of the other jurors (and Delgado).                         Juror Number 60
    told the court that he had seen Delgado working as an American
    Airlines    employee.             He    also     informed   the     court   that    he   had
    mentioned       as     much      to    another    juror,    Juror     Number   8,    during
    - 13 -
    Delgado's testimony.     Juror Number 60 told the court that he had
    not made any other comments to any other members of the jury.
    Shortly thereafter, the court questioned Juror Number 8.
    Juror Number 8 stated that she did not know whether or not Juror
    Number 60 said anything to her about Delgado, explaining, "I know
    I heard that he told me that one of them he kind of seen him--
    like, he recognizes as he saw him, but he didn't make it for sure.
    He didn't say for sure, as far as I know."             She said that she
    "didn't talk to anybody about it" and that it would "[n]ot at all"
    affect her impartiality.       The court denied the defendants' request
    for   complete   voir   dire    of   the   entire   jury   and   denied   the
    defendants' subsequent motion for a mistrial.              The court then
    excused Juror Number 60 and instructed him to have no further
    contact with the other jurors.         It did not excuse Juror Number 8,
    but it did instruct her to refrain from discussing the incident.
    On appeal, Camacho argues that the district court abused
    its discretion when it refused to conduct full voir dire to ensure
    that no other jurors were affected by either incident.2            As to the
    2Camacho appears also to argue that by obliquely referring
    to Juror Number 23's "situation" in the presence of the other
    jurors, the district court created some measure of mistrust or
    bias against the defendants.    Camacho did not raise this issue
    below, so we review for plain error. See United States v. DeLeon,
    
    187 F.3d 60
    , 67 (1st Cir. 1999). We do not see how the court's
    vague, euphemistic reference to Juror Number 23's run-in with
    Camacho's stepson could have engendered in the minds of the
    remaining jurors anything more than curiosity. The district court
    did not plainly err.
    - 14 -
    first incident (involving Juror Number 23), we find that Camacho
    has waived any argument challenging the trial court's failure to
    question the entire jury.              When the government sought Juror
    Number 23's removal because of her contact with a person friendly
    to the defense, Camacho objected, arguing that the juror testified
    that she could remain impartial and did not feel threatened.
    Having affirmatively made such an argument below, Camacho cannot
    now argue on appeal that it was plain error for the court not to
    investigate       further    whether     other    jurors    may       have   been
    contaminated by Juror Number 23 to Camacho's prejudice. See United
    States v. Gaffney-Kessell, 
    772 F.3d 97
    , 100 (1st Cir. 2014)
    (observing that waiver occurs where a party's actions "ring not of
    oversight,    inadvertence,     or   neglect     in   asserting   a    potential
    right, but rather of a deliberate course of conduct" (citation
    omitted)).
    As   to   the    second     incident,     Camacho    joined      his
    codefendants in arguing for full voir dire and objecting to the
    court's decision to retain Juror Number 8, so we review the court's
    decision for abuse of discretion.             See United States v. Morosco,
    
    822 F.3d 1
    , 13 (1st Cir. 2016).            In response to a nonfrivolous
    claim that a jury might be biased or contaminated, a district court
    is required to inquire into whether contamination occurred and, if
    so, whether such contamination was prejudicial.            See United States
    v. Zimny, 
    846 F.3d 458
    , 464 (1st Cir. 2017); United States v.
    - 15 -
    Bristol-Mártir, 
    570 F.3d 29
    , 42 (1st Cir. 2009).             "[T]he trial
    court has wide discretion to fashion an appropriate procedure for
    assessing whether the jury has been exposed to substantively
    damaging information, and if so, whether cognizable prejudice is
    an inevitable and ineradicable concomitant of that exposure."
    United States v. Bradshaw, 
    281 F.3d 278
    , 290 (1st Cir. 2002).          We
    will defer to a trial court's finding that the jury was not
    contaminated "[s]o long as the district judge erects, and employs,
    a suitable framework for investigating the allegation and gauging
    its effects, and thereafter spells out his findings with adequate
    specificity to permit informed appellate review."          United States
    v. Boylan, 
    898 F.2d 230
    , 258 (1st Cir. 1990).
    Camacho   argues   that   the   district   court    abused   its
    discretion because it did not do enough to ascertain whether Juror
    Number 60's recognition of a witness and the juror's act of
    disclosing such recognition to one of his fellow jurors led to
    contamination.   As an initial matter, we find the claim of bias or
    contamination tenuous at best. After all, the witness's employment
    was not a matter of dispute, and Juror Number 60 merely reported
    that he had seen the witness before and knew the witness worked
    for American Airlines.    While the cautious judge with an available
    alternate did not abuse his discretion in excusing Juror Number 60,
    that decision did not turn Juror Number 60 into a Typhoid Mary of
    bias   warranting   any   extraordinary    effort    to   root   out   all
    - 16 -
    contamination.      In any event, the district court took adequate
    steps to ensure that Juror Number 60's comments to Juror Number 8
    had no effect on Juror Number 8's ability to decide the case
    impartially and that those comments were not shared with any other
    members of the jury.         On this record, the district court was
    entitled to deem the jurors' explanations credible.               We, in turn,
    have no reason not to believe that both jurors followed the court's
    instructions.     See United States v. Pagán-Ferrer, 
    736 F.3d 573
    ,
    587–88 (1st Cir. 2013); see also Correia v. Fitzgerald, 
    354 F.3d 47
    , 52 (1st Cir. 2003) ("Assuming that venirepersons pass through
    this screen [of voir dire], the trial court may operate on the
    presumption     that   the   chosen   jurors    will       obey   the   judge's
    instructions to put extraneous matters aside and decide each case
    on its merits."). The district court did not abuse its discretion.
    D.   Testimony Read-Back
    Camacho's final challenge concerns the district court's
    handling of the jury's request to hear certain testimony read back
    after the jury began deliberations.            During deliberations, the
    jury sent a note to the court asking to hear Torres's testimony
    again.   The parties agreed that the court would read back Torres's
    entire testimony, including both direct and cross examination.
    The jury returned to the courtroom and the courtroom deputy read
    Torres's   direct      examination,   including        a    portion     of   the
    examination in which Torres explained that he had traveled with
    - 17 -
    Camacho from New Jersey to Puerto Rico.          When the court finished
    reading Torres's direct testimony, the jury sent a note to the
    court stating: "[W]e do not need to hear the contra-interrogatory.
    Thank you for your support.         Respectfully."         The court without
    objection polled the jury, and every one of the jurors confirmed
    that they did not want to hear cross-examination again.             The court
    thus allowed the jury to resume deliberations without hearing
    Torres's cross-examination anew.            The court shortly thereafter
    admonished the jury not to place additional weight on Torres's
    direct testimony just because they did not rehear the cross.
    Camacho   argues   on    appeal    that   the    court   committed
    reversible error by reading back Torres's direct testimony without
    reading back his testimony on cross-examination.            Camacho contends
    that the court's choice to permit the jury to return to the jury
    room without rehearing Torres's complete testimony kept the jury
    from hearing Torres state that, contrary to his direct testimony
    that he and Camacho returned to Puerto Rico from a trip to New
    Jersey they took together, he in fact flew back from Philadelphia
    while Camacho flew back from New Jersey.             As Camacho sees it,
    Torres effectively recanted his direct testimony on cross. Camacho
    argues   that   Torres's   contradictory       testimony     undermined   the
    government's proof and demonstrated Torres's lack of credibility.
    According to Camacho, allowing Torres's direct testimony to be
    heard without his cross-examination functionally rehabilitated
    - 18 -
    Torres as a witness and reasserted his faulty testimony.     Camacho
    did not object at the time this alleged error occurred, so we
    review for plain error.    See United States v. Flores-Rivera, 
    787 F.3d 1
    , 30 (1st Cir. 2015).
    The district court did not plainly err.      For one thing,
    "our circuit has yet to establish any bright-line rules on read-
    back procedures."    
    Id.
       The district court thus could not have
    plainly erred because a plain error is one that is clear and
    obvious, and "an error will not be clear or obvious where the
    challenged issue of law is unsettled."      United States v. Goodhue,
    
    486 F.3d 52
    , 57 (1st Cir. 2007).        We need keep in mind, too, a
    jury's practical ability to decide what evidence to focus on during
    its deliberations.    Jurors might discuss part of a witness's
    testimony, or part of a document.       One simply does not normally
    know when this happens.    The fact that in this instance we happen
    to know that the jury was interested in rehearing only Torres's
    direct testimony provides no reason to force-feed the jury a read-
    back that it expressly deemed unnecessary.       In short, the court
    likely made no error, much less plain error, in declining to
    require the jury during deliberations to rehear testimony that it
    specifically stated it had no need to rehear.

    III.   Conclusion
    Finding the evidence sufficient to support the jury's
    verdict and observing no other reversible errors in the record
    below, we affirm.
