Stimulus

Detective: Because the embezzler must have had specialized knowledge and access to internal financial records, we can presume that the embezzler worked for XYZ Corporation as either an accountant or an actuary. But an accountant would probably not make the kind of mistakes in ledger entries that led is likely that the embezzler is one of the actuaries.

Each of the following weakens the detective’s

Answer choices

  1. Hurts Author's Explanation4% picked this

    The actuaries’ activities while working for XYZ Corporation were more closely scrutinized by supervisors than were the

    This makes it less likely that actuaries would have dared to commit the crime, since they were subject to much greater oversight.

  2. Suggests Alternate Explanation5% picked this

    There is evidence of breaches in computer security at the time of the embezzlement that could have given persons outside XYZ Corporation

    This attacks the author's intermediate conclusion, suggesting that the perpetrator didn't need to work for XYZ Corp at all; they might have hacked in.

  4. Correct54% picked this

    An independent report released before the crime took place concluded that XYZ Corporation was

    Why this is right

    This has no impact on solving the causal mystery. It just says we were warned a crime might be committed, but this doesn't tip our suspicion in either direction (accountant, actuary, or other).

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  5. Hurts Author's Explanation4% picked this

    Certain security measures at XYZ Corporation made it more difficult for the actuaries to have access to internal financial

    This makes it less plausible that the actuaries did it, since they had to jump through more security hoops than the accountants did to get at the internal financial records.
