What this question is testing

Parallel Flaw

Your task

The flawed nature of the company president's argument can most effectively be demonstrated by noting that, by parallel reasoning,

Answer choices

  1. Bad Conclusion Match2% picked this

    the president of Corbin Corporation has an office that is not in Corbin's headquarters building, since almost all of the offices in Corbin's headquarters

    Nice, a quick elimination right out of the gate. The conclusion is certain of itself "the President's office is not in HQ's building". We want one that's of probably strength.

  2. Bad Conclusion Match20% picked this

    Donna has at least ten years of experience as a computer programmer, since almost every programmer who works for Coderight Software has at least

    Another quick elimination. The conclusion is certain of itself "D has at least ten years of experience". We want one that's of probably strength. Obviously, if we don't find any answers we like, we'll have to reconsider these and possibly forgive their mismatching conclusions, but we shouldn't invest any time in them on the first pass, since the conclusion is already a mismatch.

  3. Bad Conclusion Match6% picked this

    almost all of Acme's employees oppose the pending merger with Barrington Corporation, since almost all of Acme's employees are factory workers, and almost all

    Here's yet another answer with an unpromising conclusion. It definitively concludes a fact: almost all employees oppose merger. The matching conclusion should have "probably" strength.

  4. Correct51% picked this

    Robinson will probably be appointed as president of Sifton University, since almost every one of Sifton's previous presidents had a Ph.D.,

    Why this is right

    Okay, we have a "probably" conclusion: R will probably be appointed President of S.U. So we should look for a premise that says "Almost all previous Presidents of S.U." or "Most previous Presidents of S.U.". We have one: almost all previous presidents had Ph.D We just seen a premise saying that "R has a Ph.D", and that's what we get. Original Argument This Answer Almost all X's are Y. Almost all P's had Ph.D Thing A is Y. R has Ph.D. So, thing A prob X. So, R prob P.

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

  5. Valid Word Trap: last ten years21% picked this

    the novel Safekeeping will probably earn a profit for its publisher, Peninsula Press, since almost every novel published by Peninsula over the

    This one is lacking a second premise, making it seem unlikely to match the original argument. There is sort of a fact built into the conclusion that Safekeeping is a novel published by Peninsula. Here we have a rule that says "Almost every novel published by P.P. has been profitable". To recreate the original flaw, we'd need to say "Safekeeping has been profitable. Thus, Safekeeping is probably a novel published by P.P." Instead, we're saying something valid: "Safekeeping is a novel published by P.P. (implied). Thus, Safekeeping will probably be profitable."
