Question #1564

Eliminating Answers Through Relevance

The Key Takeaway in this question said that "none of these answer choices were easy eliminations because of different quantifiers in the premises or conclusion." However, I immediately eliminated answers A, C, and D because of the difference in wording from the stimulus. How it's "as a scientist, she knows that no scientist" compared to "as an expert in biology, he knows that no marsupial." The stimulus speaks for a group itself, not about things that the group has expertise on. From there it was pretty simple. Was I correct in immediately eliminating those answers, or did I just get a bit lucky?

    @oliverdyche, I'd get rid of A because we want the conclusion to be a "some" statement that connects the negation of the necessary conditions in the first two conditional statements of the argument. With A, we have a "some" statement that's connecting the necessary condition of both of the statements, so this is a valid argument. I'd eliminate C because we need the conclusion to be a "some" statement, and this answer choice concludes with an "all" statement. I'd eliminate D because it's a valid argument. It can't be a match because the stimulus is invalid.

    I understand those reasons for eliminating, yes, but is the reason I gave a valid one to use to eliminate the other answers?

    I have the same question.

    Hi, I think that is indeed a valid way to eliminate them.
