Answer Choice C

I'm really confused. Why is it that we can take A-some-F --> not CEC from one of the PR's to conclude A-some-not CEC, yet with another answer choice we cannot take CA-most-WMC-->= not BWO to conclude CA-most-=not BWO?? the structure of the premises that lead to the conclusions are the exact same yet we can't conclude anything for answer choice C? Thanks!

@Grace-Lurker, happy to help!

We stop in (C) because we can already see that the logical pattern is different from that of the passage. For efficiency's sake, there is no point in continuing to try to work out this answer choice when we are looking for an answer choice with parallel flawed reasoning.

In the passage and in (A), the sufficient condition of the conditional S->N statement (in the passage this is "Scientist" and in (A) this is "Father") is the same term that is used in the first half of the most statement. In (C), the sufficient condition of the conditional S->N statement (which is "Aged in Metal") is used in the second half of the most statement instead of in the first half. Therefore, the logic is different and we can save time by eliminating the answer choice at this point rather than continuing to work it out to find a conclusion, especially since we are looking for flawed logic.

Does that make sense? Please let us know if you have any other questions!
