Hi, I'm stuck on this question and would really appreciate your help. I was torn between answers B and D. B: I thought this answer was stronger, because I thought the passage was primarily concerned with reasons the wave theory was discredited (the first paragraph beings with, "the classical wa...

Ah, thank you very much! Now I see it.

Sadly, I was only able to eliminate one answer from the options (A). It seems to me like any of the remaining answers could be used to logically complete the argument. In particular, why is C the best answer? Are they conflating the word "produce [industrial emissions standards]" with &quo...

Thank you very much for the explanation!

Hi! Could you just confirm whether I'm on the right track with this one or not? Muchas gracias! B is wrong because: nowhere in the passage does it say that Noguchi had no formal scientific training E is wrong because: Noguchi's work reveals the value of scientific thinking in the arts but doesn't re...

I dunno if this is even close or not, but I had something like this: Ancestors motivated by desire to sacrifice (MDS) Humankind survive (HS) Altruism (A) premises: ~MDS --> ~HS (or HS --> MDS) MDS --> A Conclusion: Since we know HS, HS --> MDS--> A. In answer A, the premises are: Rais...

I'm not sure about this one either, but my opinion is D is probably stronger than C. C might or might not explain the discrepancy (for example, if there are fewer candidates in the poll than are currently in the running, there might not be anyone in the poll who has had president experience), but it...

I was torn between A and E on this one. Is E wrong because it's too general? Since the stimulus refers to "a vast ocean region," it implies that specific ocean region, so one can't infer anything about all bodies of water (because for ex. some bodies of water may not have plankton or plank...

I think it's not a flaw because the stimulus says, "most long term friendships began because someone felt comfortable approaching a stranger." So people could approach strangers when they're not comfortable with it, but those approaches won't result in friendship, so it wouldn't affect the...

Ah, that makes sense now. Thank you for the explanation! Good advice about having to "work" to make an answer do something.
