Q12

[clarafok]

hello,

i'm really confused as to why the answer is C. doesn't C mean that the passage needs to have info on how major volcanic eruptions do have different effects on regional temperature? or does it just need to make no mention of discernible effects?

and i kind of get why E is wrong but at the same time i don't really. is it because line 32-37 says that major explosions caused only a small drop in avg. temperature that i was supposed to infer that minor eruptions have no discernible effect in the opposite hemisphere?

thanks in advance!

Thanks for your question!

Remember, here we're looking for the claim for which the passage offers the LEAST support.

(C) is correct because the passage does not support the claim that major eruptions have no discernible effect on regional temperature -- it says the exact opposite! Even though the effect is smaller than previously thought, we still know that major eruptions cause a drop in temperature. So there is a discernible effect. (Discernible doesn't mean "different," it means we're able to point it out.)

(E) is incorrect because the passage explicitly states that "minor eruptions have no discernible effect on temperature." So forget about the hemisphere part; they have no effect, period.

Does that answer your question?

For this one, I chose (A) because I took the main idea of the passage and applied it to this question.

However, upon further review, is (A) wrong because the information in the passage does provide support for it in Paragraph 1 (that the author later tries to disprove)?

Thanks!

A is wrong because between line 30-37: Minor eruptions have no discernible effect; but major one does- smaller than expected but discernible.

Hi, could someone explain why the part of the passage that says a major explosion causes 'a smaller than expected in the average temperature in the *hemisphere (northern or southern) of the eruption*" -- doesn't eliminate A that says the discernible effect is on 'global temperatures'.

(I understand why C is correct... just not how to eliminate A)

thanks!

Sure! I believe the text you quoted is a fair way to eliminate answer choice A. If it causes a smaller temperature drop than expected, that's still a discernible effect, so A has some support and can be eliminated.
