is this a must be false?

[Luke Haqq]

Hi ashpine17!

Yes, this is a cannot be true/must be false question. With that type of question, four of the answer choices could be true or must be true, while the correct answer choice cannot be true/must be false.

Hi I am just confused as to why the answer is C and not E?

[Robert Carroll]

elishahasan18,

Answer choice (E) seems extremely well-supported by the third paragraph: "Mass and Portman found that minor
eruptions have no discernible effect on temperature." So, minor eruptions have no discernible effect on temperature. Answer choice (E) is a specific instance of that general claim, so seems true. That's not at all what we're looking for for this Cannot Be True question.

Answer choice (C) contradicts the rest of that paragraph, which is why it's the right answer.
