Hi Team - may I know why Answer Choice D is incorrect given that the passage provide concrete examples to support the volcanic eruption theory?

Many thanks!

Hi Christine!

You're correct that the passage provides examples to support volcanic eruption theory, but answer choice (D) says those examples are 'in support of the more general assertion that theories must often be revised in light of new evidence.' The author of the passage is not intentionally using these theories to argue that revising theories in general is important (there's no evidence of this in the passage), rather, the author is saying that the volcanic eruption theory is the most applicable theory of the three. To put it simply, (D) is only partially correct and misstates the author's primary concerns! The correct answer must be fully accurate, so we can eliminate (D)!

Answer choice (A) best illustrates the author's main focus: the three theories and why volcanic eruption theory is the best one!

I hope this helps :)
