This is Main Point Question.
@ In his book, Lowe tried to explain his own argument of how Mayan has vanished based on available archaeological records, but the author states a big flaw in his assumption.
A) Although it is true that Lowe claims for this in a second paragraph, focusing too much on this too narrow-scoped to be a main point. Also, the author argues that his theory has a flaw, so it isn’t “successfully proved.”
B) He did create step-by-step account of the collapse, but the author doesn’t embrace his theory to validate the claim of “breaks new ground in solving”, but rather shows skepticism on the theory.
C) “successfully”? Nope. The author has a doubt.
D) Just because the author has a doubt, we can’t conclude that his theory is definitely wrong either. So, “does not accurately reflect” is too strong conclusion to draw.
E) “While ~ appears credible” makes a great introduction of possible validity, but latter half points out the author’s skeptical attitude. Starting with approval but ending with skepticism just as the author does. Correct
