For nearly a century, physiologists erroneously believed that a buildup of lactic acid in muscle tissue was responsible for the soreness that many people experience after strenuous exercise. The acid, they claimed, is the waste produced by metabolic activity in the muscle and reaches “threshold” levels, causing soreness, when the muscle has depleted its oxygen supply. Researchers have recently discovered, however, that lactic acid is actually the fuel that powers muscular activity. Therefore, the cause of muscle soreness remains unknown. In the argument above, the portions in boldface play which of the following roles?

A) The first is an assertion that the author accepts as true; the second is a consideration in support of that assertion.

B) The first is an assertion that the author accepts as true; the second describes a situation that the author posits as contrary to that assertion.

C) The first is an assertion that the author argues against; the second is evidence presented as contrary to the author’s argument.

D) The first is evidence that the author believes is no longer valid; the second is additional evidence that the author uses to support his main point.

E) The first is a claim that the author believes to be invalid; the second is the author’s main point.

"erroneously believed..." foreshadows how the first boldface part is something that will be disproved, so A and B are out. The second boldface is evidence that leads to the conclusion so C is out. E cannot be correct because the last sentence is the conclusion (keyword: Therefore). Answer is therefore D.

I chose C, because I did not notice the words "as contrary to the author's argument".

A and B are wrong because of the word "erroneously" so the author does not accept it as true.

E is wrong because second is not the author's point, but just evidence to support that point.

I thought that D is wrong because First is not evidence, but a belief (or opinion). The second is not additional, but the only evidence to support author's conclusion.

Nevertheless, since C is wrong, D is the only option, not the best one IMO.

"as contrary to the author's argument"

That would make (c) wrong. The second bold is in the section that goes more along with what the author is arguing for. Not against.

It's contrary to the first point, but not contrary to what the author is trying to say.

I went with D because of the second part of the boldface but can please someone explain to me how the first boldface is an Evidence?
"Scientists believed that...". I mean people can believe anything the want to, there is no clear evidence that this is established.
Is it that we chose D because it is the only one with a correct second bf?
