Professor Smith published a paper arguing that a chemical found in minute quantities in most drinking water had an adverse effect on the human nervous system. Existing scientific theory held that no such effect was possible because there was no neural mechanism for bringing it about. Several papers by well-known scientists in the field followed, unanimously purporting to prove Professor Smith wrong. This clearly shows that the scientific establishment was threatened by Professor Smith's work and conspired to discredit it.

Which one of the following is the central flaw in the argument given by the author of the passage?
(A) The author passes over the possibility that Professor Smith had much to gain should Professor Smith's discovery have found general acceptance.
(B) The author fails to mention whether or not Professor Smith knew that the existence of the alleged new effect was incompatible with established scientific theory.
(C) The author fails to show why the other scientists could not have been presenting evidence in order to establish the truth of the matter.
(D) The author neglects to clarify what his or her relationship to Professor Smith is.
(E) The author fails to indicate what, if any, effect the publication of Professor Smith's paper had on the public's confidence in the safety of most drinking water.

A) The professor may have had much to gain, but what did the others have to lose?
B) Professor Smith's knowledge about the existing theory is not significant to the argument.
C) The answer. "Several papers by well-known scientists in the field followed, unanimously purporting to prove Professor Smith wrong. This clearly shows that the scientific establishment was threatened by Professor Smith's work and conspired to discredit it." The other papers may have been publishing the correct results! There is nothing to support the author's 'conspiracy theory'.
D) he was Professor Smith's great-great-grandfather... how does this matter!
E) Public opinion and confidence not being discussed.

B it is.

D and E are out.

A is out since nobody talked about any gains.

C is out. No evidences have been discussed.

Only an existing theory is mentioned. So, unless he presents evidences in the support of his paper, nobody is going to believe him. So, did he even know of the existing theory? Because if he did and still didn't provide any eveidence for his conlusion, he is a fake

Premises: Professor Smith published a paper arguing X. Scientific theory says that X isn't possible because of Y Papers followed to prove X is wrong.

Conclusion: scientific establishment was threatened by Professor Smith's work and conspired to discredit it. whats wrong here?

(A) should find acceptance or not... it is already been rejected, so have to explain that and not some hypothesis... if-> then

(B) knew or not... the Professor already published and bunch of the stuff followed, so it is irrelevant

(C) correct, all is mentioned is that everyone shouts X is wrong... no explanations or support to Y

(D) relationship? thats out of our interest

(E) we don't need public here at all... the issue is whether X is truth or not

C strongly holds

This one looks like C - its the only one that shows the author ignoring a specific side of the argument.
