### HideShow timer Statistics

Chronic fatigue syndrome is characterized by prolonged fatigue, muscular pain, and neurological problems. It is not known whether these symptoms are all caused by a single virus or whether each symptom is the result of a separate viral infection. A newly synthesized drug has been tested on those who suffer from chronic fatigue syndrome. Although the specific antiviral effects of this drug are unknown, it has lessened the severity of all of the symptoms of chronic fatigue syndrome. Thus there is evidence that chronic fatigue syndrome is, in fact, caused by one virus.

The argument assumes which one of following?

(A) All those who suffer from prolonged fatigue also suffer from neurological problems.
(B) It is more likely that the new drug counteracts one virus than that it counteracts several viruses.
(C) The symptoms of chronic fatigue syndrome are dissimilar to those of any other syndrome.
(D) Most syndromes that are characterized by related symptoms are each caused by a single viral infection.
(E) An antiviral medication that eliminates the most severe symptoms of chronic fatigue syndrome thereby cures chronic fatigue syndrome.

B. Links the effect of the drug to the fact that the virus may actually be caused by multiple viruses.

I believe it's E.

B is actually not the assumption, it's the conclusion of the argument.

consider the following part of the argument :

Although the specific antiviral effects of this drug are unknown, it has lessened the severity of all of the symptoms of chronic fatigue syndrome. Thus there is evidence that chronic fatigue syndrome is, in fact, caused by one virus.

it tells us that the author believe that since the symptoms are lessenned, the disease is cured. The very last sentence confirms that the author believes that the disease is cured.

I agree with B.
In E we are talking about 'severe' ,which is not right.

well, the last sentence gives the clue - "lessens the severity". So, I think it's E.

andr359, please post the OA and OE whenever you think we have enough replies.

(C) The symptoms of chronic fatigue syndrome are dissimilar to those of any other syndrome.

Other syndromes could have similar symptoms and the drug could very well have lessened those syndromes. Hence the passage is making the assumption that the symptoms lessened by this new drug are unique to the chronic fatigue syndrome.
