### HideShow timer Statistics

A nutritionist studying the effects of massive doses of vitamin C found that of a group of 600 people who regularly took 1,500 mg of vitamin C daily for a year, fewer than 9 percent suffered serious cases of flu; of a group of 600 people who took 250 mg of vitamin C (the standard recommended daily allowance) daily for a year, 34 percent suffered at least one serious case of flu; and of a group of 600 people who took no vitamin C for a year (other than that found in the foods in a balanced diet), 32 percent suffered at least one serious case of flu.

Which of the following hypotheses is best supported by the evidence above?
(A) The effectiveness of vitamin C in preventing serious cases of flu increases in direct proportion to the amount of vitamin C taken.
(B) Vitamin C is helpful in preventing disease.
(C) Doses of vitamin C that exceed the standard recommended daily allowance by 500 percent will reduce the incidence of serious cases of flu by 25 percent.

(D)

(C) is wrong because it enforces that flu were due to deficiency of flu.

That is truly a tough question.
I would go for E.

Reasons:

A : The third fact that only 32% of the ppl suffered chances even though they did not consume any additional C vitamin disporves this theory

B : Too general a statement

C n D : Only a part of the para supports this hypothesis.

E : again, seems a bit too general. But, I would like to stick to this.

OA/OE Plz.

(A) The effectiveness of vitamin C in preventing serious cases of flu increases in direct proportion to the amount of vitamin C taken.
-Not supported by the argument. A higher percentage of people who took more than 250mg got a serious case than those who took no vitamin C.

(B) Vitamin C is helpful in preventing disease.
-We're talking about the flu, not all disease.

(C) Doses of vitamin C that exceed the standard recommended daily allowance by 500 percent will reduce the incidence of serious cases of flu by 25 percent.
-Not supported.

(D) Massive doses of vitamin C can help to prevent serious case of flu.
-Supported by the argument. Massive doses CAN help but don't guarantee prevention.

(E) A balanced diet contains less than 250 mg of vitamin C.
-The argument is about vitamin C and flu. Not about a balanced diet.

Why is C wrong??

This is supported by the argument => Doses of vitamin C that exceed the standard recommended daily allowance by 500 percent will reduce the incidence of serious cases of flu by 25 percent

daily allowance is 250mg. So if this amount is increased by 500 percent, it will be 1500mg. The incidence will be reduced from 34% to 9%.

=> That is correct? Why is not supported?

Thanks.

My best guess why C is wrong is, you cannot subtract 34 and 9% because the 9% is for serious cases of flu and 34% is for alteast one serious case of flu

I would choose D.

I think C is wrong because it says "will reduce the incidence of serious cases of flu by 25 percent", meaning that if we have a total population of x individuals, with the standard recommended daily allowance we have 0.34*x cases of flu. If we reduce this by 25% we have 0.75*0.34*x=22.5% that is a lot more than the 9% in the argument

Well my choice is E. Here goes my reasoning.

Choice D is strong statement to choose. It indicates that Massive doses of vitamin C can help to prevent serious case of flu. Furthermore in the argument it is mentioned that when a group takes 1500 mg of vitamin C, fewer than 9 percent suffered.

Choice B same reasoning too strong statement. Vitamin C is helpful in preventing disease.

Choice A is wrong as in the passage when the people start taking 250 gm of vitamin C, 34 percent suffered at least one serious case of flu.

Choice C is wrong and well explained by ranga.

Well after giving a careful thought i came to another conclusion which is different from my last post.

In case if we think that balanced diet contains more than 250 mg of vitamin C and we can do so because it is nowhere mentioned in the paragraph that it is less than 250 mg.

In that case choice E is wrong.
Choice D is wrong as last group who takes balanced diet (more than 250mg of vitamin C) also have less number of serious cases.

Choice C is wrong, see ranga post.

Choice B is strong statement as it is not fully able to eradicate the disease.

Choice A is correct in that case.

What is OA? I doubt whether this question is of ETS Quality?

A) The effectiveness of vitamin C in preventing serious cases of flu increases in direct proportion to the amount of vitamin C taken.

IF more Vitamin C is needed to reduce FLY, than the argument is weakened.

(B) Vitamin C is helpful in preventing disease.

Who cares what do vitamin C do in general ? OUT

(C) Doses of vitamin C that exceed the standard recommended daily allowance by 500 percent will reduce the incidence of serious cases of flu by 25 percent.

and? If they reduce by 25%, 30% or 50%, Who cares?

(D) Massive doses of vitamin C can help to prevent serious case of flu.

IF more vitamin C is needed to prevent serious case of Flu, than it is totaly true, than those who took 1500mg suffered less FLu than the others.

(E) A balanced diet contains less than 250 mg of vitamin C.
and? who cares how much Vitamin C contains a balanced diet ?
