A recently published article on human physiology claims that Enzyme K contributes to improved performance in strenuous activities such as weightlifting and sprinting. The Article cites evidence of above-average levels of enzyme K in Olympic weight lifters and sprinters.

Which of the following, if true,would most strengthen the article's conclusion?

a ) Enzyme K levels are the most important factor affecting the performance of strenuous activities.
b ) Enzyme K has no other function in the human body
c ) Enzyme K is required for the performance of strenuous activities.
d ) Enzyme K helps weight lifters more than it helps sprinters.
e) Strenuous activities do not cause the human body to produce unusually high levels of enzyme K

Its a tough one ! Please Post in your answers with the reasoning :wink:

Question stem is not provided. looking at the answer choices, I am assuming its a strengthening question.

Answer IMO: E as it rejects the possibility that the strenuous activities are contributing to high levels of the enzyme, thereby strengthening the articles conclusion that high levels of enzyme K enables weightlifters to perform their task. Cause-effect relationship.

Or it may be asking assumption.

I go with E as gmatpapa the author assumes that Vitamin K is the Cause not effect is the assumption here.

We need to eliminate any alternate explanations for the evidence given - "The Article cites evidence of above-average levels of enzyme K in Olympic weight lifters and sprinters"

What if strenuous activities cause above average levels of enzyme K and not the other way around? So we need to eliminate this possibility. In short we are strengthening the cause-effect relationship. So "E"

E. Strenuous activities do not cause the human body to produce unusually high levels of enzyme K

OA is E and the reason as gmatpapa and raptor explained are correct.

My Take:
Enzyme K has to cause improved performance in Strenuous activities and not Strenuous Activities causing high levels of Enzyme K . If the latter scenario is true, then the evidence weakens considerably as Enzyme K then plays no role in performance enhancement.

In C , it states that Enzyme K is required for Strenuous activities. However, in the stimulus it is only mentioned that Enzyme K helps in improved performance ( As a performance enhancement). So, Option C can be ruled out.

hope that helps ..

The answer is E. Cause - Effect relationship is not reversed.

Yeah, be careful about assumptions regarding causation in CR questions. Seems to be a fairly frequent gap in the logic.

Note : Added the Question Stem


E is the right answer,
focus on the claim you are trying to strengthen "A recently published article on human physiology claims that Enzyme K contributes to improved performance in strenuous activities"
A)in strengthen questions these type of answers are always wrong [the most important, or the most crucial...]
B)if K has no function, is not any help to the claim we are trying to support
C)some thing being required does not mean it contributes to improved performance
D)this is just a comparison of to group samples and does not support the main claim.
E)by showing that the relationship is not reverse b/w the to things [K and the strenuous activity] we are strengthening the claim that article present...

in strengthening questions it is important to take the answer choices as proven to be correct and the stimulus conclusion as suspect. so by using the answer choices you should see if which one being true could support the conclusion.

classic causal argument.

effect is not causing the cause here.
E mentions the same.

E.

Its a cause and effect reasoning. Author concludes that since people with high K undertake strenuous activities, K -> Improved performance in Strenuous Activities.

This can only be necessary if Strenuous Activities are not causing K to be high.

+1 E. If X then Y. So if not Y, then not X. cause and effect.

Nice question! E it is!

"Reverse causation" problem.

Enzyme K leads to more activity...rather than More activity producing more Enzyme K..
