a recent 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 articles conclusions?

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 unujsually high levels of enzyme K

imo E

Conclusion : K contributes to improved performance
Evidence : above avg level of K in lifters and sprinters

Did K help their performance or was it created as a byproduct of the performance ?

A says K 'affects' the performance. not 'improves'
B does not dispell the doubt above
C not sure exactly why this not a choice
D conclusion is about all strenuous activities
E dispells the doubt whether while taking the cited evidence have the levels of the body producing K on its own, as a byproduct of strenuous activiy, have also been accounted for.

E is an assumption that is being made. If the assumption is true the argument is strengthened. Hence E
