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 weightlifters 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 weightlifters more than it helps sprinters.
(E) Strenuous activities do not cause the human body to produce unusually high levels of enzyme K.
