There are two ways in which an athlete can maximize his performance on the field— by improving his physical stamina or by improving his mental stamina. Research has clearly shown that physical stamina is much more important than mental stamina in boosting an athlete’s performance. Thus, if an athlete is working at improving his physical stamina, he is doing the most he can to maximize his performance on the field.

Which of the following most strengthens the above argument?


(A) According to another research, when athletes with comparable levels of mental stamina compete on the field, the one with the higher physical stamina invariably comes out the winner.

(B) A combination of physical and mental stamina cannot boost the performance of the athlete any more than than physical stamina can by itself.

(C) Critics of the researchers mentioned in the argument claim that these researchers considerably overestimate the importance of physical stamina in maximizing the performance of an athlete.

(D) There are other aspects, apart from stamina, that also play a significant role in maximizing the performance of an athlete on the field.

(E) If an athlete focuses more on developing his mental rather than physical stamina, he is likely to perform poorly on the field.
