33. GWD21-Q33:

One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream. Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled “SuperOXY,” that has extra oxygen dissolved in the water. Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs.

Which of the following, if true, would serve the same function in the argument as the statement in boldface?

A. the water lost in exercising can be replaced with ordinary tap water

B. the amount of oxygen in the blood of people who are exercising is already more than the muscle cells can absorb

C. world-class athletes turn in record performances without such water

D. frequent physical exercise increases the body’s ability to take in and use oxygen

E. lack of oxygen is not the only factor limiting human physical performance

TN15-33给的答案是C。狗狗里是D。

Bold:功能上说是为了说明含氧水useless 的原因。

应该选同样说明水无用的一个理由。这样看来是C。不过我是选错了倒退的，

请问一下NN的看法

尘未，我觉得只有B和way有关。网上有一种变体，正好答案和划线互换。

谢谢大荣。很有用啊。
我觉得意思上这两句是一致的，不过后来看function，我就联想到到上面说的句子功能了。

我也觉得是 B 如果没和氧气就多了，那喝了也没用是这个道理吧。刚查了下 TN15 楼主对错答案了吧答案是B。
