(C) are geared to enhance
                athletes' performance and their preparation  ==》造成歧义，enhance their preparation.

关于B还有两个问题：

第一个有点低级，The Sports Medicine Programs of the Olympic Training Center，这个词组的核心词尽管用了复数，但是考虑到全部大写，我就理解成专有名词作为一个整体来看了，结果谓语动词选了单数。这种想法是不是绝对错误的呢？是不是无论是否专有名词，只要核心词是可数名词复数，谓语动词一律用复数？

第二个问题是，B如果谓语用了复数，是不是就正确了

不要想那么复杂，基本上有s就复数没有就单数，当然特殊的单复数形式除外

如果是are是对的

关于这道题，还有2个小问题：

1：同位语a complex where final tryouts are held for athletes representing the United States in the Olympics  不是在暗示前面是一个整体么？所以直接导致我选了单数谓语动词。关于这个NN能否给讲讲；

让我想起来一句话：40 students，a whole class，are going out for dinner. 这么写？

2：gare to，这个to 是借词吧？所以即使B改成are 是不是也不对呢？也就是gare的用法。

谢谢！
