            final
            tryouts

            athletes'
            performance
            and
            toward
            their

            the

答案是E。

我想问的是，未划线部分“a
            complex
            4
            final
            tryouts
            are
            held for
            athletes
            representing
            the
            United
                    States
            in
            the
            Olympics”，a complex后面没有that，让我误以为a
                complex
                4
                final
                tryouts 是主语，马上对划线部分搜寻独立主格或者非限定性从句。

这算不算GMAC的bug啊？
