In the figure above, if x and y are each less than 90 and S // QR, is the length of segment PQ less than the length of segment SR?

(1) x>y

(2) x+y>90

上面这道题，参考答案是 A，可是我觉得这个答案有问题。因为在条件（1）下，当 90>x>y 时，PQ<SR；可是当 y<90，180>x>(180-y)时，PQ>SR。

所以这道题的正确答案应该是 E：Statements (1) and (2) TOGETHER are NOT sufficient.
