Transnational cooperation among corporations is experiencing a model renaissance among United States firms, even though projects undertaken by two or more corporations under a collaborative agreement are less profitable than projects undertaken by a singly corporation . The advantage of transnational cooperation is that such joint international projects may allow United States firms to win foreign contracts that they would not otherwise be able to win.
Which of the following is information provided by the passage above?

(A) Transnational cooperation involves projects too big for a single corporation to handle.
(B) Transnational cooperation results in a pooling of resources leading to high-quality performance.
(C) Transnational cooperation has in the past been both more common and less common than it is now among United States firms.
(D) Joint projects between United States and foreign corporation are not profitable enough to be worth undertaking.
(E) Joint projects between United States and foreign corporations benefit only those who commission the projects.
答案选C,我非常困惑。C说的是什么意思，我都不明白。

请高人帮我解释一下

这道题讲美国的国际间企业并购进入了一段复兴期，虽然企业并购并不见得真的能带来最大化利润，但是与外国公司合作它们能得到海外市场云云，

题眼是你要认识Renaissance 这个单词：文艺复兴

复兴就说明之前有过一个高潮，高潮之后又有一个衰落，现在又重新起来，现在起来的并没有超过之前。这就是C要讲的意思：之前有过高也有过低。

总之这个题目很变态，我查了字典方才明白。其他选项都不确切。
