请教逻辑R-43

以下题的答案是Ｃ，用排除法找到答案，但是真不明白答案和原文有什么联系．

题目大致意思是跨国合作在美国公司中正经历一场复兴，多公司合作项目比单独一家做利润低，而好处是跨国合作允许美国公司赢得海外定单．．．

答案就读不懂了，为什么这就意味着跨国合作been both more common and less common
than it Is now among United States firms呢？

看了lawyer的分类分析也没找到更多的解释，只能求助大家了．

Transnational cooperation among corporations is experiencing a modest 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 single 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．

43．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 corporations are not profitable enough
to be worth undertaking．
(E) Joint projects between United States and foreign corporations benefit only those who
commission the projects．
