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.

 

Which of the following is information provided by the passage?  A  C

 

(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.

答案是C，C项里的both more common and less common是什么意思呢？A为什么不对呢？

搜了一下论坛，明白了
我也选错了A，实际上A是不能够从文章中推出的结论，文中只说吃独食比合作的项目更赚钱，并不能推出有项目是没法吃独食的，对吧。
但是C就不一样了。
