以下摘自其他论坛,个人认为讲解的最清楚:this is a main idea question, and, at that, one of the tougher ones i've seen.
still, i find the following to be helpful: on MAIN IDEA QUESTIONS: ALWAYS ANSWER THE QUESTION IN YOUR OWN WORDS BEFORE LOOKING AT THE ANSWER CHOICES.
when i do that on this question, i get "the passage is primarily concerned with... (i said) ...showing, with a study, that an increase in patents isn't necessarily linked to an increase in creative output"
of the five choices, this is definitely closest to (c).

(a) is wrong because of the word "unanticipated", which isn't justified at all. the passage doesn't mention whether the semiconductor firms had anticipated the consequences of any of their patenting policies. for all we know, they knew perfectly well what would come of these policies. _________________ ron purewal

而且A项就算是 yielded unanticipated results,它的主语也应是Thesystem of patent-granting(首句主语),而不是the semiconductor industry’s approach to patenting(它只是文章中用来举例的细节)
