D. Prospects of academic accomplishments.

【答案】1.C 2. A

【解析】

1. 考点出处：第一段While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job.

文章首句提到这在很大程度上是一条单行道，接下来谈到同时，大学研究人员去工商业界碰运气很普遍，但是向反方向走的却很少。这里的反方向指的就是工商业界去大学工作，由此可知，作者是想用单行道来描述很少有实业科学家去大学工作这一现象，故答案为C。

2. 考点出处：第二段Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions.
