根据第二段的内容可知，下列哪个数据自20世纪80年代中期以来出现了下降?
[A]联邦政府在R&D上的投入。
[B]企业在R&D上的投入。
[C]联邦政府在R&D的投入占GDP的份额。
[D]R&D总投入占GDP的份额。
【答案】C具体细节题
【解析】本题考查第二段的具体细节。第二段用一些数据表明了美国与其他国家相比在科研领域的优势在缩小。其中一个数据就是研发经费占GDP的份额，这是考量一个国家对于科研重视程度的指标。文中指出，尽管自20世纪80年代起，美国全国在研发领域的投资占GDP的份额基本持平，但是美国政府在其中所占的份额却在缩小。这说明在美国政府之外，来自私人领域的研发投资占的比重在上升。这一题有一定的迷惑性，关键就在于对“美国政府”投资和“总”投资，以及对“投资总额”和“投资份额”要加以区分。正确答案应该是[C]。
