Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual. Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies' finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.

In the argument given, the two portions in boldface play which of the following roles?

正确答案： D:The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.

论点1：40岁之前的科学家更有创造性
论据：老了，没创造力（暗示40岁之后没有了）
however，转折
出现新观点（黑体1）：：40岁之后更有创造力，大部分他们进入这个领域要比之前晚。
对于新观点的解释（黑体2）：科学家们40岁以后少创意的原因，是他们在研究领域待的时间太长了，而不是因为年老了。
首先要明确的是文章中最终的argument是什么：黑体2是argument，反对的是论点1，黑体1是支持黑体2的，而不是challenges，
黑体2不是结论
