求解OG上面的一道题，小女子不甚感激~~

OG逻辑的T117.
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 of scientists who
produce highly creative work beyond the age of forty, a disproportionately large number entered
their ?eld at an older age than is usual. Since by the age of forty the large majority of scientists have been
working in their ? eld for at least ? fteen years, the studies’ ? nding strongly suggests that the real reason why
scientists over forty rarely produce highly creative work is not that they have aged but rather that scientists
over forty have generally spent too long in their ?eld.
In the argument given, the two portions in boldface play which of the following roles?
(A) The ?rst is a claim, the accuracy of which is at issue in the argument; the second is a conclusion drawn on
the basis of that claim.
(B) The ?rst is an objection that has been raised against a position defended in the argument; the second is
that position.
(C) The ?rst is evidence that has been used to support an explanation that the argument challenges; the
second is that explanation.
(D) The ?rst is evidence that has been used to support an explanation that the argument challenges; the
second is a competing explanation that the argument favors.
(E) The ?rst provides evidence to support an explanation that the argument favors; the second is that
explanation.

正确Answer是E，我就是不明白，argument challenges和argument favors有什么区别？就是C和E的差别在哪里？？
跪求——跪求——跪求......

做黑体字题，我会先扫一眼全文之后看黑体字部分作用。
1. 明显第二个部分是结论，
2. 然后找第一段黑体字与第二段。明显他们是同向的支持关系。
3. 排除到剩下C和E，看态度词发现C中第一段support what the argument challenge的，等于是challenge结论（第二段黑体字），与我们的判断不符合。
4. 选E
