GWD-24-40.

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?

A.     The first is the position that the argument as a whole opposes; the second is an objection that has been raised against a position defended in the argument.

B.     the first is a claim that has been advanced in support of a position that the argument opposes; the second is a finding that has been used in support of that position.

C.     The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.

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

E.      The first is an explanation that the argument defends; the second is a finding that has been used to challenge that explanation.

答案D  但是我没有觉得整个ARGUMENT是在反对第一句话啊

先谢过

agree

科学家一般是在40岁前完成他们最有创造性的研究,因此一般的观点都认为是年纪大了导致创造力的流失.但是,有研究表明很多进入某一研究领域比其他同行要迟的科学家都是在40岁后完成他们最有创造性的研究的.因为在40岁前很多科学家已经在自己的研究领域逗留了至少15年了,而科学家40岁后很少再作出有创造性的研究不是因为年纪大了,创造力下降,而是因为他们在某一个研究领域花了太多时间

所以,很明显,整个argument是在反对第一句话提出的年纪大导致创造力的流失

你的理解不太準確

40岁后有创造力的科学家不是因为工作经验多,恰恰相反,是因为他进入这个研究领域较迟,所以在这个领域发挥创造力的时间较晚,而那些进入这个研究领域较早的科学家,他们创造力早就在他们进入这个领域后的一段时间内发挥完了
