Q39:

Which of the following most logically completes the passage?

On the whole, scientists do their most creative work before age forty, a tendency that has been taken to show that aging carries with it a loss of creative capacity. An alternative explanation is that by age forty most scientists have worked in their field for fifteen or more years and that by then they have exhausted the opportunity for creative work in that field. Supporting this explanation is the finding that ______.

1 the average age of recipients of scientific research grants is significantly greater than forty

2 a disproportionately large number of the scientists who produce highly creative work beyond age forty entered their field at an older age than is common

3 many scientists temper their own expectations of what they can achieve in their research work by their belief that their creativity will decline as they age

4 scientists who are older than forty tend to find more satisfaction in other activities, such as teaching and mentoring, than they do in pursuing their own research

                    5 there is a similar diminution of creativity with age in nonscientific fields, such as poetry and musical composition

I did not understand why choose B? not A ?

一个现象两个解释，问如何支持解释2。

解释2说之所以老年科学家不容易取得成果是因为他们干这行太久了，创意都耗尽了。B说那些老年还出成果的科学家其实刚进入他们研究领域不久，也就是说这些人还没有干这行太久。变相支持解释2。

问it指谁?
than is common 的比较句前后补全了是什么样的?is common的主语省了什么?


谢谢

怎么感觉B是像在削弱第二个解释的，第二解释说入行的太久了，筋疲力尽了，B说入行还不久。怎么支持呢？！

这题比较绕，参照OG12的117才看明白是什么意思：
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.
意思是说科学家没有成果不是因为年龄的原因，而是因为干了十几二十年太久了（是人都会干烦，爱因斯坦后来也不行了）

回到这题，B项：很多有成果的科学家是比较老的时候才入行的 = 他们在科学界干的不久，有热情出成果 --> 支持原文的explanation
over.
