39. GWD17-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

   Answer: D   B这个否定了前一个解释，但是不明白怎么支持了后一个？

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

 

Scientists are not as productive beyond age of forty as those under it, and such phenomena could be either explain by like loss of physical creative capacity or by the exhaustion of their creative opportunity, he soft knowledge in their brain.

 

Supporting this explanation is the finding that ______. This is asking for an evidence improving the second explanation, that is, the exhaustion of their creative opportunity contribute to their lack of productivity beyond age of forty.

 

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

 

This evidence has met both condition of the second explanations: 1) they are beyond age of 40 2) enter the field late therefore they have not exhausted their creative idea.. Meet both criteria, those scientists who are still very productive offer a proof of the second explanation.

 

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

 

If the scientist who diverge their concentration, focus on teaching and mentoring, and gain more satisfaction from such activities, they would not do much productive research. Ther alternative explanation say that if the scientists’ productivity are more related with the creative opportunity rather than the creative capacity. So, it must show they are productive even beyond age of forty and still doing creative work, their unusually late entrance into the field explain that they have not exhausted their creative opportunity.
