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
A. the average age of recipients of scientific research grants is significantly
greater than forty.
B. 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.
C. 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.
D. 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.
E. there is a similar diminution of creativity with age in nonscientific
fields, such as poetry and musical composition.

OA is B.
A is the only way I can say is not the answer.
