### HideShow timer Statistics

Scientists typically do their most creative work before the age of 40. It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. However, a study has found that almost all scientists who produce highly creative work beyond the age of 40 entered their fields late and less than a dozen years before their creative breakthroughs. Since creative breakthroughs by scientist under 40 also generally occur within a dozen years of the scientistâ€™s entry into the field, the studyâ€™s finding strongly suggests that the real reason why scientists over 40 rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.
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 defends; the second is evidence that is advanced as part of that defence.
B. The first and second are both claims that have been advanced in support of a position that the argument as a whole opposes.
C. The first is an explanation that the argument challenges; the second provides evidence in support of a competing explanation that the argument defends
D. The first is an explanation that the argument challenges; the second is evidence that has been used against an alternative explanation that argument defends.
E. The first is an explanation that the argument defends; the second is evidence that has been used to challenge the explanation.

>>>Argument:the studyâ€™s finding strongly suggests that the real reason why scientists over 40 rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.
"aging by itself brings about a loss of creative capacity" Challenges the argument because scientists over 40 can be creative
creative breakthroughs by scientist under 40 also generally occur within a dozen years of the scientistâ€™s entry into the field
provides evidence to the first argument

C!

Had to choose between C and D. "alternative explanation" in D seems to be wrong.

Yes - one more for C. The fact that older workers take longer to produce creative work is not an alternative explanation but a competing explanation....
