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 signif-
icantly 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.
今天发现我同学书上有道这题 大家说说答案是什么呢?难道是B么??为什么呢??
下边这道答案怎么是B呢?
In Kantovia, physicians’ income comes from insurance companies, which require
physicians to document their decisions in treating patients and to justify deviations
from the companies’ treatment guidelines. Ten years ago physicians were allowed
more discretion. Most physicians believe that the companies’ requirements now
prevent them from spending enough time with patients. Yet the average amount of
time a patient spends with a physician during an office visit has actually increased
somewhat over the last ten years.
Which of the following, if true, most helps to resolve the apparent discrepancy
between physicians’ perceptions and the change in the actual time spent?
A.  atients are more likely to be in a hurry nowadays and are less willing to
wait a long time to see their physician.
B. hysicians today typically have a wider range of options in diagnosis and
treatment to consider with the patient before prescribing.
C. hysicians are increasingly likely to work in group practices, sharing the
responsibility of night and weekend work.
D. Most patients would rather trust their physicians than their insurance
companies to make decisions about their treatment.
E. Since the insurance companies pay physicians a set amount for each
office visit, it is to physicians’ financial advantage to see as many
Patients as possible.
