II.7.Recent evidence appears to contradict earlier findings that suggested that those who are physically fit cope better with stressful real-life events. Of a group of healthy women, those randomly assigned to a ten-week program of aerobic exercises performed no better in laboratory tests simulating stressful situations than did the subgroup assigned to a program without exercise.
Which of the following, if true, provides evidence for determining whether physical fitness makes one react better to stress?
(A) Superior reaction to laboratory stress situations was found to be more prevalent among women than among men.
(B) Healthy men, after training six months in weight lifting, encountered fewer potentially stressful situations in the subsequent six months.
(C) Subjects following a regimen during which they perfected their skills in a variety of relaxation techniques found that their lives seemed calmer after they began the regimen.
(D) College students with previous high levels of stressful life events showed a markedly reduced reaction to such events after training in aerobics for six months.
(E) Subjects with a high level of self-esteem more often engaged in physical-fitness regimens than did a control group of subjects with average levels of self-esteem.
