Psychologists conducted an experiment in which half of the volunteers were asked to describe an unethical action they had performed, while the other half were asked to describe an ethical action they had performed. Some of the volunteers, chosen at random from each of the two groups, were encouraged to wash their hands afterward. Among those who described unethical actions, those who washed their hands were significantly less likely to volunteer for another, similar experiment than those who did not wash their hands. The researchers concluded that some of the subjects failed to volunteer again in part because of their having described an unethical action.
Which of the following would, if true, most help to support the researchers' conclusion?
A) Among the volunteers who described ethical actions, those who washed their hands were significantly less likely to volunteer for another, similar experiment than those who did not wash their hands.
B) The average likelihood of volunteering for another, similar experiment was higher among those who described ethical actions than among those who described unethical actions.
C) Most of the volunteers who were encouraged to wash their hands did so.
D) The volunteers in the study were not more disposed to washing their hands under normal circumstances than the general population was.
E) Equal numbers of volunteers from both groups were encouraged to wash their hands.
