At Duke University,Tim Wilson and Patricia Linville (1982,1985) recruited first-year students who were concerned about their academic performance.Students in the experimental group received statistics on grade improvement over the course of college and saw videotapes of upper-year students who talked about the improvements in their grades after the first year.Compared to students who saw no statistics and no videotapes,experimental students improved their grades and were less likely to drop out.These impressive results suggest that

A) the statistics and videotapes prevented learned helplessness from setting in.
B) the intervention was successful in teaching students learning and study skills.
C) the intervention was effective because students' mood improved.
D) the intervention helped students see their lives more objectively.
E) statistics and videotapes distracted students from their academic problems.
