Recall That Petty, Cacioppo, and Goldman Conducted a Study on Persuasion.Students

Recall that Petty, Cacioppo, and Goldman conducted a study on persuasion.Students were led to believe that a comprehensive exam might be implemented at their university.They were asked to read either eight weak arguments in support of the exam or eight strong arguments.In addition, some students were told that the exam would be initiated in the following year or in ten years, well after the students' graduation (presumably!) .Finally, the researchers varied the expertise of the source of the arguments-that is, participants were told the arguments were generated by a local high school class or by a prestigious "Commission on Higher Education." The researchers measured students' attitudes toward the exam.In the end, what was the main result of this study?

A) When students believed the exam would be implemented in ten years, the expertise of the source influenced their attitudes, but the quality of the arguments did not.
B) When students believed the exam would be implemented in the following year, the expertise of the source influenced their attitudes, but the quality of the arguments did not.
C) When students believed the exam would be implemented in ten years, the quality of the arguments influenced their attitudes, but the expertise of the source did not.
D) When students believed the exam would be implemented in the following year, both the expertise of the source and the quality of the arguments equally influenced their attitudes.
