A Michigan State University student spends his summer months in his hometown, where he works for a local micro-brewery during the evening hours. In the late morning, he attends the local community college, where he takes a summer course that he knows will transfer back to MSU. Although he finds the courses just as challenging as his regular university, he does not worry about his summer grades affecting his 3.2 (out of 4.0) grade point average, because MSU only accepts the transfer credits. As long as he receives C grade or better, he maintains his current grade point average. Which of the following theories suggests that the student will only work as hard as necessary to earn a "C" grade?A) Expectancy TheoryB) Objective-setting TheoryC) Equity TheoryD) Maslow’s Theory
