So last night I took my final exam in " Public Opinion and American Politics " . It 's the shortest class I ' ve ever taken . It was during the first summer term , a six week class meeting for three hours , two times a week ( Tuesday and Thursday ) . So in total we had twelve class meetings .

Question: What may be the reason that they took the summer class ?
Answer: They needed it to graduate in the fall semester .They wanted to graduate in the summer .None of the above choices .It was convenient for them to take it in the summer .
