A recent university study indicates that students who receive full scholarships tend to maintain higher grade point averages than do students who must take out loans or work to finance school. The survey concluded that scholarships enable students to achieve high grade point averages by alleviating the stress related to financial concerns and freeing up students' time to study more.
The study's conclusion depends on which of the following assumptions?
Students who take out loans maintain higher grade point averages than those who work to finance school.
Finance – related stress affects student performance in a manner similar to that of restricted study time.
Students who must work to pay for their studies cannot maintain high grade point averages.
High grade point averages were not the primary criterion upon which the scholarship awards were based.
Controlling stress levels is less important to student performance than is intensive studying.
The correlation implied by the question is 'the lower the financial stress, the higher the grade point average.'
As always in verbal, we proceed by process of elimination:
(A) This is totally out of scope - it doesn't address the conclusion of the argument which concerns the higher GPA's of scholarship students
(B) This is also out of scope - this answer like A is concerned primarily with differences between those who work and those who take out loans
(C) This answer addresses the conclusion and not the premise, so it is unlikely to be the assumption hidden in the premises
(D) This seems the best so far at first glance. A closer look reveals that it is probably the answer: If students received scholarships because of their high GPA's and failed to earn scholarships because of their low GPA's, continued performance at the same level could be an explanation of the discrepancy
(E) Again this is out of scope
Thus, the best answer is D.
