The administration at a certain university has explained this year' s tuition increase by citing increased spending on faculty salaries and on needbased aid to students. However, this year' s budget indicated that faculty salaries constitute a small part of the university' s expenditure, and the only significant increases in scholarship aid have gone to academic scholarships awarded regardless of need. The administration' s explanation is not believable. Which one of the following, if true, most strengthens the argument that the administration's explanation is not believable? ['Faculty salaries at the university have increased in line with the national average, and substantial cuts in government student-loan programs have caused financial difficulties for many students at the university.', 'Of the substantial items in the budget, the greatest increase was in administrative costs, facilities maintenance costs, and costs associated with the provision of athletic facilities.', "With this year's budget, the university has increased its total spending on scholarship aid by 5 percent.", "With this year's budget, the university increased the allotment for faculty salaries by 5 percent while tuition was increased by 6 percent."]
