The cost of a semester' s tuition at a certain university is based on the number of courses in which a student enrolls that semester. Although the cost per course at that university has not risen in four years, many of its students who could afford the tuition when they first enrolled now claim they can no longer afford it. Each of the following, if true, helps to resolve the apparent discrepancy above EXCEPT: ['The university awards new students a large number of scholarships that are renewed each year for the students who maintain high grade averages.', 'The cost of living in the vicinity of the university has risen over the last two years.', 'Faculty salaries at the university have risen slightly over the past four years.', 'The university has turned many of its part- time office jobs, for which students had generally been hired, into full-time, nonstudent positions.']
