University administrator: Graduate students incorrectly claim that teaching assistants should be considered university employees and thus entitled to the usual employee benefits. Granted, teaching assistants teach classes, for which they receive financial compensation. However, the sole purpose of having teaching assistants perform services for the university is to enable them to fund their education. If they were not pursuing degrees here or if they could otherwise fund their education, they would not hold their teaching posts at all.
Which one of the following, if true, most seriously weakens the administrator's argument?The administrator’s point is that teaching assistants are not really employees, because their teaching is supposedly just a way to fund their education. So the best weakener will show that the university is using them for
the university’s own staffing needs, not merely to help the students.
(A) The administrator is cognizant of the extra costs involved in granting employee benefits to teaching assistants
This does not weaken the argument. It says something about the administrator’s awareness, not about whether teaching assistants are truly functioning as employees.
(B) The university employs adjunct instructors who receive compensation similar to that of its teaching assistants
This is not enough. Similar pay does not show that teaching assistants should be treated as employees.
(C) The university has proposed that in the interest of economy, 10 percent of the faculty be replaced by teaching assistants
This most seriously weakens the argument.
If the university wants to replace faculty with teaching assistants to save money, that shows the university is using them as workers to meet its own labor needs, not merely as students receiving financial help.
(D) Most teaching assistants earn stipends that exceed their cost of tuition
This weakens the argument somewhat, because it suggests the work is not just for tuition support. But it is still weaker than C, which directly shows the university sees them as labor substitutes.
(E) Teaching assistants work as much and as hard as do the university employees
This is too vague. Working hard does not by itself establish employee status.
Answer: (C)
