Reaching the correct answer here requires understanding the principle (which is not explicitly stated) that the administrator applies to the premises to arrive at his conclusion.
(I will simplify the conclusion and premises for sake of clarity)
Conclusion: Graduate students don't deserve benefits.
Premise: They teach only for money. If they were rich, or studied at another university, they wouldn't be teaching here at all.
PRINCIPLE: We don't give employee status to such people. (We give employee status and the appropriate benefits only to the people who teach here for reasons more than just money.)
Now, the correct answer will have to show either
1. these teaching assistants are actually here for noble reasons other than just money (they admire the founder of the university or whatever the reason be)
or
2. show that the university does in fact hire as their employees people who work only for money.
None of the answer choices pertains to 1. so for get about it.
But (C) does exactly 2. Just to save some costs (in the interest of economy), the university is willing to hire these teaching assistants as their employees knowing that they would work only for money. This goes against their principle.
I do agree with everything you're saying about C, especially (1). As for (2), it's not needed to prove that the university hires, as employees, people who work only for money. We just need to prove that the university hires TAs for reasons
other than their "
sole purpose (enabling them to fund their education). The "TA's sole purpose" part of the premise makes the admin's argument vulnerable to any other reasons as to why the university would hire a TA.
Also, for anyone who chose D (like me), it's wrong because it helps the argument. Saying most TAs earn stipends that exceed their cost of tuition demonstrates funding of education. I initially thought that if stipends exceeded the extra cost of tuition, that could mean the salary exceeds beyond the funding of education. However, that's an extra assumption to make about the answer choice. D is not attacking the conclusion-premise relationship.
