QUESTION TYPE: Necessary Assumption
CONCLUSION: We should raise tuition.
REASONING: Low tuition might be the cause of our problems.
ANALYSIS: The president gets ahead of himself. He says that low tuition might be the cause of the problem. By the end of the argument he’s convinced himself that low tuition is the cause of the problem.
For the negations, I haven’t used a narrow, grammatical approach. A negation is really just “anything the statement says is false.” Take a look at what I did with answers D and E, for example. Those are negations, but it’s obvious they cause no harm to the argument.
- CORRECT. The negation of this answer destroys the argument.
Negation: The low tuition explanation doesn’t apply in this case.
- We’re not concerned about actual quality. We’re concerned with what parents think determines quality.
Negation: Quality doesn’t depend on tuition.
- The president didn’t say that tuition is sufficient. He said we need to raise tuition. That’s a necessary condition. The president doesn’t need to assume that raising tuition is also a sufficient condition.
Negation: An increase in tuition might not lead to a larger applicant pool.
- Tempting, but it doesn’t matter if there are additional explanations. Those explanations could be wrong. It only matters if the president’s explanation applies.
Negation: There exists another, really stupid explanation for low enrollment: Evil clowns are frightening away prospective students.
- The president is talking about the overall level of tuition. It doesn’t matter if it’s gone up a bit. It only matters how high tuition is compared to other universities.
Negation: Tuition has increased $1 in recent years.
