Passage Summary: The price for a single college class hasn't changed in four years, yet students who used to be able to afford the school now say they can't pay for it.

Reasoning: N/A.

Analysis: The paradox lies in the conflict between a stable 'price per course' and a decrease in 'affordability' for the students. To resolve this, we need a factor that increases the total cost or decreases the students' available funds. Perhaps the university now requires more courses to graduate, or maybe the cost of housing has skyrocketed. Since this is an 'EXCEPT' question, four choices will offer a plausible explanation for why it's harder to pay, while the correct answer will be irrelevant or even deepen the mystery.
