A study of class payments for a local art studio found that individual painting classes students paid for directly had a cancellation rate of less than five percent, while those who signed up in advance for a twelve-class package had a cancellation rate of more than 25 percent. This might have been caused at least partially by the fact that the more aware students are of the cost of a course, the higher the chance that they will attend.
Which of the following would, if true, best serve as an alternative explanation of the results of the study?
A. The price per class was slightly less for those who bought all twelve classes in advance.
B. Many students of the painting class believed strongly that they should support the art studio financially.
C. Those who attended all twelve classes were offered a partial refund.
D. Typically, students who paid for individual classes did so on the same day of the class that they attended.
E. Students who arrived just before class started could not be guaranteed seats with good views of the teacher.

This first sentence: "A study of class payments for a local art studio found that individual painting classes students paid for directly had a cancellation rate of less than five percent, while those who signed up in advance for a twelve-class package had a cancellation rate of more than 25 percent."
could easily be a Sentence Correction problem. There's a parallelism error on either side of "while", and the last clause is nonsensical -- "those who signed up in advance had a cancellation rate of 25%" means that the students had a high cancellation rate, which is meaningless. They're trying to say that the classes had a high cancellation rate.
The argument as written also has no justification at all, because it's never explained why people paying in advance would be less aware of the cost of the course than people paying individually. So there's nothing that would lead us to conclude that when students are "more aware of the cost" they are "more likely to attend", because we have no idea in which circumstance students are more aware of the cost.
That doesn't much matter if we want an alternative explanation for the high cancellation rate, which D provides: if people buying classes individually are showing up on the day of the class and signing up, they're already there. They don't have much time to cancel, and it certainly can't be true that they get a job in another country, say, in between paying for a class and attending it. So that would adequately explain why they don't cancel very often. Almost none of the other answers even explain why buying in advance might differ from buying individually, so most other answers can be ruled out instantly.
