University president: Our pool of applicants has been shrinking over the past few years.
Conclusion
If we want to increase the size of our applicant pool, we need to raise out tuition and fees.
Evidence
It's possible that the reason we've seen our pool shrink over the past few years is that we charge too little for tuition and fees, giving off the impression that we're not as high quality an institution.
Evaluation
Any time an author says , she's assuming - Y is actually a viable way of getting X - There aren't other ways of also getting X
So this author is assuming that (assuming it wouldn't turn even more people away).
Our author is assuming that .
And then there seems to be a Possible vs. Certain move in her argument, where she goes from "It's possible that X is the explanation" to "We'll have to do something about X".
Goal
Look for any of the three assumptions we've noted, or any other answer that, if negated, would make it sound like we don't need to raise tuition in order to increase our applicant pool.
