这解释不对，题目已经写了eventually，所以往后的时间都算，关键还是在在校期间延长了

the problem with this argument is that it takes the observation that "the number of Kravonians enrolled in college has been growing steadily", and takes that observation to mean that the number of graduates is going to increase in proportion.

choice (b) attacks this connection -- if students are taking longer to graduate from college, then the increased enrollment doesn't necessarily mean that there will be any more graduates! it's just a symptom of the fact that students are staying in school for longer.

for instance, if students take 4 years to graduate from college and college graduates 1000 students per year, then (not counting dropouts) that college's enrollment will be approximately 4000 students.
if students begin to take five years to graduate from college, then that same college will begin to have an enrollment of 5000 students -- even if it graduates the same number (1000) of students per year.
