34. In 1985 state border colleges in Texas lost the enrollment of
more than half, on average, of the Mexican nationals they had
previously served each year. Teaching faculties have alleged that
this extreme drop resulted from a rise in tuition for international
and out-of-state students from $ 40 to $ 120 per credit hour.
Which of the following, if feasible, offers the best prospects for
alleviating the problem of the drop in enrollment of Mexican
nationals as the teaching faculties assessed it?
A. Providing grants-in-aid to Mexican nationals to study in Mexican
universities.
B. Allowing Mexican nationals to study in Texas border colleges and
to pay in-state tuition rates, which are the same as the previous
international rate
答案是B，A为什么不对呢？OG的解释为
because the problem to be addressed is a drop in enrollment of
Mexican nationals at Texas border colleges, providing financial
incentive for Mexican nationals to study at Mexican universities,
as A suggests, would offer no prospect of alleviating the problem.
