(A) This directly supports the argument by providing evidence that states that reduced education funding experienced the predicted outcome: a decline in future income tax revenues. This confirms the negative economic consequences of cutting funding for higher education.
CORRECT(B) This weakens the argument by suggesting that maintaining education funding might not solve the budget deficit problem, but it doesn’t address the main concern about future tax revenues.
INCORRECT(C) This is irrelevant to the argument, as it discusses situations where funding is not cut but tax revenues still decline. It doesn’t address the impact of cutting education funding on tax revenues.
INCORRECT(D) This is a neutral statement. While it expands the scope of the problem, it does not strengthen the argument about the long-term economic impact of cutting education funding.
INCORRECT(E) This doesn’t strengthen the argument, as it focuses on the magnitude of the budget deficit, not on the specific consequences of cutting education funding.
INCORRECTAnswer A.
