问题 Even though the exchange rate was high, we ______ from them.
选项 A、buy
B、must have bought
C、had to buy
D、had better buy
答案 C
解析 Had to buy shows past necessity to complement the unexpected result from even though. Choices (A) and (D) are present tense and not parallel with was in the previous clause. Choice (B) shows past certainty.
