问题 ______ these questions may sound academic, answers to them could have profound economic and political significance.

选项 A、Since
B、Although
C、Unless
D、Lest

答案 B

解析 在although引导的让步状语从句中,当从句主语和主句中的主语一致,而且从句谓语又包含be时,常用省略结构,如:I went on talking,although(I was)continually interrupted by him.虽然他不时地打断我的谈话,但我仍继续讲下去。
