问题 ______ pollution control measures are expensive, many industries hesitate to adopt them.

选项 A、Although
B、However
C、Because
D、On account of

答案 C

解析 近义辨析。although虽然(多用于正式文体,语气较强,只用于表示事实的让步状语从句中,叙述的是已成立的事实);however然而(较正式,虽与but意思相同,但比but弱,且把相反的概念放到极为次要的地位,因此常常用来做插入语,还可较婉转地引出最后决定或结论);because是从属连词,多表示所叙述的理由是本句的重点,引导原因状语从句;on account of因为,由于(引导名词形短语,不能引导从句);所以C为答案。
