单选题 Young people tend to stay with their family longer on these days for accommodation is expensive but, when they move away to a job or college, there are various options open to them.
A. these days for B. during these days as
C. these days as D. within these days for

【正确答案】 C
【答案解析】在此直接用these days作为状语而不必加任何的介词,之后由主语accommodation引导的是原因状语,故用as才对。
