The brain finds it best to keep smell receptors( )for unfamiliar and emergency signals such as the smell of smoke,which might indicate the danger of fire.

A.available
B.reliable
C.identifiable
D.suitable

答案:A
解析:
空格之后出现了for一词,由于B.reliable和C.identifiable通常不与for搭配使用,因此这两个选项可以排除。而D.suitable一词虽然能与for连用,但这里讨论的并非气味接受器与不熟悉或紧急的信号之间是否适配的问题。因此,本题的正确选项是[A]。
