问题 The suggested causes of a given phenomenon cannot always be independently observed, and so it is hard to ______ the possibility of there being explanations alternative to the one proposed.

选项 A、account for
B、rule out
C、guard against
D、do with

答案B

解析 account for解释;guard against防备;do with可以用have/be to do with something“与某事有关”;上述三项,均与题义不符。rule out“排除……”,用在此句中,意思是“很难排除其他一些可能的解释”,意思通顺。
