We hope the measures to control house prices,__________ are taken by the government,will succeed.填什么?as?

问题描述:

We hope the measures to control house prices,__________ are taken by the government
,will succeed.
填什么?as?

个人觉得是which.此题为非限制性定语从句,主干是We hope the measures will succeed.to control house prices为measures的后置定语,逗号后面的句子是对measures的解释说明,as做关系代词要指代整个句子,所以不行.
