We have two rooms _____ ,but I can't decide _____.
A.to live ;to choose which one
B.to live in ;which one to choose
为什么选B,不选A?

live 是不及物动词,后面必须加in 才能接 rooms.
which one to choose
这个是固定句式,是疑问代词which,what,where等加上to do构成,给你举个例子：i don't know what to do.(我不知道该做些什么）
know是动词,后面的which one to choose跟在它的后面做know的宾语.
which在宾语从句中做的是主语,次序不变,固定用法.
