1.B.which to choose 疑问词+不定式在句中作know的宾语.
2.C.to live in 不定式作定语,live in the room,要加介词in

B
C

B.which to choose 我不知道选哪个 ,也可以用how to choose
C.to live in

1.B 不知道要选择哪个，又是陈述语气，所以应该是which to choose；
2.C live in the room，所以要加上介词in。

1.B.前面是twowords, 我不知道选择两个中哪一个，哪一个用which，宾语从句。选其他都是错误，也没法改。
2. C.to live in 不定式作定语，live in the room，住在房间里面，其他不对。
