问题：Agoodideaof______withtheseoldmag? 
A good idea of ______wh these old magazines came to her.A.what to do it B.how to do itC.how to do D.what to do 
回答：答案选d
因为what 跟 do with 连用，deal with跟how连用，所以根据这个我们可以排除b.c
what to do with中what 做do的宾语，所以do后不能跟宾语，所以如果用do it with的话就不缺宾语也就不能用what 来提问了，所以排除a
所以答案选d
