20______,I suppose,and the housing problems for the low-income families could be solved.
A.If you double your efforts B.To make some more efforts
C.Some more efforts D.Making greater efforts
为什么选C不选A

首先 i suppose 是插入语,插入语可以划去,不影响句子成分.然后就很明显了.A的话多了个and.而且用will 不该是could.再者.努力也不该是你努力.你无法改变低薪家庭买房子的问题吧.
