9.When Congress reconvenes, some newly elected members from rural states will try and establish tighter restrictions for the amount of grain farmers are to be allowed to grow and to encourage more aggressive sales of United States farm products.
黄色的地方很不明白。。。
我觉得应该是定语从句修饰amount
但是定语从句至少要有个that 来当从句主语啊
这个地方怎么理解哇。。。我觉得五个选项都不对
　　A） and establish tighter restrictions for the amount of grain farmers are to be allowed to grow and to encourage
　　B） and establish tighter restrictions on the amount of grain able to be grown by farmers and encouraging
　　C） establishing tighter restrictions for the amount of grain farmers are allowed to grow and to encourage
　　D） to establish tighter restrictions on the amount of grain capable of being grown by farmers and encouraging
　　E） to establish tighter restrictions on the amount of grain farmers will be allowed to grow and to encourage（这里的will be allowed to grow 的主语是谁啊，这个结构很诡异啊，看不明白挖。。。。。。。。。。。。。。。）
答案选e

我觉得吧，A of B结构A应该是主语，就是amount
那个will be allowed 应该是定语从句，定从that是可以省略的，宾语从句的that最好不省略的
