为什么'not for the speed and path of its movemtent？'不行

2. 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 fo u.s form products.
   答案为‘To establish tighter restrictions on the amount of grain formers will be allowed to grow and to encourage’，分不清主谓了，总觉的有两个谓语？

第一题是否看错了还是打错了，我觉得无论修饰谁都应当用its
第二题是考平行结构。是 sb try to do sth and to do sth.谓语就是try to do,后半句省略了try
第三题是不是选b,我是从简洁的角度考虑的。因为decline就有down 的意思了，我们一般只说decline to ...而不说decline down to

谢，1提的正确答案是‘not  the speed and path of its movemtent’，为什么不加 ‘FOR’？
    2提的‘WILL’是谁的谓语？

mike1999

gauge是及物动词啊，把该句省略部分补全就是not  gauge  the speed and path of its movemtent’.
will try 是some newly elected members 的谓语
