-that's just_most of the students still have doubt.
A.what
B.why
C.where
D.how
答案是C 呀，为什么

correct answer: A

The students have doubt on Newton's Second law of Motion, therefore, what does the students have doubt on? A is the correct answer : that's just what most of the students still have doubt.

可分为两句话来看：
我想请物理老师解释一下她昨天教的牛顿第二定律。
这个牛顿第二定律就是……
A 学生们疑惑的东西；
B 学生们疑惑的原因；
C 学生们疑惑的地点；
D 学生们疑惑的程度。
“jx1115”解释地比较清楚。疑惑什么？疑惑“牛二定律”这个东西呗！所以选A。

What 这里应该是替代前面的那句....是做Doubt的宾语

D
