PrepSC (findjuhl整理)- 26题 文法求助，谢谢!

26. The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.

A.    to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs

B.     to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing

C.     is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs

D.    is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs
                

E.     is the world’s smallest network digital camcorder, the length of which is that of a handheld computer, weighing

A: unveiled后面的从句没有谓语what应该做claims后面的成分，to be跟what重复了；the length is the length不通；it指代不明，可以指company

B: which 指代world不对，weighing 修饰对象有歧义，可能computer，可能company，都不对

C: which 指代world不对；it指代不明，可以指company

D: correct

E: the length is the length不通；weighing 修饰对象有歧义，可能computer，可能company，都不对

请问答案D的main clause不是有两个Verb (has unveiled 以及
                is) 的文法错误? 还是我对句子分析有问题? What it claims 中的claims 词性也是Verb.没错吧?

麻烦分析一下，谢谢!!

顶,同问,麻烦好心的NN讲解一下,

顶,麻烦好心的NN讲解一下,

The electronics company has unveiled what (it claims) 
            is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs
                    
            

The main structure here has only one verb, which is "unveiled", "is" is the verb of the clause. 

这题目GWD 中N多人说是B,终于ETS 给我们响亮的答案

谢谢 mbz,

之前还一直不清楚what it claims is 怎么分析

     (what it claims ) is       ,      再问 ,这样可以吗

答:不可以

I know what you said, thank you.
