30日考试，我什么都不会--Question2

Og56

the army corps of engineers proposed building paralled to shore a breakwater of rocks that would rise six feel above the waterlin and act as a buffer, absorbing....and protecting...(这个是正确答案）

请问这里的absorbing and protecting refer to which one? buffer or a breakwater of rocks ?

其中有个错误答案

as a baby emerges form the darkness of the womb, its rudimentary sense of vision, which would deemed legally blind for an adult, would be rated about 20/500.

错误的原因是subordinate clause beginning with which is awkward and ambiguous

我怎么觉得没问题，which修饰前面一个vision不是挺好的，如果我想修饰its rudimentary sense因该怎么表达！

谢谢了，大哥们！！！！！！！

我再补从一个小问题，好比上面那种结构假设

句子+N(结尾），v+ing....

v+ing到底是修饰句子中的n,还是结尾的n

如果用句子+N(结尾），which。。。。很显然修饰句尾的那个

那牛们帮帮忙亚
