prep-33 迷惑啊,感觉有两种理解,跪求解决

(B) With 20 percent of the world's fresh water, that is more than all the North American Great Lakes combined, Siberia's Lake
                Baikal has more than 300 rivers that drain into it.

(C) Siberia's Lake
                Baikal, with more than 300 rivers draining into it, it holds more of the world's fresh water than all that of the North American Great Lakes combined, 20 percent.

(D) While more than 300 rivers drain into it, Siberia's Lake
                Baikal holds 20 percent of the world's fresh water, which is more than all the North American Great Lakes combined.

(E) More than all the North American Great Lakes combined, Siberia's Lake
                    Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.
            

答案是选a, 其他答案为啥错, 我知道, 但是我个人觉得a 答案有两种理解, 希望大家可以帮忙指正, 先谢了

1. which  指代lake b, 后面的more than 作同位语指代water,那么这样就是水跟水之间的比较了,这时的句子主干就是More than 300 rivers drain into Siberia's Lake
                    Baika

2. 因为which 是非限定的从句,这样就可以先省略(个人的一点愚见, 不知道对否,希望各位指正),  此时的句子主干是More than 300 rivers drain into Siberia's Lake
                    Baika more than all the North American Great Lakes combined,那么这句化的意思就是流到lake b中的300多条河比流到五大湖的河加起来还要多, 那句子就是河的数量之间的比较了

以上我个人的一些不解,有什么错误希望各位帮忙指正, 在下先谢了

望求解决,谢谢各位了

此题我对于prep破解版里有关E的解释一直耿耿于怀！

恳请大N指点！

A.More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh
            water, more than all the North American Great Lakes combined.

E.More than all the North American Great Lakes combined, Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.  将Baikal和北美5大湖直接进行比较,概念不对等,应该是Baikal的水量和五大湖的水量进行比较.

我的困惑在:如何看出E选项比较概念不对等？是我对句子结构分析的功力不够，导致看不明白吗？

强烈期待解答，叩谢！

如果按照答案的那种来理解的话, more than ....应该作同位语来修饰the world's fresh water

我个人觉得从More than all the North American Great Lakes combined, Siberia's Lake Baikal 可以看出比较对象是all the north american great lakes 和 siberia's lake baikal 之间的比较, 后面的其他more than....到结尾应该是作修饰语修饰silberia's lake baikal 的

个人的一点见解, 请指正

看的是逻辑修饰关系吧.more than all the North American Great Lakes combined应该修饰20%fresh water.

E错,因为more than all the North American Great Lakes combined,去修饰 Siberia's Lake
            Baikal.
