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

答案就是A，Prep的解释是说, more than...做同位语修饰20 percent of the world's fresh water

但是我怎么觉得这个同位语的比较对象看不出来是不是对等啊，是不是more than省略了什么东西呢？望大家指教

Hi All,

Following is one of the right answers of GMAT Prep question:

Can someone please help me understand how the following comparison is complete. Don't we need "that of" before "all" to complete the comparison.

===========================================
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.
==============================================

There are some examples in OG where it clearly say that in order to complete the comparison we need to have that/those. Can some one please tell why the same is not the case here ?

=============================================

The original question is copy pasted below for quick reference. The OA is "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.

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.

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.

We would have used the relative pronoun "that" to refer to fresh water, if we were comparing fresh water.. Here the case is that we are not comparing fresh water capacity of lake baikal with that of other north american lakes..

we are just comparing the total capacity of lake baikal.. its a special quality of lake baikal tht it holds fresh water...

Let's say the total number of litres of the world's fresh water = 100
then Lake baikals capacity out of hundred = 20
Let's say that total capacity of north american lakes = 18

Now all we are saying is that "More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 litres of fresh water, more than all the North American Great Lakes combined.

and so you can see that we don't need to use the relative pronoun..

yeah, ok, i see what you're saying. that's a very good question.

here's what's going on here:
"more than all the North American Great Lakes combined" is actually a MODIFIER of "20% of the world's fresh water", which is WITHIN the first MODIFIER. therefore, it's a SUB-modifier, so to speak.

let me try to illustrate it graphically:

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)).

the blue modifier modifies stuff that's inside the orange modifier, so it falls within the orbit of the orange modifier; it MUST be removed if the orange modifier is removed (because it has nothing left to modify).

let me know whether this makes sense.

orange and blue: go gators!
