SC - Comparison Doubt

by goelmohit2002 » Sat Jul 04, 2009 10:39 am
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 [spoiler]"A"[/spoiler]

(not able to answer of your doubt)

It is unwanted

wrong comparison

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..
One love, one blood, one life. You got to do what you should.
