I was debating major time between A and E. However, E has the phrase with more than 300 rivers draining into it....GMAt does not prefer the structure in the form of " with ....+Verbing"

Also Lake B can not be more than all the North American Great lakes combined....It is the water in Lake B.

Hi Folks,
Meaning is very important in 600 +level SC questions

First in every SC question understand the meaning of the option A

In option A -clearly states Baikal ' fresh water is more than all the North American Great Lakes combined. here the meaning is logical

In option E- More than all the North American Great Lakes combined, modifies lake baikal but it should modify the baikal's fresh water.Option A does that clearly .Hence E wrong

Hope it helps

(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.
Option C is something like: "Siberia's Lake Baikal IT holds". The pronoun is not correct. Aslo "20 percent" is misplaced.

The problem with D is "while": it means -at the same time - or shows a contrast => in both cases it not correct in the sentence (none of the two things happens here).
(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 (initial modifier), Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.
E says that "Siberia's Lake Baikal is more than all the North American Great Lakes combined" => misplaced modifier

(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.
B says that "20% of the world's fresh water is more than all US lakes"

A is correct

Hello Experts,
Can someone please explain what the modifier "more than all the North American Great Lakes combined" is modifying? Is it modifying previous modifier or is it modifying the main clause. Of late, I have been seeing such constructions, and really want to understand how such constructions work.

Thanks

Dear Himanshu,
I'm responding to your pm, and I am happy to help.

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.

One way to think about it is: exactly what is "more than all the North American Great Lakes combined"? The Great Lakes, as lakes, are fresh water, so we are comparing them to another quantity of fresh water --- "20 percent of the world's fresh water", a noun phrase that is the object of the the noun-modifying phrase beginning with "more than all ..." Not surprisingly, the modifier touches the noun, in accordance with the Modifier Touch Rule. See this blog for more on that rule:
https://magoosh.com/gmat/2013/modifiers- ... orrection/
While there are exceptions to the Modifier Touch Rule, that's an exactly place to start to look for the noun modified.

Keep in mind that modifiers are a part of what the GMAT calls "Logical Predication" on the the SC ----- in other words, to make sense of whether modifiers are used correctly and what they are modifying, you have to look beyond the grammar of a sentence to the logic & meaning, which are more primary. See this blog for more on that:
https://magoosh.com/gmat/2013/logical-pr ... orrection/

Does all this make sense?

Dear Chiranjeevee,
I'm happy to help.

Here is version (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.
The main subject is "more than 300 rivers", and the main verb is "drain". Everything before the comma is the independent clause of the sentence. After that are just modifiers.
Does this make sense?

Going with the 'cut the fluff' does the sentence makes sense?

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.
More than 300 rivers drain into Siberia's Lake Baikal more than all the North American Great Lakes combined.

Dear TGC,
I'm happy to respond.

Simply put, you cut the wrong fluff. The structure of this sentence is:
[independent clause][modifier #1[modifier #2]
and "modifier #2" modifies the words "20 percent" in modifier #1. If we eliminate modifier #1, it doesn't make sense, because what modifier #2 is modifying isn't there!

Does all this make sense?

Can someone plz tell me why E i wrng ?
Dear janxavier,
I'm happy to respond. In the original ...
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 phrase "more than all the North American Great Lakes combined" is a comparison to "which holds 20 percent of the world's fresh water." Lake Baikal holds 20%, and this more than the Great Lakes hold. Very clear.

Now, look at (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.
Here, the modifier "More than all the North American Great Lakes combined" appears at the beginning, and modifiers at the beginning of the sentence typically modify the subject, so here it would modify Lake Baikal. This is an illogical comparison. Think about just this comparison.
Siberia's Lake Baikal is more than all the North American Great Lakes combined.
More what? We get some sense of what the sentence is trying to say, but it is not said with precision. In fact, Lake Baikal holds more fresh water than the Great Lakes, but that is not clear from this comparison. The comparison is illogical and incorrect.

Does this make sense?

(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.

I rejected B, after observing ", that" -- comma should not precede that (essential modifier)
Further even if we accept the use of that, comparison is not proper. fresh water is being compared with north American lakes.
Also meaning wise, I think "SLB has 300 rivers" implies that rivers belongs to SLB and they also drain into it.

Dear sri30kanth,
My friend, choice (E) is an illogical comparison, and illogical comparisons are always wrong on the GMAT. Please read my previous post in this thread carefully.

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.

Lets analyze the sentence:

Clause 1 : More than 300 rivers drain into Siberia's Lake Baikal,
Clause 2: which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined

Which correctly modifying Baikal and more is correctly modifying water. This is correct sentence. Subject - Verb agreement is accounted for. Hence there is no problem in A

(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. - Presence of That is awkward. That is modifying water because that is essential modifier and Baikal has more than 300 River is not the intended meaning.

(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. Very awkward sentence. It has no referent. More of and that of is wrong.

(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. : Two clause separated by comma only. Use of while is wrong. Draining of rivers has not to do anything with volume of water.

(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. - Lake can not be more than all the North American Great Lakes combined. Wrong use of Modifier. This is tough choice to reject . This choice confused me a lot.

b]The whole sentence is underlined, indicating modifier or logical predication issue. Keep an eye for intended meaning.
Sentence Structure:
[Clause 1 - Main Clause]
More than 300 rivers drain into Siberia's Lake Baikal,
[Clause 2 - Sub Clause]
which holds 20% of the world's fresh waster, more than all the North American Great Lakes combined. [/b]

(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.
Subject-verb agrees in both clauses; the pronoun 'which' clearly refers to lake Baikal. Modifier "more than..." says fresh water in Lake Baikal is more than all the North Americana 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.
"that is more than" does not have a clear referent -> 20% of the world's fresh water is more than all North American Lakes combined?
"Lake Baikal has more than 300 rivers that..." -> Lake Baikal has rivers? The intended meaning Rivers drain into Lake Baikal.

(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.
"Siberi'a Lake Baikal,bla bla bla, it holds more" missing a Verb for Lake Baikal

(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.
"20 percent of the world's fresh water, which" means 20% of the worlds fresh water is more than Great combined. Not the intended meaning.
Also, "while more than 300 rivers" indicates contrast or simultaneous action. It is true that rivers drain into Lake Baikal and Lake Baikal holds 20% of world's fresh water. Two different information. No need for contrast or simultaneous action word such as 'while'

(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.
More than all the North American Great Lakes combined, Siberia's Lake Baikal -> Lake Baikal is more than all NA Great Lakes combined? Not the intended meaning.
