 Post subject: More than 300 rivers drain into  Posted: Sun Oct 05, 2008 11:08 am
 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. OA is A. Why E is wrong? Does it mean Siberia's Lake Baikal holds... more than all the North American Great Lakes combined (do)? In A, More than 300 rivers drain into Siberia's Lake Baikal, .. more than all the North American Great Lakes combined (do). But Great Lakes can not drain! Thanks.

 You're reading the last part of the sentence in A incorrectly. That final component, starting with "more...", refers to "water," not all the way back to "Lake Baikal." As a result, A is perfectly okay. E is wrong for a couple of reasons. For one thing, we're sandwiching the subject of the sentence between two modifiers. Furthermore, by misplacing the "more than..." modifier, we have obscured the intended meaning of that phrase.

 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. After removing the non-restrictive clause in A, More than 300 rivers drain into S's Lake Bikul,<>, more than all the North American Great lakes combined. I have a question, Does it mean that "more than all the North American Great lakes combined." modify the whole sentence of "More than 300 rivers drain into S's Lake Bikul" ?

"more than all the North American Great lakes combined." an appositive noun modifier to modify the entire sentence"More than 300 rivers drain into S's Lake Bikul" ?

 My understanding has been that the sentence should make sense even when "which holds 20 percent of the world's fresh water" is removed but in this case when that part is removed "More than 300 rivers drain into Siberia's Lake Baikal, more than all the North American Great Lakes combined" does not make much sense. Please explain. Thanks Karthik

Please explain.ThanksKarthik 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!

Can anybody please explain?choice (b) starts out withWith 20 percent of the world's fresh water, that is more than ...this could potentially be read in two ways, both of which are incorrect:(INCORRECT READING 1) "that" is a pronoun (in the same way you'd point at a menu and say "i want that")to use that in this way - by itself as a pronoun, as a "pointing word" - is always incorrect in formal written english."that" CAN be used as a pronoun, but only if it's in a parallel construction (such as the capacity of tank A vs. that of tank B).(INCORRECT READING 2)it's a relative pronoun (in the same way you'd write "here's the book that i read").two things wrong here.one, you don't put a comma before this kind of "that".two, even if this were written correctly (i.e., without the comma), which it isn't, you'd still be saying 20% of the water that is more than the great lakes. i.e., there is SOME SPECIFIC water that is "more than the great lakes", and we're talking about 20% of that water. that doesn't make sense.so, wrong either way. _________________Pueden hacerle preguntas a Ron en castellanoPotete fare domande a Ron in italianoOn peut poser des questions à Ron en françaisVoit esittää kysymyksiä Ron:lle myös suomeksiUn bon vêtement, c'est un passeport pour le bonheur.– Yves Saint-Laurent

(but i can still see why you're asking about it, though) _________________Pueden hacerle preguntas a Ron en castellanoPotete fare domande a Ron in italianoOn peut poser des questions à Ron en françaisVoit esittää kysymyksiä Ron:lle myös suomeksiUn bon vêtement, c'est un passeport pour le bonheur.– Yves Saint-Laurent

 Hey guys,If I understand it correctly, the phrase "more than all the North American Great Lakes combined" is an adverbial modifier, so it is supposed to modify an action, which is "holds". Because in E), "more than all the North American Great Lakes" is far away from what it is supposed to modify. For example, we have another adverbial modifier, "with more than 300 rivers draining into it", in between "more than all..." and "holds 20 percent...", it is not clear what "more than all the North American..." modifies in this case. Therefore I will say that A) is better than E) because the adverbial phrases clearly modifies the action "holds".

 If I understand it correctly, the phrase "more than all the North American Great Lakes combined" is an adverbial modifier,That's not unreasonable--after all, "more" is sometimes an adverb--but it's wrong in this case. "More" can also be an adjective, or even a noun. "A noun?," you ask, "Surely you're joking." Well, consider the sentence "Oliver asked for more." The object of that sentence, the THING for which Oliver asked, is "more." OK, maybe you want to say that "more" here is an adjective modifying an unstated noun, "Oliver asked for more (gruel)." I'd call that a distinction without a difference.How does that apply to the present sentence? Consider this modified form of A,More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more (water) than all the North American Great Lakes combined. The entire phrase "more (water) than all the North American Great Lakes combined" is an appositive, a noun phrase used to modify another noun phrase. In this case it modifies the noun phrase "20 percent of the world's fresh water." This is so whether you treat "more" as an noun, or whether you treat "more" as modifying the unstated "water."
