I am not very confident on this one, but if it were in the test I would choose C.

D and E has second 'that' which is incorrect. 'increasing' in C sounds right because it's a continuing process.

I choose B as well.

unfortunately I'm using the "it's sounds the best to me" approach. Nothing scientific.

A - CO2 is not as a result of burning but instead it's resulting from the process of burning
B - CO2 increase has not stopped. Also ..increased CO2 ... would cool... does not sound right
C - Correct
D - Tense problem
E - Awkward

I chose A initially...but I think 'as a result of' is redundant in this case.

B is the best of all choices...but isn't increased CO2 resulting...awkward...how could a past event be affected by a present progressive event...any thoughts??

in the context of this sentence, 'increased' is used as an adverb to modify CO2 not as a verb.

D) and E) have modifier problem

out of two below, 1st one sounds right to me.
- increased co2 would cool the globe.
- increading co2 would cool the globe.

B) is the best choice.

"increased" is not an adverb. It's an Adjective (A past participle used as an adjective).

Well answer should be B.

"Resulting from" is a correct idiom.

This is correct. Though I am confused between A and B:

Quote:
(A) increased atmospheric carbon dioxide as a result of burning
(B) increased atmospheric carbon dioxide resulting from the combustion of


"as a result of" is a correct idiom too. Why is A incorrect?

See, In A, "increased" is used as an adjective.

If we had used "increased" as verb then A would have been a right choice, in which case sentence would like like:

Contrary to earlier conjectures, it may be that atmospheric carbon dioxide increased as a result of burning fossil fuels would cool the globe by reducing the amount of solar energy absorbed by snow.

In the above sentence "increased" is used as a Verb .
Why CO2 increased? It increased as a result of burning fossil fuels.

Does it make sense?

Re: SC ....Contrary to earlier conjectures..... [#permalink] New post 25 Feb 2008, 09:29
Also, someone correct me if I am wrong........ the meaning is vague in the other choices in A does burning act as a verb? burning fossil fuels as a verb meaning the act of burning the fuels or a gerund, burning fossil fuels in my mind means fossil fuels which are burning


Therefore B is the best

Contrary to earlier conjectures, it may be that increased atmospheric carbon dioxide as a result of burning fossil fuels would cool the globe by reducing the amount of solar energy absorbed by snow.

(A) increased atmospheric carbon dioxide as a result of burning
what does "as a result" refer to?
(B) increased atmospheric carbon dioxide resulting from the combustion of
correct. resulting refers to increased carbon dioxide.
(C) increasing carbon dioxide in the atmosphere resulting from the combustion of
it seems that the practice of increasing would cool..., changing the meaning. moreover, does resulting refer to atmosphere? unclear
(D) carbon dioxide in the atmosphere that increase from burning
that is unclear
(E) atmospheric carbon dioxide that increased from burning
wrong tense

Thanks! This is a perfect angle to cut in.

OA is B. The context means that "Maybe atmospheric carbon dioxide has reached a certain degree, it would thus cool the globe".

(A) increased atmospheric carbon dioxide as a result of burning
Grammatically correct. I would choose A if there is no B.
Here "increased atmospheric carbon dioxide" is correct, because it means that the CO2 has already reached a certain degree.

(B) increased atmospheric carbon dioxide resulting from the combustion of
Correct. Will compare with A later.

(C) increasing carbon dioxide in the atmosphere resulting from the combustion of
Wrong.
(1) Changed the meaning of the sentence. "increasing" is incorrectly used. It means that CO2 level is still increasing.
(2) Redundant. "carbon dioxide in the atmosphere" equals "atmospheric carbon dioxide" but is much longer.

(D) carbon dioxide in the atmosphere that increase from burning
(1) Redundant. "carbon dioxide in the atmosphere" equals "atmospheric carbon dioxide" but is much longer.
(2) The function of "increase" changed.
Originally, "increase" is used to describe the CO2 level.
However, here "increase" is used to describe how CO2 is formed.
(3) The tense of "increase" is wrong. The increase must have happened before we speak.

(E) atmospheric carbon dioxide that increased from burning
The function of "increase" changed.
Originally, "increase" is used to describe the CO2 level.
However, here "increase" is used to describe how CO2 is formed.

Now let's compare A and B. From the first sight they are the same:
(A) increased atmospheric carbon dioxide (as a result of burning)
(B) increased atmospheric carbon dioxide (resulting from the combustion of)

However, if we look carefully into the brackets, we find that in A "as a result of burning" is a prepositional phrase that works as an attribute; while in B, "resulting from the combustion of" is a present participle phrase that also work as an attribute.

The only difference between A and B is that:
(1) In A, "result" is a noun that has some connectiontion with CO2, either direct or indirect, we can't tell.
(2) In B, "resulting" is a verb, an action that is received directly by CO2.

Therefore, B is better.

Expert's post
Fossil fuels (coal, crude oil and natural gas) are those that have been fossilized from millions of years ago. The process of using them is called combustion, which is to ignite them in a closed chamber such as a furnace, an engine etc; Combustion’s main purpose is to harness heat.

On the contrary burning refers to using sources such as wood that are not fossilized but used immediately. Burning is mostly done in open fires. The purpose here would be mostly for lighting and sometimes to generate heat like in cooking.

Base on the above description choices A, D and E. that call usage of fossil fuel as burning are out. Between B and C: Increased atmospheric CO2 means, high level of CO2. This is the correct meaning as in B;

However, it may be that increasing Co2 in the atmosphere may mean two things. 1. Increasing may be an on - going effect or it may mean that increasing CO2 in the atmosphere by some agent; both the prospects are not the intended meaning. So C is out
