Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation,............................. , they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).

30 seconds approach, even less .

I do not even rely on idioms or else........only in case of blurry situations.

Good job :)

@ Carcass.
Your approach is definitely quick and correct. I went to the same thinking as yours but after taking 2 minutes. Bad!. At first I thought the "acting....and keeping" phrase must be the modifier and quickly went to A and B. However, I stuck a little bit because I just read the underlined part and thought the phrase "while....." is contrast with "acting.....and keeping...". Fortunately, I saw "although" at the beginning and finally picked A.

@pqhai

your analyses is right and at the same time the fact you said: thanks I noticed the contrast word although is the flawed part ....

I mean: even if I do not notice this word at the beginning of the sentence (maybe distracted or else) reading the first non underlined part, it clearly states that something positive the particles do. Consequently, what follows must be a clear counterpart.

The first part goes up (in a positive sense) so the second part must go down clearly (in a negative way). B C D and E, the rightmost underlined portion of the sentence re-shifts the entire meaning in another direction that is not so clear (positive or negative). We need a clear cut, instead.

Of course , this process takes a while to put in place in your mind but believe me : it is worth; in conjuction with your grammar knowledge, the process is boosted immensely.

:wink:

@Carcass.
I agree with you. The approach is worth to practice. "Meaning" is always my weakness. Tips and tricks do not help out in the long term. :) thank you my friend.

Best!

options B and D are out due to either ..... or .... issue.
Among A ,C and E , option A has comma + ing modifier modifying the entire clause. Hence correct .
In option C, while also accelerating is wrong .
In option E, but is redundant

hello friends..

in option A.."although" thing is okay..(although X,Y)
but in option A, "acting as global thermostat..."..doesn`t it seem to modify the "solar radiation"..rather it should modify the ice particles.

anybody plz correct me ..

(A) acting as global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate

CORRECT: This answer choice conveys the intended meaning in a clear and idiomatically correct fashion;
Adverbial modifier -- acting as a global thermostat -- correctly modifies the clause about the ice particles' reflection and absorption of solar radiation, describing the results of those phenomena
The main clause ‘they also accelerate’ starts in the correct place, and, as expected from subordinating conjunction ‘although’, stands in conceptual opposition to the subordinate clause that begins the sentence; The subordinating conjunction ‘although’ is used to introduce a contrast BETWEEN the clause introduced by ‘although’ (subordinate clause) AND the clause following the comma (main clause) - ‘Although [subordinate clause], [main clause]’;



(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating

Meaning: the placement of the preposition ‘from’ in the construction ‘keeping Earth EITHER from burning up OR freezing over’ doesn’t make sense in the given context, as it implies that preposition ‘from’ applies only to the first part of the construction; In other words, ‘Ice particles act as global thermostat and thus EITHER keep Earth from burning up OR keep Earth freezing over’; obviously, the preposition ‘from’ has to be placed before the ‘EITHER..OR’ construction, because ‘keeping Earth freezing over’ doesn’t logically qualify as a ‘benefit’: ‘… thus keeping Earth from EITHER burning up OR freezing over…’
Construction: subordinating conjunction ‘Although’ is used to introduce a contrast BETWEEN the clause introduced by ‘although’ (subordinate clause) AND the clause following the comma (main clause) - ‘Although [subordinate clause], [main clause]’. This answer choice is a sentence fragment, as it lacks the main clause and consists of one subordinate clause followed by modifiers - ‘Although [subordinate clause], [modifier], [modifier], [main clause –missing]’; furthermore, since the main clause is missing, the implication is that the modifier ‘while also accelerating the destruction of the ozone layer by reacting with chlorofluorocarbons’ is further describing the benefits of ice particles, whereas, clearly, there is nothing beneficial in the destruction of ozone layer;


(C) act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating

Meaning/Construction: This answer choice makes no grammatical sense; it seems to present a list of benefits, but with complete disregard to parallelism and punctuation: ‘reflect and absorb..., act as X, and thus..., while also accelerating ....’; furthermore, this answer choice is a sentence fragment, as it lacks the main clause and consists of one subordinate clause followed by a long modifier - ‘Although [subordinate clause], [modifier], [main clause –missing]’; furthermore, since the main clause is missing, the implication is that the modifier ‘while also accelerating the destruction of the ozone layer by reacting with chlorofluorocarbons’ is further describing the benefits of ice particles, whereas, clearly, there is nothing beneficial in the destruction of ozone layer;


(D) they act as a global thermostat that thus keeps the Earth either from burning up or freezing over even though it also accelerates

Meaning: the subordinating conjunction ‘Although’ is used to introduce a contrast BETWEEN the clause introduced by ‘although’ (subordinate clause) AND the clause following the comma (main clause) - ‘Although [subordinate clause], [main clause]’; Clearly, there is no apparent contrast between the subordinate clause (Although ice particles benefit Earth in that they reflect and absorb solar radiation) and the main clause (they act as a global thermostat)’; on the contrary, the ‘global thermostat’ idea flows smoothly from the ice particles' reflection and absorption of solar radiation.
Unidiomatic: construction ‘thermostat that THUS keeps’ is unidiomatic, the ‘thus’ is completely out of place and unnecessary;
Meaning: the placement of the preposition ‘from’ in the construction ‘keeps the Earth EITHER from burning up OR freezing over’ doesn’t make sense in the given context, as it implies that preposition ‘from’ applies only to the first part of the construction; In other words, ‘Ice particles act as global thermostat and thus EITHER keep Earth from burning up OR keep Earth freezing over’; obviously, the preposition ‘from’ has to be placed before the ‘EITHER..OR’ construction, because ‘keeping Earth freezing over’ doesn’t logically qualify as a ‘benefit’;
Awkward: aside from using a contrasting conjunction ‘although’ without apparent contrast, this answer choice adds another contrasting conjunction ‘even though’, thereby creating an even more awkward sentence;


(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate

Meaning: the subordinating conjunction ‘Although’ is used to introduce a contrast BETWEEN the clause introduced by ‘although’ (subordinate clause) AND the clause following the comma (main clause) - ‘Although [subordinate clause], [main clause]’; Clearly, there is no apparent contrast between the subordinate clause (Although ice particles benefit Earth in that they reflect and absorb solar radiation) and the main clause (they act as a global thermostat)’; on the contrary, the ‘global thermostat’ idea flows smoothly from the ice particles' reflection and absorption of solar radiation.
Meaning: construction ‘they (ice particles) act as thermostat TO THUS keep Earth…’ nonsensically implies that ‘ice particles intentionally act as thermostat to protect the earth from extreme temperatures’, obviously ‘ice particles are inanimate objects that don’t have free will, not to mention intentions’
Awkward: aside from using a contrasting conjunction ‘although’ without apparent contrast, this answer choice adds another contrasting conjunction ‘but’, thereby creating an even more awkward sentence;

Try to solve ONLY from the meaning standing point. Thanks


in E, "to do" is used to show purpose of main verb, "thus" is used to show effect of main verb. So, "to do" can not go with "thus". E is wrong

Kind of a simple, quick way to determine the answer choice in modifier questions such as these (it does not always apply) is to omit the modifier in the commas. When you take the portion of the sentence in the commas out you realize that the only logical answer choice is "A":

"Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation...they also accelerate the destruction...".

All of the other answer choices are illogical.

Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).

(A) acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate :
Correct : modifier “acting” correctly modifies the verb benefit
Construction of “Although ….., they also ….” Is correct

(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
Incorrect : parallelism error “either from burning up or (from) freezing” – from is required before “freezing” to correct this error
Construction of “Although …., while …” is awkward and incorrect

(C) act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating
Incorrect : Construction of “Although …., while …” is awkward and incorrect
Verb “act” is now associated with ice particles and is highlighting another action of the ice particles rather than providing information about how they benefit earth.

(D) they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
Incorrect : Construction “although ….even though” redundant…
Pronoun error : “it also accelerates” – is singular ..we are talking about ice particles (plural)

(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
Incorrect : “they act …to thus keep earth ….” Change in meaning
They act that way and thus it helps earth…they do NOT in particular act that way IN ORDER to help earth…

[Reveal] Spoiler:
Can somebody please explain the sentence structure and why certain answer choices are wrong? Thanks.


This sentence tests several things: Sentence construction, idiom and verb agreements
- The sentence starts with "although", which makes the sentence a subordinate; therefore B and C are OUT since there's not an independent clause; B also contains an idiomatic mistake in "either X or Y".
- D is out because "it" wrongly refers to "participles"
- E is out because "but" is both redundant (contrast already shown at the beginning with although - subordinating conjuction) and wrongly open an independent clause, leaving the sentence without an independent clause.

A is CORRECT

"Acting" is the participial phrase that modifies the prior clause. Nothing wrong with the original way in which the sentence is written.

B) parallelism problem

C) run on sentence.

D) that thus?
