A. which is the removal of only selected trees, as well as surface fires, burning
B. which removes only selected trees, or surface fires that burn
C. which removes only selected trees, along with surface fires that burn
D. removing only selected trees, or surface fires, burning

A, C and E are wrong because the correct idiom is Either X or Y. Between B and D, B is better. In B "Which" modifies logging better than does "removing" in D. B should be the answer.

I support B.

Here the idiom either..or is correct, and the contrast that burn...but do not is also correct.

It's B.

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which removes only selected trees, or surface fires that burn down individual trees but do not denude the forest.

In D, "burning down" is not parallel with "do not denude the forest".

go with B

either X or Y

'or' is missing in A/C/E

'which' in B quantifies logging.

I think which and that also shuld be paralle.i mean same.either which or that in both the cases..read it one of the OG ques only ( don remember ) so I mean we can have D in the above post as the answer

First of all, I do not agree to the parallel rule you suggesting. Actually it depends on the usage:

X, modifier1 of X, or Y, modifier2 of Y.
X, modifier3 of X, or Y (that ... <-- modifier4 of Y)

Modifier4 is restrictive, rest are non-restrictive.
So, IMO it need not to be parallel.

Also, in the original question with option D:

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, removing only selected trees, or surface fires, burning down individual trees but do not denude the forest

(burning down individual trees but do not denude the forest) is the modifier for surface fires.

Now, tell me how is the above modifier correct?

Hi All,

First of all let's find out that we can eliminate D and E straight away. Why ?

If "V1ing - removing" modifier comes after COMMA, it can play one of two roles.
1. It may modify the whole previous clause. "Rosy started the engine, using the power button"
2. It may show results of previous clause. "Crime has recently decreased in our neighborhood, leading to a rise in properties values."

Here if "removing only selected trees" is modifying previous clause "but such work has not addressed either logging" than it changed the whole meaning of sentence. ""removing only selected trees" also can not show result of previous clause so D and E are wrong.

"which removes only selected trees" is concise than "which is the removal of only selected trees". Why ? because verb "removes" is better than noun "removal". The order of VAN that Verb>Adjective or Adverb>Noun, which eliminate A.

Between B and C, C has error for idiom . "Either X or Y. so answer is B.

I hope my explanation helped. If indeed, please give me kudos.

Hi,
Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.

POE:

A. which is the removal of only selected trees, as well as surface fires, burning: Incorrect.
1. The correct idiom is “either… or…”. This choice uses incorrect idiom “either… as well as…”.
2. Conjunction “but” connects two parallel entities. What follows “but” here “do not denude”, a verb phase. This means the subject “surface fires” should have another verb that cab be contrasted by the use of “but”. But there is no other verb before “but”. “burning” is verb-ing modifier that modifies “surface fires”.
3. Also what follows “either…” should be parallel to what follows “or…”. “is removal of…” is not parallel to “burning down…”.

B. which removes only selected trees, or surface fires that burn: Correct answer.
1. This choice uses the correct idiom “either… or…”.
2. There is a verb before “but” now that results in correct grammatical structure of the sentence. “… that burn… but do not denude…”.
3. “which removes…” is parallel to “that burn…”. Notice that both “which” and “that” are relative pronouns. Entities must be parallel to the extent where they communicate the logical meaning of the sentence by maintaining parallel grammatical structure.

C. which removes only selected trees, along with surface fires that burn: Incorrect. This choice uses incorrect idiom “either… along with…”.

D. removing only selected trees, or surface fires, burning: Incorrect. Same ungrammatical sentence structure issue as in choice A (point#2).

E. removing only selected trees, as well as surface fires that burn: Incorrect. This choice uses the same incorrect idiom as does choice A.

1. Idioms must always be correctly worded.
2. Conjunctions must be used to construct grammatical sentences.
3. Entities in the list must be logically as well as grammatically parallel.

The concepts tested in this sentence have been covered in e-gmat concepts:
1. Level 1 – Sentence Structure Part I & II. (These concepts feature in Level 1 Preview Concepts that are available in Free Trial. Just register and learn.)
2. Level 1 – Idioms – Standard Expressions
3. Level 3 – Parallelism – Identify & Correct.
4. Level 4 – Parallelism – Helpful Tips

Thanks.

i agree with B
I think the biggest problem with D is the "comma+-ing"
it distort the meaning
comma+-ing seems to refer back to the "such work" but not "logging"
I think if we want to use the "-ing" form we should omit the "comma"
that is:
but such work has not addressed either logging removing only selected trees

correct my explanation if i am wrong

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either (X) logging, which is the removal of only selected trees, as well as ( Y )surface fires, (A) burning down individual trees but (B)do not denude the forest.

The sentence is testing sentence structure and idiom. The structure is "either X or Y ( A and B)"

A, C, E are out because they do not follow either X or Y structure.

D is out because it does follow A and B structure.

B is correct. " surface fires ( A )burn down individual trees but ( B )do not denude the forest.

A. which is the removal of only selected trees, as well as surface fires, burning
B. which removes only selected trees, or surface fires that burn
C. which removes only selected trees, along with surface fires that burn
D. removing only selected trees, or surface fires, burning
E. removing only selected trees, as well as surface fires that burn

I have a huge problem with B

logging, which removes....

How can this be correct???

logging doesn't remove... logging is the removal of trees... it's similar to saying: baking, which creates cakes or farming, which grows crops.

I do not see a problem if the name of a process is the subject of an action verb that indicates the result or the outcome of the process.

According to me, the sentences "Baking creates cake." is OK, so is "Logging removes trees."

However it is awkward when the name of the process is the subject of the action verb of the process itself. The actual action taken during the process of "logging" is "cutting" trees. Thus "Logging cuts trees." is awkward.

A. which is the removal of only selected trees, as well as surface fires, burning
B. which removes only selected trees, or surface fires that burn
C. which removes only selected trees, along with surface fires that burn
D. removing only selected trees, or surface fires, burning
E. removing only selected trees, as well as surface fires that burn

This is my analysis:
the correct structure is either X or Y
A. which is the removal of only selected trees, as well as surface fires, burning - out
B. which removes only selected trees, or surface fires that burn - Correct witch and that are parallels and burn and denude are parallel too
C. which removes only selected trees, along with surface fires that burn - out
D. removing only selected trees, or surface fires, burning - burning is parallel correct with removing but not with "do not denude"
E. removing only selected trees, as well as surface fires that burn[/quote] - out

How to differentiate between D and B

Comma + present participle acts as a verb modifier, not a noun modifier. Therefore ", removing...." refers to "has not addressed", not "logging". Also ",burning..." refers to the same verb and not "surface fires".

Steffi defeated Sabatini, winning the Wimbledon.... here ",winning..." does not refer to "Sabatini" - it refers to "defeated".
