There is always a reason why a choice is wordy. What's that in this sentence?
"Any other" is better than just "any". The "other" is very vital here.
What is "it" referring to?
What is the effect of "comma + verb-Ing" form?

\(NAIL\) \(THE\) \(SENTENCE\) \(CORRECTION\) \(SECTION\)

After spending plenty of time in the Sentence Correction section, one thing I can assure each and every member is that the best technique to nail the SC section is to try and find out as many errors in an answer choice as possible. In general, if one observes he may find atleast 3 errors in all the incorrect answer choices. So the motive behind this topic is to destroy each Official question in SC.
By discussion we will equip ourselves with every weapon in order to conquer SC section.

Advantages of SC:
1) With sufficient skills, we CAN solve any SC question under a minute.
2) Finding all the errors while practicing can help us solve each SC question under a minute in real test.
3) No brain is needed. Just the application of rules.
4) Time saved in SC is the bonus for the rest of the verbal section.

NOTE: UNSOURCED QUESTIONS WILL IMMEDIATELY BE REMOVED AND 1000 SERIES IS PROHIBITED.

P.S. I am fed of the pathetic explanations of OG.

Ans:- C

C) that, unlike any other known insect, spends ---- correct comparison, since "that"(species of midge) is acting as a subject here and is being compared correctly.

On a glacier in the high Himalayas, a Japanese zoologist has found a species of midge that is unlike any other known insect in its spending its entire life cycle in the snow and ice of glacier.

a)that is unlike any other known insect in its spending
b)that is unlike any insect known as it spends
c)that, unlike any other known insect, spends
d)unlike any insect known as it spends
e)unlike any other insect that is known, spending

Meaning:
Sentence says that Japanese zoologist has found a species of midge, and this species is unlike any other species because it spends its entire life in snow.

a)The problem with original choice is that its spending its entire life cycle phrase can act as Noun Modifier modifying phrase "any other know insect" or can act as adverbial modifier modifying clause " How species of midge is different from other insects?". hence ambiguous.

b) it spends - it can serve as a referrent of Zoologist, since it is subjective pronoun can act in place of subjective "noun"

c) correct - ambiguity is removed.

d) has same error as that of b

e) changes meaning. presenting the result of an effect. Moreover, redundant construction

IMO C
Choice C clearly uses that to refer to midge followed by ,.......insect used as modifier followed by , spends correctly refers to that singular midge

A, B, D and E distorts meaning

On a glacier in the high Himalayas, a Japanese zoologist has found a species of midge that is unlike any other known insect in its spending its entire life cycle in the snow and ice of glacier.

a) that is unlike any other known insect in its spending............its spending its lifecycle seems awkward with redundancy.
b) that is unlike any insect known as it spends................as it spends defines a reason for not being like others but it is not mentioned so.
c) that, unlike any other known insect, spends..........seems best and short.
d) unlike any insect known as it spends..............unlike seems to refer midge but needs a realtive pronoun to refer it.
e) unlike any other insect that is known, spending.................unlike spoils the dish again. Also spending suggests that Zoologist found midge while spending and again its life indicates that you are not getting the intended meaning.
Also that is known is redundant just like B instead of known insect.

Also any other vs any is one more criteria mentioned in below link.

Why is B and D wrong?

I can't seem to understand the explanations...

On a glacier in the high Himalayas, a Japanese zoologist has found a species of midge that is unlike any other known insect in its spending its entire life cycle in the snow and ice of glacier.

a) that is unlike any other known insect in its spending
b) that is unlike any insect known as it spends
c) that, unlike any other known insect, spends
d) unlike any insect known as it spends
e) unlike any other insect that is known, spending

Ignore "On a ...Himalayas" (prepositional phrase).

I think this sentence is trying to convey two things: The zoologist found a species of midge "that is unlike any other known insect" AND "that spends its entire life cycle in the snow and ice of a glacier".

C) is best b/c you can eliminate "unlike any other known insect", and it reads perfectly: that spends.

* "it" is an ambiguous pronoun -- could refer to "insect" or "midge". Elim B, D
* spending = incorrect. Elim A, E.

kudos please if you find this helpful

GMATNinja, GMATNinjaTwo, DmitryFarber, Does comma in answer choice C been used correctly?

C is best option. A is awkward. As it spends it refers to insect? Ambiguous d also same reason.incomplete sentence.

Good question, ziyuen. And yes, the commas are completely fine. The phrase inside the commas is just setting up a comparison with the midge, and the commas help separate it from the rest of the sentence.

Consider the following:

Unlike any other known insect, midges live in glaciers.
Midges, unlike any other known insect, live in glaciers.

No problem with either of these, right? The comparison is correct, and in that second sentence, you clearly need the commas for separation. (C) is similar, expect that now the "unlike..." phrase is part of a modifier beginning with "that":



So the commas correctly separate the description from the rest of the clause. It would be muddier without the commas.

But for whatever it's worth: I can't really think of any GMAT SC questions that really test you on comma usage. Semicolons, perhaps -- but comma usage is never a deciding factor.

I hope this helps!

Hi,
Please explain the grammatical mistake in A . I know it is worded and best answer is C , but I am not able to find any grammatical mistake.

Answer Explanation Close
Grammatical construction; Logical predication; Rhetorical construction

The sentence reports a zoologist’s discovery of a species of midge that is unique among all the insect species on earth. The sentence needs to clarify that the species discovered is being compared to other insects.

A. The phrase in its spending its is awkward and confusing because of the unnecessary repetition of its.
B. Without other to modify insect, the sentence excludes species of midge from the category insect where it logically belongs.
C. Correct. The qualified category other known insects is logically distinct from the noun midge, so the comparison makes sense.
D. The category insect must be qualified by the adjective other, as explained in C.
E. The phrase that is introduces unnecessary words to this version of the sentence. Because of its placement, the adjective phrase spending its entire life . . . seems at first to be describing the Japanese zoologist, not the midge.

The correct answer is C.

C compares the right things while also keeping the grammar intact, clear choice.

E. The phrase that is introduces unnecessary words to this version of the sentence. Because of its placement, the adjective phrase spending its entire life . . . seems at first to be describing the Japanese zoologist, not the midge.

The correct answer is C.

(A) that is unlike any other known insect in its spending

1) POSSESSIVE + V_ING + DIRECT OBJECT is the structure that is used here: "its spending its entire life cycle".
And this structure is wrong on gmat.

2) there is a noticeable difference between two structures used in A and C:

1) Midge is unlike any other insects in its life cycle.
2) Midge is unlike any other insects in its living in the snow.
3) Midge, unlike any other insects, spends its entire life cycle in the snow and ice.
4) Midge is unlike any other insects in that it spends its entire life cycle in the snow and ice.

the first two mean that Midge and other insects do the same thing, but in a different way. For example, Midge and other insects live in the snow, But HOW they live in the snow is different.

the last two mean that Midge spends its entire life cycle in the snow and ice, while other insects don't at all.

the latter conveys the intended meaning.
Here is the better explanation from RonPurewal: https://www.manhattanprep.com/gmat/foru ... tml#p86665

(B) that is unlike any insect known as it spends

1) here "because" and "as" have the same meaning: if you replace "as" with "because", it becomes more clear that we have not the intended meaning ,if not illogical meaning: a Japanese zoologist has found a species of midge....because it spends its entire life in the snow. The midge spends its entire life in the snow and ice, SO a zoologist found it. Not intended meaning

2) this choice says midge is unlike any known insect, but does not clearly describe HOW it is different from others

3) this choice omits the word "other" between "any" and "insect", so can two problems:
1) this choice excludes midge from a category of "KNOWN INSECTS"
OR
2) this choice seems to compare midge with a group of known insects that includes the midge itself


(C) that, unlike any other known insect, spends

1) this answer choice clearly gives the intended meaning: the midge, unlike any other known insects, spends its entire life in the snow and ice of glacier. In other words, the midge spends its entire life in the snow and ice of glacier, while other known insects do not.

(D) unlike any insect known as it spends

1) the same problems as in B


(E) unlike any other insect that is known, spending

1) "comma + V_ing" usually modifies the nearest action and its agent, so "comma + spending" no longer modifies "the midge". Instead, it seems to modify "any other insect" and "is known", but I cannot get any logical interpretation from this.

2) this choice says midge is unlike any known insect, but does not clearly describe HOW it is different from others
