While the Eastern Whip-poor-will–a nocturnal bird that feeds mostly in the very early morning–and the Common Nighthawk–a nocturnal bird from the same family that, despite its name, feeds mostly during the morning and evening–appear equal in size to each other when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.

"due to" is correctly used if can be replaced by "caused by"
much larger due to (caused by) its greater wingspan. sounds really wrong and is not correct

Option C uses a semicolon and can be eliminated (no need to use it). D and E remain:

4 appear equal in size to each other when they are sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan
5 appear equal in size when they are seen on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan.

both seem correct, so I would focus on which of the two convey the meaning better.
D uses " appear equal in size to each other", correct, but redundant

This was tough one I picked D for this one... The official explanation said that E conveyed the meaning better since its the people who are viewing the birds rather than the birds viewing each other...

While the Eastern Whip-poor-will–a nocturnal bird that feeds mostly in the very early morning–and the Common Nighthawk–a nocturnal bird from the same family that, despite its name, feeds mostly during the morning and evening–appear equal in size to each other when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.

1 appear equal in size to each other when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.
due to is wrong, due to should be used only when we can replace it by caused by
2 appear equal in size to one another when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.
appear equal in size to one another is wrong here
3 appear equal in size when sitting on a branch or in a nest; in the air, the Common Nighthawk appears much larger because of its greater wingspan.
the part after semicolon lacks a comparision object, hence is incomplete
4 appear equal in size to each other when they are sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan
appear equal in size to each other is wordy when compared to E
5 appear equal in size when they are seen on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan.
Correct

Hope it helps!!

A. appear equal in size to each other when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.
Would have been fine. Except that the use of each other kinda complicates the sentence. You aren't sure whether the author is comparing their sizes or their sizes when sitting on a branch or in a nest.

B. appear equal in size to one another when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.
Whether my analysis for A applies or not, you can never compare two things with one another. You always use each other for such comparisons.

C. appear equal in size when sitting on a branch or in a nest; in the air, the Common Nighthawk appears much larger because of its greater wingspan.
D. appear equal in size to each other when they are sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan.
C is complex in construction. I eliminated D because same size as each other complicates the sentence like in A.

E. appear equal in size when they are seen on a branch or in a nest, in the air, the Common Nighthawk appears much larger because of its greater wingspan.
Perfecto! It's simple, yet conveys the point.

It's a meaning question.

Do the birds look at each other, and think they're the same size? no... that rules out ABC and D.

1 appear equal in size to each other when sitting on a branch or in a nest, in the air, the Common Nighthawk appears much larger due to its greater wingspan.

Well as explained above 'due to' eliminated A and B. C is incorrect because semi-colon is used to separate two sentences which are independent , but have related meaning. The 1st sentence, although long , is in-complete.
While X and Y appear appear equal in size to each other when sitting on a branch or in a nest [this is an incomplete thought or it's a subordinate clause. Semi-colon can't connect subordinate or dependent clauses. Hence this option is out]
D as explained above is out because of redundandancy.

Hence E.

Although E conveys best meaning, E is not 100% correct. A prepositional phrase is placed between two clauses and such construction is technically ambiguous. phrase is eligible to modify any clause.

Subordinate clause, prepositional phrase, main clause.

You don't need a comma for an adverbial phrase that comes after the verb. There is a comma before 'until almost 1900' which shows that the subordinate clause is over. 'Until almost 1900' is a part of the main clause only which starts with an adverbial phrase - no problems here. The issue with this sentence is "did not begin seriously to study". It should be "did not seriously begin to study..." _________________ Karishma Veritas Prep | GMAT Instructor My Blog Get started with Veritas Prep GMAT On Demand for$199

@Karishma,

Problem I shared is from OG-12, Q-3.

Official explanation :
The placement of the phrase until almost 1900 at the beginning of the second clause is confusing. Does it refers back to the first verb or forward to the next verb.

A The tense are fine in this version, but the placement of until almost 1900 is problematic.

Placement of seriously is not even considered in this explanation. OG has emphasized on the placement of modifier.

I know that we can use prepositional phrases at the beginning of a sentence such as :

In the air, bird clause.

but construction like: clause, in the air, clause is creating similar problem as highlighted by OG. I mean what is the grammatical requirement of placing comma after in the air.

(incorrect because of until almost 1900)

Here is the thing - I know that whatever GMAC says has to be taken to be inviolate, but understand that grammar is less about rules and more about logic. No two sentences are the same and it all depends on the context.

Look at two sentences:

Various poets pretended to imitate Native American forms in their own works, until almost 1900.
or
Various poets pretended to imitate Native American forms in their own works until almost 1900.

Do you need the comma? Do you use the comma? No.

Now look at two more sentences:

Until almost 1900, scholars and critics did not begin ...
or
Until almost 1900 scholars and critics did not begin ...

You almost always use a comma when an adverbial phrase starts the sentence.

Now the point is that "until almost 1900" could logically go with both clauses and even though the commas clarify the sentence, it may still be considered unclear because there is a better option available. Also, "begin to study" should not be split up since it becomes awkward. So the adverb "seriously" should come before "begin".
Note that official explanations will not point out all errors with a sentence so don't put too much faith in them.

As for the original question, notice that
The Eastern and the Common appear equal in size when they are seen on a branch or in a nest, in the air.

This makes no sense and it is obvious that 'in the air' belongs to the main clause. The commas also clarify this situation. Hence there is nothing wrong with this sentence.

Please assist, Thanks and Regards, Prakhar Here is the thing about original meaning - it doesn't exist. Note that option (A) is in no way superior to other 4 options. The probability of option (A) being correct is 20% only. The distinction is not "original meaning" vs "altered meaning"; it is "logical" vs "illogical" meaning. In option (A) and (D), "...equal in size to each other..." is somewhat illogical. For an onlooker, two things could be equal in size. They are not equal in size to each other. On the other hand, you can say that when they stood side by side, they found that they were equal in height to each other... etc. So you need to find the logically correct sentence. Option (E) is more appropriate because they appear equal in size to the onlookers. _________________ Karishma Veritas Prep | GMAT Instructor My Blog Get started with Veritas Prep GMAT On Demand for$199
