Ans: C
Ospreys, as most birds of prey, hunt for their prey while in flight, although it is uncertain whether the height that they hover at differs according to species.

(A) Ospreys, as most birds of prey, hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species; as has to be followed by a clause to make a valid comparison.

(B) Ospreys hunt for their prey while in flight, as most birds of prey do, although it is uncertain if the height that they hover at differs according to species; use of if is incorrect. when a subordinate clause comes after the main clause no comma is used like in option A

(C) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species; comparison is correct. use of whether is correct

(D) As most birds of prey, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species; similar to option A: comparison error.

(E) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species or not; use of whether..or not.. is redundant

notes: comparison between noun/n-phrases, use "like", and comp between clauses, use "as" - a clause needs a verb, so we need "as....do"; "whether" is used when there are few alternative possibilities, and "if" is used when there are more or used as a conditional - in this case we need "whether"; also it is unidiomatic to say "whether...or not".

issue analysis in the original statement:
Ospreys, as most birds of prey -- as is used faulty ( here like could have been used)

The answer that corrects this is BCE
B uses if instead of weather and E uses weather or not which is wrong

Correct answer is C

OFFICIAL EXPLANATION



Ospreys, as most birds of prey, hunt for their prey while in flight, although it is uncertain whether the height that they hover at differs according to species.


(A) Ospreys, as most birds of prey, hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species

This answer choice is grammatically incorrect. A comparative section beginning with as should always include a conjugated verb. The comparative section in this answer choice (as most birds of prey), however, does not include a verb.

What helps us identify this question as a Comparative question as well as the mistake is the following Stop Sign: Like, unlike, than, as



(B) Ospreys hunt for their prey while in flight, as most birds of prey do, although it is uncertain if the height that they hover at differs according to species

Although this answer choice corrects the original Comparative error by adding a verb (do) to the As section, in the GMAT, If is used in Conditionals only. If you see if in a sentence and there's no condition, you should replace if with whether.

Think of whether as a choice between two possibilities dealing with the same subject or as a yes/no question.

    Example: I do not know whether this will work. (yes or no)

    He was not sure whether he wanted banana or chocolate cake. (a choice between 2 possibilities)



(C) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species

This answer choice corrects the original Comparative error by adding a verb (do) to the As section.


(D) As most birds of prey, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species

This answer choice is grammatically incorrect and repeats the original Comparative error. A comparative section beginning with as should always include a conjugated verb. The comparative section in this answer choice (As most birds of prey), however, does not include a verb.

What helps us identify this question as a Comparative question as well as the mistake is the following Stop Sign: Like, unlike, than, as



(E) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species or not

Although this answer choice corrects the original Comparative error by adding a verb (do) to the As section, in the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant.

Ospreys, as most birds of prey, hunt for their prey while in flight, although it is uncertain whether the height that they hover at differs according to species.

(A) Ospreys, as most birds of prey, hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species
- (A) conveys the meaning that Ospreys take on the role of 'most birds of prey' to hunt. This does not make any sense.

(B) Ospreys hunt for their prey while in flight, as most birds of prey do, although it is uncertain if the height that they hover at differs according to species
- to highlight uncertainties, we need to use 'whether', not 'if'.

(C) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species- has no error here. Hence, (C) is the right answer choice.

(D) As most birds of prey, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species - Has the same meaning error as described in (A): Osprey takes on the role of 'most birds of prey' when they hunt.


(E) As most birds of prey do, Ospreys hunt for their prey while in flight although it is uncertain whether the height that they hover at differs according to species or not
- uses the incorrect idiom structure ''whether or not''

If you find this explanation helpful, please do give it a kudos. :thumbsup: :)
