Birds of prey have an average wingspan of three feet, but while some have shorter wingspans, some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet or more.

A) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet or more (OR MORE is making this sentence incorrect)

B) the Griffon Vulture, like some others, have a wingspan of at least seven and a half feet (Parallelism error)

C) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet (Correct- Subject= Some others and Verb= Have)

D) the Griffon Vulture has a wingspan of at least seven and a half feet or more, greater than some others (Parallelism error)

E) some others, such as the Griffon Vulture, has a wingspan of at least seven and a half feet (SV agreement error)

zhanbo · Answer

My answer is  (C) . It took me 01:11.

The use of "but" in the un-underlined part is abrupt. If Birds of prey have an average of 3 feet, we certainly expect some with shorter wingspans and others with much longer ones. No real surprise / contrast here to merit a "but". A colon (:) should work better than "but".

(A) " at least  seven and a half feet  or more ": Either "at least" or "or more", but not both.

(B) "like" cannot be used to introduce examples in GMAT. Use "such as" instead.

(D) (1)Either "at least" or "or more", but not both.
(2) To be parallel with "some" in "some have shorter wingspans", we expect to read "others". 
(3) "Greater than some others" is unnecessary. If "some have shorter wingspans" (than three feet), we know only too well that the Griffon Vulture has longer wingspans than some other birds of prey.

(E) "some others" is plural, so "has" should be "have". In making the change, we will get (C).

A) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet  or more  - "or more" makes sentence long

B) the Griffon Vulture,  like  some others, have a wingspan of at least seven and a half feet - sentence presents example, so "like" doesn't indicate example.

C) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet  - Correct

D) the Griffon Vulture has a wingspan of at least seven and a half feet or more, greater than some others - meaning changed

E) some others, such as the Griffon Vulture,  has  a wingspan of at least seven and a half feet - some others  has  - incorrect

parallelism is perfect , have is the right usage therefore let us hang on to it

D) the Griffon Vulture has a wingspan of at least seven and a half feet or more, greater than some others
has isn't the right usage therefore out , greater than some other isn't conveying the right meaning therefore out

E) some others, such as the Griffon Vulture, has a wingspan of at least seven and a half feet
have is the right usage therefore out 
Therefore IMO C

sumitkrocks · Answer

(C)  is correct

A) "or more" is redundant at least seven implies 7 or more.

B) Subject verb disagreement: The Griffon Vulture is singular subject so plural verb "have" is not correct.

C) Correct

D) Same redundancy issue as that in A

E) subject verb disagreement 
Subject, some others, is plural and verb for it is singular.

yasharoraa · Answer

A) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet  or more  
This option brings in redundancy,  at least  alone is sufficient to signify the meaning. -  Incorrect

B)  the Griffon Vulture , like some others,  have  a wingspan of at least seven and a half feet 
This has issue with subject-verb agreement, the Griffon Vulture talks about a particular species of birds, and it agrees with singular verb only. -  Incorrect

C) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet 
This has no redundancy or subject-verb disagreement and is short and precise. We can keep it.

D) the Griffon Vulture has a wingspan of at least seven and a half feet  or more , greater than some others 
This also has the similar redundancy as in option A. Also, there is a slight change in meaning with the phrase  greater than some others  at the end. -  Incorrect

E)  some others , such as the Griffon Vulture,  has  a wingspan of at least seven and a half feet  
This also has subject-verb disagreement.  some others  agrees with a plural verb, hence  have  would be correct here. -  Incorrect

Since, all options are eliminated except C, the  correct answer is C .

Birds of prey have an average wingspan of three feet, 
but 
 while some have shorter wingspans, 
   some others,   
    such as the Griffon Vulture,    
   have wingspans of  at least  seven and a half feet  or more .

Note the redundancy in the usage, between 'at least' and 'more'. Either one of them is sufficient to arrive at the meaning of the sentence. Also, here we see the usage of while to express two different things that co-exists in parallel. Example: In our team, while some prefer ice-cream, others prefer popsicle.

A) some others, such as the Griffon Vulture, have wingspans of  at least  seven and a half feet or  more  
 Redundantly using at least and more together, and hence not concise. Eliminate
 
 B) the Griffon Vulture , like some others,   have  a wingspan of at least seven and a half feet 
 Original sentences is not to compare between birds with shorter wingspan and the Griffon Vulture. Changes the meaning and not parallel to the non-underlined part. The Griffin Vulture is also singular. Eliminate

C) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet 
 Concise, clean and correct. Answer choice is C.

D) the Griffon Vulture has a wingspan of  at least  seven and a half feet or  more , greater than some others 
 Changes the meaning and not parallel to the non-underlined part. The Griffin Vulture is also singular. Eliminate
 
 E) some others, such as the Griffon Vulture,  has  a wingspan of at least seven and a half feet 
 has usage here is singular, while the subject is plural. Eliminate

Correct Option : C

Original sentence:

Elimination Process

3. Have (plural) vs Has (singular)
Wingspans - plural 
Rejects - E - Left with A, D and C

2. 
(At least ...)

Vs (At least X or More + Greater than) --- too wordy and Redundancy
Rejects A, and D -  left with C

3. Have (plural) vs Has (singular)
Wingspans - plural 
Rejects - E
Left with A and C

A) some others,  such as  the Griffon Vulture,  have   wingspans  of at least seven and a half feet  or more

Kanika13395 · Answer

Birds of prey have an average wingspan of three feet, but while some have shorter wingspans, some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet or more.

Initial thought: 
1. Subject verb pairs : Birds of prey...have, some... have, some others... have
2. Pronoun: some refers to birds of prey correctly 
3. Tenses: Everything is simple present so it is correct 
4. List: Such as is correctly used for example

... what is the issue then? is "at least" and "or more" both required in the answer?

A) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet or more -  Redundancy issue

B) the Griffon Vulture, like some others, have a wingspan of at least seven and a half feet-  the sentence now talks about Griffon Vulture in particular but the initial sentence used it like an example.

C) some others, such as the Griffon Vulture, have wingspans of at least seven and a half feet -  Seems to be correct

D) the Griffon Vulture has a wingspan of at least seven and a half feet or more, greater than some others doesn't solve initial issue. It also changes the meaning of the sentence by not using Griffon vulture as an example

E) some others, such as the Griffon Vulture, has a wingspan of at least seven and a half feet  Subject verb agreement error - some others is plural pronoun so it should have a plural verb. 'has' should be replaced with "have"
