AkshdeepS · Answer

A from other birds.
B from other birds.
C from that of other birds.
D than those of birds.
E than is other birds

B is not correct  devikeerthansr

A and B are not correct as both are comparing "wings" with "other birds".

D is clearly out as it is using just "birds' in general.

D and E are also using "than" at place of "from". IMO this is wrong as we need "different from" to show comparison of two similar things.

I don't see any problem with C other than the use of "that" to describe "wings", which is of a living being.

I have corrected it to : from other birds'

seed · Answer

A from other  birds .  - Incorrect. Comparison between wings and birds.

B from other birds'.  - Correct. The sentence actually becomes "Since ostriches cannot fly, their wings are very different from other birds'    (wings).

C from  that of  other birds.  - Incorrect. "that" doesn't have a clear referent, if it refers to wings then it is incorrect because wings is plural.

D  than those of  birds.  - Incorrect. "Different from" seems to be the correct form here. "those" seems to refer to wings which looks correct to me. Even then the sentence will be    than wings of birds   which is illogical.

E than is other  birds   - Incorrect. Comparison between wings and birds.

Answer: (B).

IMO both options B and C are grammatically correct, because of conciseness B is the winner.

Hello

Quick clarification. May be  dave13  and  emockus  can help.

In option B we don't have the word "wings" mentioned at the end. So we don't need to include the entity whose possession we are too.

In option C: Can that not refer to the wings of birds? if it can then why is it wrong.

seed · Answer

In option C: Can that not refer to the wings of birds? if it can then why is it wrong. - If I can answer

"that" always refer to singular so here "that" cannot refer to "wings" hence, C is out.

anupam87 · Answer

A from other birds. –  Comparing wings to birds.  
B from other birds'. –  Comparing wings to wings. - Correct 
C from that of other birds. –  Wings is plural and here “that” refers to plural “wings”.  
D than those of birds. –  wrong comparison.  
E than is other birds. –  Incorrect and doesn’t make any sense.

Adi93 · Answer

different from is correct in the current context.
D and E are Out.In A the comparison is absurd and in C that is wrong, we need plural those to refer wings.Hence, B is the answer.
