Hello arghya05,

Thanks for the quick reply . But can you please give me the reasons for selecting the answers .

BTW the answer to the second question is not correct .

for Q 2

check grammar before check meaning logic or die

"having done" never attach a noun. this is very basic grammar. see the grammar book for this. having done shows a previous action and so can not be used after a noun.

in b , so smooth and so perfectly shaped is not paralel

in d, smooth manner is not logic

in c, smooth and perfect can not modify shaped. I am not clear of this. Maybe "shape" is like "look" and can go with adjective
PLS, HELP WITH THIS

a is left. IMO

VERY HARD

Q2, C is correct. meaning in C is more logic than in A.

it is shaped smoothly. it is created without problem. this is not logic. A is wrong

Well can you please explain why you are selecting the answers in Q1 and Q2 . Q2 I got the explanation can you explain Q1.

OA please.

[spoiler]1: E - percent increase
2: B - so...so is parallel and logical[/spoiler]

Thanks for your reply .

The answers are indeed :

Q1 E

Q2 B

In Ques 2, Can any one explain why is it option B?

According to me it should be Option C.


As in option C,

First, "that" is correctly refering to "wings".

Second, as parallelism is concerned then "smooth and perfect" are parallel.

Third, "so" can be assumed after "and" also.

Q1: was easy

Q2: is hard...

I thought it was C.

But B:so smooth and so perfectly shaped

if so ...so has to be parallel.. shouldn't the construction also be parallel...

so smooth so perfect.... but so smooth and so perfectly is incorrect in my opinion.

so for that reason.. i would say B is wrong?????

C is correct.... that are shaped so smooth and (so) perfect ..that

Any other explanation plz.

According to me, the C is logically incorrect.
That's because " Wings are shaped smooth" is not correct English.
The wings have to be smooth, and not the shaping process/ method.

The option B with "smooth" and "perfectly shaped" describe the Wings.

nirmalp your explanation for option B is perfect .
