OA to follow

IMO B

IMO B.

The verb following among is determined by what follows among. In this case singular atomic bomb so 'was' is the right usage.

Among all the inventions were/are X and Y ...

Among all the inventions was/is X ...

Among all the inventions was/is X ...

Can you explain why not C (Simple present). OA - B

The whole sentence is made up of simple past. Why do we need to use simple present/change the tense ? Or am I missing something here ?

A number ... shaped ... invention that was ...

IMO B.
The invention is singular so "was" will follow.
IMO "is " is not correct beacause in the preceding ,it is written that " the invention that was the most important"


Whats the OA??

IMO B

was the atomic bomb that demonstrated - the demonstration of the atomic bomb was a past event. Just observe the parallelism marker here :
A number of innovations shaped the course of the decade long world war II, however the invention that was the most important among all inventions were was the atomic bomb that demonstrated the superiority of firepower of allied forces.

Clause-1:A number of innovations shaped the course of the decade long world war II
Clause-2: The invention that was the most important among all inventions was the atomic bomb that demonstrated the superiority of firepower of allied forces.

Here, two clauses were combined to form one single sentence.
I was told that two clauses can be combined to write a single sentence with prepostion preceded by a comma. Only prepositions can be as mentioned below.
For, And, Not, But, Or, Yet, So
Two clauses can also be combined with a semicolon ;


Here, in the given sentence, two clauses were combined with 'however' preceded by a comma.
My Queston: Is it right to use a comma and however to combine two clauses?
If yes, what are other words such as 'however', which can be used to combine two seperate clauses to write a single sentence?

A) were the atomic bomb that demonstrated
B) was the atomic bomb that demonstrated
C) is the atomic bomb that demonstrated
D) are the atomic bomb that demonstrated
E) had been the atomic bomb that demonstrated

This sentence is rife with errors in the non-underlined portion.

1. COMMA + HOWEVER cannot be used to connect two independent clauses.
2. decade long -- an atypical construction in which a noun (decade) is being used to modify an adjective (long) -- requires a hyphen: the decade-long WWII.
3. The invention that was most important AMONG ALL INVENTIONS seems redundant.
4. The restrictive modifier THAT demonstrated implies that there was more than one atomic bomb invented and that the SC needs to make clear which atomic bomb is being discussed. (It's akin to saying John lives in the United States THAT lies below Canada, as though there more than one United States.) Since the SC is discussing THE invention that was most important -- THE atomic bomb -- a non-restrictive modifier is needed: the atomic bomb, WHICH demonstrated the superiority...
5. world war II and allied should capitalized.

I would ignore this sentence. What is the source?

Thanks Mitch....I was intrigued with this Question also. Not that I could understand with clarity like you explained...But the word HOWEVER intrigued me.
You are fantastic

Hi Mitch,
You are very amazing. I just realize two error including 'which' should be use after the atomic bomb and "however" error. Thanks
