A. was the invention of the electric motor and the discovery of alternating current by Nikola Tesla,
B. was the invention of the electric motor, the discovery of alternating current by Nikola Tesla, who was
C. had been invention of the electric motor and the discovery of alternating current by Nikola Tesla, who was
D. were the invention of the electric motor, as well as the discovery of alternating current, by Nikola Tesla,
E. were the invention of the electric motor and the discovery of alternating current by Nikola Tesla,



The subject in this particular sentence is plural ( the invention of the electric motor and the discovery of alternating current)
So a plural verb is correct so A,B are out
Had been is wrong in C as there is no timeline in the sentence
D is incorrect as it used additive phrase as well as which does not have any effect on the subject which here is singular so a singular verb should come .
E is the correct answer

One invention is compared to two other inventions. Use of 'was' is wrong in original sentence.
Option B is also out.
'Had been' is choice C is wrong as it is not an event that happened in the past and is ongoing. It is already completed
In D, 'were' is used along with 'as well as' which is wrong.
Option E is correct as it addresses the problem of S-V agreement.

I still do not understand how were is correct and was isn't.
Why "invention" is not a subject here??
if it was inventions then we might have used were.

for eg. The day of Raj and Ricky's graduation is special. --> correct
The day of Raj and Ricky's graduation are special. --> dont think correct
The days of Raj and Ricky's graduation are special. --> correct

(A) was the invention of the electric motor and the discovery of alternating current by Nikola Tesla,

(B) was the invention of the electric motor, the discovery of alternating current by Nikola Tesla, who was

(C) had been invention of the electric motor and the discovery of alternating current by Nikola Tesla, who was

(D) were the invention of the electric motor, as well as the discovery of alternating current, by Nikola Tesla,

(E) were the invention of the electric motor and the discovery of alternating current by Nikola Tesla,


Solution


In scanning the answer choices for decision points, you should first notice the subject/verb agreement choice between “was”/”were” and the tense choice with “had been”.

While the original sentence might sound correct to your grammar “ear”, it is actually wrong.

Anytime you have a subject/verb agreement issue, you need to determine the proper subject for the verb.

In this inverted sentence, the subject comes after the verb, so it is easy to miss that the core sentence is really: “the invention of the electric motor and the discovery of alternating current WERE no less impressive than the invention of the light bulb..”

As a result you can eliminate (A) and (B) as they incorrectly use the singular verb “was.”

In (C) the past perfect “had been” is incorrect as there is no point in the past before which those inventions took place.

For (D), the subject is the singular “the invention of the electric motor” so the plural verb “were” is wrong.

Because “the discovery of alternating current” is connected with “as well as” instead of “and” the subject is no longer plural and this choice too suffers from an error of subject/verb agreement.

Correct answer is (E).
