I guess it is sequencing of events. Thomas Edison was an anonymous student and scientist first and later he was a popular and respected inventor. When events occur in a sequence, the former event in the sequence uses a past-perfect tense and later uses a past tense.

I disagree with OA, and I think the source can have good questions except this SC question.

"before" already indicates the time sequence

The usage of before indicates a clear time frame. Can some expert tell what is wrong in A?

Re: Before Thomas Edison became the popular and respected inventor known a [#permalink]
Shouldn't "A" be the correct option here? We do not need past perfect when a marker such as "before" is already present.

Yes, option D is wrong because of the unnecessary use of past perfect. The verb "was" in option A is alright - but the part "known as Thomas Edison" is redundant. None of the given options is correct.

That's a weird question, which doesn't have any fully correct answers imo. I chose A, even though it's redundant.

Re: Before Thomas Edison became the popular and respected inventor known a [#permalink]
Before Thomas Edison became the popular and respected inventor known as Thomas Edison, he was an anonymous student and scientist.

A. Before Thomas Alva Edison became the popular and respected inventor known as Thomas Edison, he was
B. Before he had been the popular and respected inventor, Thomas Edison he was
C. Thomas Alva Edison has been popular and respected inventor, Thomas Edison, after such time as he was
D. Before he became the popular and respected inventor, Thomas Edison had once been
E. Thomas Alva Edison, before he was the popular and respected inventor, Thomas Edison, had been

Could you please explain why correct option is D not A?

I think the problem is similar to this one

In the minds of many people living in England, before Australia was Australia, it was the antipodes, the opposite pole to civilization, an obscure and unimaginable place that was considered the end of the world.

(A) before Australia was Australia, it was the antipodes

(B) before there was Australia, it was the antipodes

(C) it was the antipodes that was Australia

(D) Australia was what was the antipodes

(E) Australia was what had been known as the antipodes

I think A is perfectly fine
Also D is not correct.
D. Before he became the popular and respected inventor, Thomas Edison had once been -- its not a modifier as it has a subject, and so it cant modify Thomas Edison. Its illogical as he can refer to somebody else.

hey!

Before Thomas Edison became the popular and respected inventor known as Thomas Edison, he was an anonymous student and scientist.

D. Before he became the popular and respected inventor, Thomas Edison had once been

had refers to what Thomas Edison was at first( an anonymous student and scientist) before he became popular and a respected inventor!!

compared to option A option D is more concise

and "he" cannot refer to any-other antecedent except "Thomas Edison", as no other logical antecedent exists in the sentence.

what do you say?

My take on eliminating option D.
1. "Before" already marks the time sequence
2. Edison had once been anonymous. Does this mean he had been anonymous before becoming an inventor? Or perhaps, before becoming an inventor, he had been anonymous, then he was famous/popular and then he became inventor?

so.. before does mark a time sequence but including a had depends on the sentence .... its also okay to have had in the same sentence that contains a "before" and a "after" (after, before, by the end) are all major past perfect indicators:

( the site explains when its okay to omit had and when it is not okay )

what option D means is:

1st Thomas Edison was an anonymous student and scientist--- we are using had for the first of the two things he was !
2nd he became a popular and a respected inventor

and He was all those things in the past so we can use past perfect tense.

basically what the link says is that when we have two "action events" in the past its okay to skip the "had"
but when we are talking about any "experiences" then its important to include a had!
