A. require scholars to credit birds with a far earlier origin than previously thought - Correct. could force a revision and could require are in parallel.

B. scholars may be required to credit birds with a far earlier origin than previously thought - Incorrect. Parallelism error and passive.

C. require a crediting by scholars of birds with a far earlier origin than previously thought - Incorrect. 'require a crediting' is awkward.

D. , compared to what was previously thought, require scholars to credit birds with a far earlier origin - Incorrect. Very wordy.

E. crediting birds with a far earlier origin than scholars had previously thought - Incorrect. Parallelism error.

I thought the word "require" in answer A should be "requires" because it refers to the discovery (singular).

The verb "require" is parallel to "force" and "alter". The base construction is as follows:

The discovery could force, alter and require....

The auxiliary verb "could" covers all the 3 main verbs "force", "alter" and "require". Hence "requires" would be wrong.
