Question

complete the sentence
____________________, an impressive baseball player, but he was also a humanitarian activist who was heavily involved in relief efforts for the 1972 earthquake in nicaragua.
roberto clemente was not only
not only was roberto clemente

Explanation:

This is a sentence completion question focusing on correct correlative conjunction structure and inversion. The phrase "not only...but also..." is used here. When "not only" is placed at the start of a clause for emphasis, subject-verb inversion is required, matching the structure of the second option. The first option would create a grammatical error if placed in the blank, as it would result in a redundant subject reference.

Answer:

Not only was Roberto Clemente
