Question

the root fic or fac means do or make. what does the word prolific mean?
productive or fruitful
helpful or cooperative
pushy or assertive

Explanation:

To determine the meaning of "prolific", we use the root "fic/fac" which means "do" or "make". "Prolific" relates to producing or making a lot (e.g., a prolific writer produces many works). "Productive or fruitful" matches this as it implies creating or yielding much. "Helpful or cooperative" refers to assistance/collaboration, not production. "Pushy or assertive" refers to forcefulness, not production.

Answer:

A. productive or fruitful
