Answer:
The prefix that would best complete the blank in the following sentence is multi.
Naama played the violin, the piano, and the guitar; everyone was impressed by how multitalented she was.
Step-by-step explanation:
Prefixes are a type of affix made of letters we add at the beginning of a word to create a new one with a change of meaning. The prefix conveys meaning. In this case, the prefix multi- means several or many, so whenever we add this prefix to an adjective or noun, we are adding that new meaning to the original adjective or noun.
In this case, multitalented is a person who has several talents.
