Select the most appropriate option to fill in the blanks.

Besides being ______ multifaceted artist, he was _____ poet, novelist, and a painter.

a, a

The most appropriate option to fill in the blanks is: a, a

Here's why:

• "Multifaceted" is an adjective with a consonant sound ("mul-ti-fa-cet-ed").
• We use the indefinite article "a" before singular nouns or adjectives with consonant sounds.
• "Poet," "novelist," and "painter" are all singular nouns.

Therefore, we need "a" before both "multifaceted artist" and "poet."
