Answer:
A Paco no le gustan estas pinturas porque él no comprende el arte de los siglos pasados.
Explanation:
In English this means: Paco doesn't like these paintings because he doesn't understand art from past centuries. "Comprende" comes from the verb comprender, and it's the conjugation in the third person singular of the present tense. "Comprendo" is in the first person singular, "comprendes" is in the second person singular and "comprenden" is conjugated in the third person plural. The only possible option is "comprende" since Paco corresponds to the third person of the singular (he).
