Question

El colegio __________ (participar) en deportes

a) participa
b) partcipamos
c) participo
d) participais

Answer 1

The answer is a, participa.

Answer 2

The correct answer is

a) participa

This makes the sentence:
El colegio participa en deportes.

This is because colegio is a singular noun, which means it has the same verb conjugation as the subject pronouns él, ella, and usted.
