Question

course challenge
everyone in most psychiatric circles agree that daily exercise can enhance mental well - being.
choose 1 answer:
a no change
b agrees
c have agreed
d were agreeing

Explanation:

The subject "Everyone" is singular. In English grammar, a singular subject requires a singular verb. "Agree" is plural, "have agreed" (plural present - perfect) and "were agreeing" (plural past - continuous) are also incorrect for a singular subject. "Agrees" is the correct singular present - tense verb form.

Answer:

B. agrees
