Which sentence uses an action verb? A. Is it hard to be a clown? B. My favorite circus performers were the clowns. C. The clowns' costumes were colorful . D. We laughed at the clowns during the circus.
I believe the answer is D. 'Laughed' would be the action verb because to laugh is to do something, so it is an action. None of the other sentences have a word that would represent someone doing something.
