Based on the words in parentheses, which one of the following sentences needs a past participle? A. They just (finish) breakfast when the phone rang. C. Last night, parents (gather) at the elementary school. D. We have (eat) late every night.
All three of them would need a form that looks like past participle (-ed at the end) but only in D it is a past participle (because it follows "have") - in the other options it is a past form of the verb.
