Question

complete the sentence.
did you ___ the clown was funny?
old stop just think

Explanation:

We need to choose a verb that makes sense in the sentence "Did you ___ the clown was funny?". "old" is an adjective, "stop" would not fit semantically here (the structure "stop the clown was funny" is incorrect), "just" is an adverb. "think" is a verb that fits, as "Did you think the clown was funny?" is a grammatically and semantically correct sentence, meaning asking if the person believed the clown was funny.

Answer:

think
