Answer:
went
Explanation:
In the sentence, there are only two verbs: went and is. Is, which comes from the verb to be, expresses a state or a condition, therefore it is not an action verb. In contrast, went, which comes from the verb to go, is an action verb because it expresses movement, it describes a physical action. Action verbs are those expressing mental or physical action like going, running, giving, thinking, talking and crying.
