Read the given sentences and choose the verbs that agree with the nouns.
You _____ have your ticket to watch the show.

The correct answer is: Must

We usually use must to talk about obligations which come from the speaker and we generally use have (got) to when we refer to obligations that come from outside the speaker. 'You must have your ticket to watch the show', here 'must' wanted to say that it is necessary or very important that something happens.
