Since the very beginning of the sentence, the phrase <em>last night</em> indicates that the action in the sentence was performed in the past. In other words, the action described in the sentence has already happened. For this reason, the verb that completes the sentence with the appropiate verb tense has to be a verb in past tense. Thus, the correct answer is revised, which is the only verb from the list that is in past tense.
