Explanation: Just to elaborate a little on the answer, it can be added that in this exercise they are asking you to use the verb ir (to go) with the preposition "a" (to) and occasionally venir (to come) in order to express future intentions and plans, some of them more immediate than others. For instance, in sentence 2 Daniel is saying that he goes (he is on his way) to the movie theater to watch a movie, and in sentence 4 Elena is saying that she is also on her way. However, in sentence 5 he is asking her where she is going that night, and in sentence 6 she is replying that she will be eating at an Italian restaurant with her roommate. In all instances, however, we have used the present tense. In some of the sentences, the verb ir has preceded an infinitive—as in option 13, "to go to dance."
