Explanation: Just to elaborate a little on the answer, it can be added that in this exercise you have been asked to use ONLY the verbs in brackets. You are not supposed to add other verbs, but to conjugate the ones that they have provided for you. I have used the present continuous (or progressive) in those sentences (3, 4, 5) that refer to actions or conditions that are happening in the present and/or may continue in the future—for instance, that "books are missing" from the library. In other examples I have used the simple present (2, 6), since the sentences refer to repeated actions—Sarah "watches" her show every evening. And I have used the simple future (will) and again the present continuous (specifically the form "be going to") to predict a future event (7, 1) and to talk about future plans and intentions (8)—for instance, that the speaker predicts that Harry "will live" when the other person gets back.
