If -1 is in the set, which of the following must also be in the text? I -3, II 1, III 5, A) I only, B) II only, C) I and II only, D) II and III only, E) I,II, and III. ANSWER D.I see that II is in the set. I don't see that 5 is in the set, because I don't understand how large the set is. Wh doesn't the set stop at 1? Who is to say that it continues?
