MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. If the statement is true for all sets A and B, answer ʺtrue.ʺ If it is not true for all sets A and B, answer ʺfalse.ʺ Assume that A ≠ ∅, U ≠ ∅, and A ⊂ U. 10) B ⊆ B A) True 11) ∅ ⊄ ∅ A) True Let U = {q, r, s, t, u, v, w, x, y, z} A = {q, s, u, w, y} B = {q, s, y, z} C = {v, w, x, y, z}. List the elements in the set. 12) (A ∩ B)ʹ A) {t, v, x} C) {s, u, w} Construct a Venn diagram illustrating the
