Let C be the set of movie critics, let M be the set of movies that have ever been released, and let R(c, m) be "movie critic has reviewed movie m". Rewrite each of the following statements informally. a.) ∃c ∈ c, ∃d ∈ c, and ∃m ∈ M such that c ≠ d and R(c, m) ∧ R(d, m) b.) ∃c ∈ C and ∃d ∈ C such that c ≠ ? and  ∀m ∈ M, R(c, m) → ?(d, m)
