4. What is the most general unifier of the following pairs of wff's? If none exists, report "fail." Assume that the capital letters are constants and the lowercase letters are variables. a. P(x, y, x, 2) and P(F(w), A, F(B), w) b. Mother(x, y) and Mother(y,Father(x) c. P(x, f(x)) and Ply, y) 5. Rewrite the following proposition as unambiguous English sentences. The relevant predicates are defined as follows: Again, let's let P be a set of all people a. A(x) means "x is teaching the Al course" b. T(x) means "x is taking Al course" c. F(x) means "x has a twitter account." d. C(x) means "x likes to read." For example, the proposition 3x {P [A(x)A C(x)]} could be translated as "There is a person who is teaching and likes to read" Vx{P [T(x) → (F(x)V C(x))] ?
