Prove your answer either using a regular proof in the natural language or by giving a formal inference. In the latter case you may need to use the existential rules of inference

Let the universe consists of all people. Consider the following hypotheses: • Some students like all teachers. • No student likes any dishonest person. Using first-order logic prove that "no teacher is dishonest". Use the following predicates for your proof: S(x) denotes x is a student; T(x) denotes x is a teacher; D(x) denotes x is dishonest; L(x,y) denotes x likes y.
Which of the following models are counter-models that shows that is not a logical consequence? Select one or more: □ D = {a,b}, P¹ = {(a,b), (b, b)}, Q¹ = {b}. OD=N, P¹ = {(n,n+ 1) : n € N}, Q¹ = {n € N: n is even}, where N = {0, 1, 2,...} denotes the natural numbers. □ D = {a,b}, P¹ = {(a, a), (b,b)}, Q¹ = {a}. □ D = {a,b,c}, PI = {(a,b), (b, c), (c, a)}, Q¹ = {a,b,c}. OD=N, P¹ = {(n, 2n) : n = N}, Q¹ = {n EN:n is even}, where N = {0, 1, 2,...} denotes the natural numbers. VryP(x, y), Vr(yP(x, y) → Q(x)) ¥ VIQ(1)
