Go Getter - Hammy, Max & Anna Go On A Picnic - Quantifiers

SOLVED:(a) Comparing the various rules for dealing with quantifiers in proofs, you should see a similarity between the rules for goals of the form ∀x P(x) and givens of the form ∃x P(x). What is this similarity? What about the rules for goals of the form ∃x P(x) and givens of the form ∀x P(x) ? (b) Can you think of a reason why these similarities might be expected?

Use rules of inference to show that if ∀x(P(x) ∨ Q(x)) and ∀x((¬P(x) ∧ Q(x)) → R(x)) are true, then ∀x(¬R(x) → P(x)) is also true, where the domains of all quantifiers are the same.
