1. Identify each of the following statements as true of false and explain your reasoning in full sentences. The domain of discourse is the integers.

(a) ∃x∀y(y > x)

(b) ∀y∃x(y > x)

2. Write the formal negation of the following statements. Your negation must not contain any explicit negation symbols.

(a) ∀x∃y(2 < x ≤ y)

(b) ∀y∃x(y > 0 → x ≤ 0)

3. Negate verbally:
(a) ”All people weigh at least 100 pounds.”

(b) ”Somebody did not see any animals in the zoo”
