1) ~P ∨ S ≡  P → S   ( if P true then S must be true )

2) ~T ∨ ( S ∧ R )   ≡  T → ( S ∧ R ) ( if T true then S and R both must be true )

3) ~Q ∨ R ≡  Q → R   ( if Q true then R must be true )

4) P ∨ Q ∨ T ( either P is true or Q is true or T is true ===> either S is true ( due to P ) or R is true ( due to Q ) or both true ( due to T ) )

∴ S ∨ R is conclusion
