Discussion
(P v Q) ^ (P→R) ^ (Q → R) is equivalent to
Answer: C
Correct answer: R
Both P and Q lead to R, and \( P \lor Q \) guarantees that one of them holds, so R follows in either case. This is the constructive dilemma with the same conclusion on both branches, which collapses it to a proof of R. Neither P nor Q individually can be concluded, since the premises do not say which of them is true.
