Quinn or Raina will be valedictorian. Quinn's being valedictorian entails that she receives an A+ in Spanish. She doesn't receive an A+ in Spanish. So, Raina is valedictorian.
-Which of the following is the best translation into PL of this argument?
A) Q $ \lor $ R Q ⊃ S
∼S / R
B) Q $ \lor $ R S ⊃ Q
∼S / R
C) Q $ \lor $ R Q ≡ S
∼A / R
D) Q $ \lor $ R S ⊃ Q
∼A / R
E) Q $ \lor $ R Q ⊃ S
∼S / Q

The argument can be translated into propositional logic as: "Either Quinn (Q) or Raina (R) will be valedictorian. If Quinn is valedictorian, then she receives an A+ in Spanish (Q ⊃ S). She doesn't receive an A+ in Spanish (∼S). Therefore, Raina is valedictorian (R)."

Quinn or Raina Will Be Valedictorian ∨ \lor ∨ R Q ⊃ S ∼S / R B) Q

Quinn or Raina Will Be Valedictorian $\lor$ R Q ⊃ S
∼S / R
B) Q
