Prove: (P T) (RS),Q (U T),U P,S |- Q R

1. First, by assuming Q and showing R.

2. Then, without assuming Q (so you must directly show Q R) and using the Logic Daemon to check your proof. Solution. 1. (1) (P T) (RS) A

(2) Q (U T) A

(3) U P A

(4) S A

(5) Q A

. . .

(k) R [rule of inference]

2. Include a clear screen shot of the correct proof checked by the Logic Daemon.
