A) False B) False

A) P and Q yields false, for Q is false. R yields false, for R is given as false. Since we get false OR false, the overall statement is false. B) P or Q yields true, for P is true and Q is false. R is false, for R is given as false. This gives true AND false, which is a false statement.
