No books, notes, calculators, or collaboration. 1) (14 pts) Provide a justification (rule and line numbers) for each line of this proof: 1 (u M) (u / P Q) 2 (u P ) (u R) 3 (u / P Q) (u M) 4 (u P Q) (u / M) 5 u M N 6 u P 7 (u P ) (u Q) 8 u P Q 9 u / M 10 (u M) & (u N) 11 u M 12 (u M) & (u / M) 13 u / P 14 u R 15 (u M N) (u R) 2) (10 pts) Assume D is a set. Circle T if the assertion is always true (a tautology). Circle F if the assertion is always false (a contradiction). Circle? if the assertion is sometimes true and sometimes false (depending on what D is). (You do not need to show your work.) SCORE = # of correct answers minus # of wrong answers. T F? x, (x = x) T F? x, (x x) T F? x, (x = x) T F? x, (x x) (Parts left blank will be ignored.)
