Help! Propositional natural deduction proofs

Construct propositional natural deduction proofs for the following sequents and tautologies, including complete justification columns.

1. [(~M&R) &~P]&D, ~M->Q ⊢ QvT
[(BOTH ~M AND R) AND NOT P] AND D, IF NOT M THEN Q THUS Q OR T

1. | [(M&R) &~P]&D A
2. | ~M->Q A

2: ~[P v (QvZ)], (~ZvL) ->M ⊢ M
NOT (EITHER P OR ( Q OR Z)),(IF NOT Z OR L THEN M) THUS M
