Question 976349: INSTRUCTIONS: Select the conclusion that follows in a single step from the given premises.
Given the following premises:
1. ∼D ∨ ∼T
2. D ∨ (∼T • ∼R)
3. D

A. (D ∨ ∼T) • (D ∨ ∼R) 2, Dist

B. (D ∨ ∼T) • R 2, Assoc

C. D ∨ T 1, DN

D. ∼T 1, 3, DS

E. ∼T • ∼R 2, 3, DS
What is the answer? I believe it is A...can somebody clarify?

A is true. So is D. The others are false. So either A or D could be a conclusion. If they want a single premise, then go with A.
