Yes. If all the question's parts are true, then the answer is true. If all the question's parts are false, then the answer is false. If one of the question's parts is false and the rest true, then the answer is false. Logically, this is illustrated below using: A = True, B = True, C = True, D = False, E = False, F = False A and B and C = True D and E and F = False A and B and D = False If you add NOT, it's a bit more complicated. A and NOT(D) = True and True = True NOT(D) and D = True and False = False NOT(A) and NOT(B) = False and False = False Using OR adds another layer of complexity. A OR NOT(E) = True OR True = True NOT(D) OR D = True OR False = False NOT(A) OR NOT(B) = False OR False = False Logic is easy once you understand the rules.
