Consider the following premises. w -> ~R_16(a_16). forall x_16: R_16(x_16) and S_16(x_16). w or t. Can we infer t from them? If possible, name the inference rules being used at each step.
 From forall x_16: R_16(x_16) and S_16(x_16) we can infer R_16(a_16) and S_16(a_16) via universal instantiation. From R_16(a_16) and S_16(a_16) we can infer R_16(a_16) via simplification. From w -> ~R_16(a_16), R_16(a_16) we can infer ~w via modus tollens. Finally, from w or t, ~w we can infer t via disjunctive syllogism. Therefore, the answer is yes.
