Consider the following premises. T(j) <-> q_3. forall x: R(x) -> T(x). Can we infer R(j) -> q_3 from them? If possible, name the inference rules being used at each step.
 From forall x: R(x) -> T(x) we can infer R(j) -> T(j) via universal instantiation. From T(j) <-> q_3 we can infer T(j) -> q_3 via biconditional elimination. Finally, from R(j) -> T(j), T(j) -> q_3 we can infer R(j) -> q_3 via transitivity. Therefore, the answer is yes.
