Consider the following premises. p_1 <-> q_24. p_1 <-> t. ~q_24. forall x: T_3(x). Can we infer T_3(d) from them? If possible, name the inference rules being used at each step.
 From p_1 <-> q_24, ~q_24 we can infer ~p_1 via biconditional elimination. From p_1 <-> t, ~p_1 we can infer ~t via biconditional elimination. Finally, from forall x: T_3(x) we can infer T_3(d) via universal instantiation. Therefore, the answer is yes.
