Consider the following premises. p_16 <-> t_1. r. p -> t_1. ~p_16. Can we infer p from them? If possible, name the inference rules being used at each step.
 From p_16 <-> t_1, ~p_16 we can infer ~t_1 via biconditional elimination. Finally, from p -> t_1, ~t_1 we can infer ~p via modus tollens, which contradicts p. Therefore, the answer is no.
