What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: For all x_10, x_10 will not read a book or x_10 will make tea. For all x_10, x_10 will read a book or x_10 is an electrician. For all x_10, if x_10 were an electrician, then x_10 is a mechanic. For all x_10, x_10 will listen to a song if and only if x_10 will make tea. For all x_10, if x_10 listens to a song, then x_10 is a mechanic.
For all x_10, x_10 is an electrician or x_10 will make tea can be inferred via the universal resolution rule. For all x_10, if x_10 listens to a song, then x_10 is making tea can be inferred via the universal biconditional elimination rule. For all x_10, if x_10 makes tea, then x_10 is listening to a song can be inferred via the universal biconditional elimination rule.
