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 is a scientist. For all x_10, if x_10 makes tea, then x_10 is listening to a song. For all x_10, x_10 is a cashier. For all x_10, x_10 will make tea.
For all x_10, x_10 will listen to a song can be inferred via the universal modus ponens rule. For all x_10, x_10 is a scientist and x_10 is a cashier can be inferred via the universal conjunction rule. For all x_10, x_10 is a scientist and x_10 will make tea can be inferred via the universal conjunction rule. For all x_10, x_10 is a cashier and x_10 is a scientist can be inferred via the universal conjunction rule. For all x_10, x_10 is a cashier and x_10 will make tea can be inferred via the universal conjunction rule. For all x_10, x_10 will make tea and x_10 is a scientist can be inferred via the universal conjunction rule. For all x_10, x_10 will make tea and x_10 is a cashier can be inferred via the universal conjunction rule.
