What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_2 for which if x_2 makes tea, then x_2 is running. For all x_2, x_2 will climb a mountain if and only if x_2 will go running. For all x_2, if x_2 plays squash, then x_2 is making tea.
