What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 will drink water or x_8 will take a plane. There is at least one x_8 for which x_8 will make tea or x_8 will not work. For all x_8, if x_8 takes a plane, then x_8 is making tea. For all x_8, if x_8 drinks water, then x_8 is working.
There is at least one x_8 for which if x_8 works, then x_8 is making tea.
