What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_14, x_14 will not sleep. For all x_14, x_14 is a taxi driver if and only if x_14 will sleep. James is a taxi driver if and only if it is cloudy.
If James were a taxi driver, then it is cloudy. If it is cloudy, then James is a taxi driver. For all x_14, if x_14 were a taxi driver, then x_14 is sleeping. For all x_14, if x_14 sleeps, then x_14 is a taxi driver. For all x_14, x_14 is not a taxi driver.
