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_7 for which x_7 will listen to a song. For all x_7, x_7 will make tea if and only if x_7 will sleep. For all x_7, x_7 will sleep or x_7 is a soldier. For all x_7, x_7 will not make tea.
For all x_7, if x_7 makes tea, then x_7 is sleeping. For all x_7, if x_7 sleeps, then x_7 is making tea. For all x_7, x_7 will not sleep.
