Consider the following premises. There is at least one x_19 for which x_19 is not a poet. For all x_19, x_19 is a lawyer if and only if x_19 is a bartender.

From the fact that for all x_19, if x_19 were a bartender, then x_19 is a lawyer, that for all x_19, if x_19 were an astronaut, then x_19 is a lawyer, and that for all x_19, x_19 is a bartender or x_19 is an astronaut we can infer that for all x_19, x_19 is a lawyer. From the fact that for all x_19, x_19 is a lawyer, and that there is at least one x_19 for which x_19 will play squash we can infer that some lawyers will play squash.
