Consider the following premises. For all x_10, x_10 will play squash or x_10 will climb a mountain. For all x_10, if x_10 climbs a mountain, then x_10 is a soldier. There is at least one x_10 for which x_10 will not write a letter or x_10 is a janitor. For all x_10, if x_10 were a soldier, then x_10 is writing a letter. For all x_10, if x_10 plays squash, then x_10 is a soldier. Can we infer the following from them? For all x_10, neither x_10 will make tea nor x_10 is a janitor.
That contradicts the premises. Therefore the answer is no.
