Consider the following premises. For all x_10, x_10 is an astronaut or x_10 is a carpenter. For all x_10, if x_10 were a carpenter, then x_10 is a sailor. For all x_10, if x_10 were a sailor, then x_10 is making tea. There is at least one x_10 for which x_10 will make tea if and only if x_10 will play tennis. For all x_10, if x_10 were an astronaut, then x_10 is making tea. Can we infer the following from them? For all x_10, x_10 will not play tennis.
 From the fact that for all x_10, if x_10 were a carpenter, then x_10 is a sailor, and that for all x_10, if x_10 were a sailor, then x_10 is making tea we can infer that for all x_10, if x_10 were a carpenter, then x_10 is making tea. From the fact that for all x_10, if x_10 were an astronaut, then x_10 is making tea, that for all x_10, if x_10 were a carpenter, then x_10 is making tea, and that for all x_10, x_10 is an astronaut or x_10 is a carpenter we can infer that for all x_10, x_10 will make tea. From the fact that there is at least one x_10 for which x_10 will make tea if and only if x_10 will play tennis we can infer that there is at least one x_10 for which if x_10 makes tea, then x_10 is playing tennis. Finally, from the fact that there is at least one x_10 for which if x_10 makes tea, then x_10 is playing tennis, and that for all x_10, x_10 will make tea we can infer that there is at least one x_10 for which x_10 will play tennis, which contradicts that For all x_10, x_10 will not play tennis. Therefore, the answer is no.
