Consider the following premises. There is at least one x_10 for which x_10 is not a carpenter or x_10 is a mechanic. For all x_10, x_10 is a mechanic if and only if x_10 will play tennis. For all x_10, x_10 will play tennis if and only if x_10 will sleep. For all x_10, x_10 is a carpenter or x_10 will sleep. 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, x_10 is a mechanic if and only if x_10 will play tennis we can infer that for all x_10, if x_10 were a mechanic, then x_10 is playing tennis. From the fact that for all x_10, x_10 will play tennis if and only if x_10 will sleep we can infer that for all x_10, if x_10 sleeps, then x_10 is playing tennis. From the fact that for all x_10, x_10 is a carpenter or x_10 will sleep, and that there is at least one x_10 for which x_10 is not a carpenter or x_10 is a mechanic we can infer that there is at least one x_10 for which x_10 will sleep or x_10 is a mechanic. Finally, from the fact that for all x_10, if x_10 sleeps, then x_10 is playing tennis, that for all x_10, if x_10 were a mechanic, then x_10 is playing tennis, and that there is at least one x_10 for which x_10 will sleep or x_10 is a mechanic 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.
