Consider the following premises. Barbara is a police officer or it is raining. For all x_10, x_10 will play tennis or x_10 will not work. Barbara is not a police officer or Charles is working. If it rains, then Charles is playing tennis. Can we infer the following from them? Charles is not playing tennis.
 From the fact that for all x_10, x_10 will play tennis or x_10 will not work we can infer that for all x_10, if x_10 works, then x_10 is playing tennis. From the fact that for all x_10, if x_10 works, then x_10 is playing tennis we can infer that if Charles works, then Charles is playing tennis. From the fact that Barbara is a police officer or it is raining, and that Barbara is not a police officer or Charles is working we can infer that it is raining or Charles is working. Finally, from the fact that if it rains, then Charles is playing tennis, that if Charles works, then Charles is playing tennis, and that it is raining or Charles is working we can infer that Charles is playing tennis, which contradicts that Charles is not playing tennis. Therefore, the answer is no.
