Consider the following premises. There is at least one x_2 for which x_2 will take a plane or x_2 is fast. For all x_2, x_2 is not fast. For all x_2, x_2 will not take a plane or x_2 will play tennis. Can we infer the following from them? There is at least one x_2 for which x_2 will play tennis.
 From the fact that there is at least one x_2 for which x_2 will take a plane or x_2 is fast, and that for all x_2, x_2 will not take a plane or x_2 will play tennis we can infer that there is at least one x_2 for which x_2 is fast or x_2 will play tennis. Finally, from the fact that there is at least one x_2 for which x_2 is fast or x_2 will play tennis, and that for all x_2, x_2 is not fast we can infer that there is at least one x_2 for which x_2 will play tennis. Therefore, the answer is yes.
