Consider the following premises. For all x_4, x_4 is not excited or x_4 will play tennis. There is at least one x_4 for which x_4 will not drink water. For all x_4, if x_4 were fast, then x_4 is drinking water. For all x_4, x_4 is excited or x_4 is fast. Can we infer the following from them? For all x_4, x_4 will not play tennis.
 From the fact that for all x_4, if x_4 were fast, then x_4 is drinking water, and that there is at least one x_4 for which x_4 will not drink water we can infer that there is at least one x_4 for which x_4 is not fast. From the fact that for all x_4, x_4 is excited or x_4 is fast, and that for all x_4, x_4 is not excited or x_4 will play tennis we can infer that for all x_4, x_4 is fast or x_4 will play tennis. Finally, from the fact that for all x_4, x_4 is fast or x_4 will play tennis, and that there is at least one x_4 for which x_4 is not fast we can infer that there is at least one x_4 for which x_4 will play tennis, which contradicts that For all x_4, x_4 will not play tennis. Therefore, the answer is no.
