Consider the following premises. For all x_10, if x_10 were bored, then x_10 is playing tennis. For all x_10, x_10 is bored. For all x_10, if x_10 drives a car, then x_10 is an astronaut. For all x_10, x_10 will drive a car. For all x_10, if x_10 plays tennis, then x_10 is taking a plane. Can we infer the following from them? If we can, name the inference rule being used: For all x_10, x_10 is an astronaut.
 From the fact that for all x_10, if x_10 were bored, then x_10 is playing tennis, and that for all x_10, x_10 is bored we can infer that for all x_10, x_10 will play tennis via universal modus ponens. Finally, from the fact that for all x_10, if x_10 drives a car, then x_10 is an astronaut, and that for all x_10, x_10 will drive a car we can infer that for all x_10, x_10 is an astronaut via universal modus ponens. Therefore, the answer is yes.
