Consider the following premises. For all x_10, if x_10 were rich, then x_10 is bored. If James drives a car, then Jennifer is rich. If Jennifer were bored, then Sarah is taking a plane. Can we infer the following from them? If we can, name the inference rule being used: If James drives a car, then Sarah is taking a plane.
 From the fact that for all x_10, if x_10 were rich, then x_10 is bored we can infer that if Jennifer were rich, then Jennifer is bored via universal instantiation. From the fact that if Jennifer were rich, then Jennifer is bored, and that if Jennifer were bored, then Sarah is taking a plane we can infer that if Jennifer were rich, then Sarah is taking a plane via transitivity. Finally, from the fact that if James drives a car, then Jennifer is rich, and that if Jennifer were rich, then Sarah is taking a plane we can infer that if James drives a car, then Sarah is taking a plane via transitivity. Therefore, the answer is yes.
