Consider the following premises. For all x_6, if x_6 were a lawyer, then x_6 is a scientist. For all x_6, if x_6 drives a car, then x_6 is taking a plane. For all x_6, x_6 is a lawyer or x_6 will not take a plane. Can we infer the following from them? For all x_6, if x_6 drives a car, then x_6 is a scientist.
 From the fact that for all x_6, x_6 is a lawyer or x_6 will not take a plane we can infer that for all x_6, if x_6 takes a plane, then x_6 is a lawyer. From the fact that for all x_6, if x_6 takes a plane, then x_6 is a lawyer, and that for all x_6, if x_6 were a lawyer, then x_6 is a scientist we can infer that for all x_6, if x_6 takes a plane, then x_6 is a scientist. Finally, from the fact that for all x_6, if x_6 drives a car, then x_6 is taking a plane, and that for all x_6, if x_6 takes a plane, then x_6 is a scientist we can infer that for all x_6, if x_6 drives a car, then x_6 is a scientist. Therefore, the answer is yes.
