Consider the following premises. For all x_10, x_10 is fast. For all x_10, if x_10 were a mechanic, then x_10 is not fast. There is at least one x_10 for which if x_10 were rich, then x_10 is a mechanic. For all x_10, x_10 will drive a car if and only if x_10 is rich. Can we infer the following from them? For all x_10, x_10 will drive a car.
 From the fact that for all x_10, if x_10 were a mechanic, then x_10 is not fast, and that for all x_10, x_10 is fast we can infer that for all x_10, x_10 is not a mechanic. From the fact that there is at least one x_10 for which if x_10 were rich, then x_10 is a mechanic, and that for all x_10, x_10 is not a mechanic we can infer that there is at least one x_10 for which x_10 is not rich. Finally, from the fact that for all x_10, x_10 will drive a car if and only if x_10 is rich, and that there is at least one x_10 for which x_10 is not rich we can infer that there is at least one x_10 for which x_10 will not drive a car, which contradicts that For all x_10, x_10 will drive a car. Therefore, the answer is no.
