Consider the following premises. For all x_22, x_22 is fast if and only if x_22 will drive a car. For all x_22, if x_22 climbs a mountain, then x_22 is fast. For all x_22, if x_22 were a poet, then x_22 is climbing a mountain. For all x_22, x_22 is a scientist or x_22 is a poet. There is at least one x_22 for which x_22 is not a scientist. Can we infer the following from them? There is at least one x_22 for which x_22 will drive a car.
 From the fact that for all x_22, x_22 is a scientist or x_22 is a poet, and that there is at least one x_22 for which x_22 is not a scientist we can infer that there is at least one x_22 for which x_22 is a poet. From the fact that for all x_22, if x_22 were a poet, then x_22 is climbing a mountain, and that for all x_22, if x_22 climbs a mountain, then x_22 is fast we can infer that for all x_22, if x_22 were a poet, then x_22 is fast. From the fact that for all x_22, x_22 is fast if and only if x_22 will drive a car we can infer that for all x_22, if x_22 were fast, then x_22 is driving a car. From the fact that for all x_22, if x_22 were a poet, then x_22 is fast, and that there is at least one x_22 for which x_22 is a poet we can infer that there is at least one x_22 for which x_22 is fast. Finally, from the fact that for all x_22, if x_22 were fast, then x_22 is driving a car, and that there is at least one x_22 for which x_22 is fast we can infer that there is at least one x_22 for which x_22 will drive a car. Therefore, the answer is yes.
