Consider the following premises. For all x_14, x_14 will not climb a mountain or x_14 is fast. For all x_14, x_14 will climb a mountain or x_14 will take a plane. For all x_14, if x_14 were fast, then x_14 is cooking. There is at least one x_14 for which x_14 will cook or x_14 will not take a plane. Can we infer the following from them? There is at least one x_14 for which x_14 will cook or x_14 is a taxi driver.
 From the fact that there is at least one x_14 for which x_14 will cook or x_14 will not take a plane we can infer that there is at least one x_14 for which if x_14 takes a plane, then x_14 is cooking. From the fact that for all x_14, x_14 will climb a mountain or x_14 will take a plane, and that for all x_14, x_14 will not climb a mountain or x_14 is fast we can infer that for all x_14, x_14 will take a plane or x_14 is fast. From the fact that there is at least one x_14 for which if x_14 takes a plane, then x_14 is cooking, that for all x_14, if x_14 were fast, then x_14 is cooking, and that for all x_14, x_14 will take a plane or x_14 is fast we can infer that there is at least one x_14 for which x_14 will cook. Finally, from the fact that there is at least one x_14 for which x_14 will cook we can infer that there is at least one x_14 for which x_14 will cook or x_14 is a taxi driver. Therefore, the answer is yes.
