Consider the following premises. There is at least one x_17 for which if x_17 cooks, then x_17 is not a sailor. For all x_17, x_17 is an astronaut or x_17 is a sailor. For all x_17, x_17 is not an astronaut. For all x_17, if x_17 cooks, then x_17 is a poet. For all x_17, if x_17 were a poet, then x_17 is cooking. Can we infer the following from them? For all x_17, x_17 is a poet.
 From the fact that for all x_17, if x_17 were a poet, then x_17 is cooking, and that for all x_17, if x_17 cooks, then x_17 is a poet we can infer that for all x_17, x_17 is a poet if and only if x_17 will cook. From the fact that for all x_17, x_17 is an astronaut or x_17 is a sailor, and that for all x_17, x_17 is not an astronaut we can infer that for all x_17, x_17 is a sailor. From the fact that for all x_17, x_17 is a poet if and only if x_17 will cook we can infer that for all x_17, if x_17 were a poet, then x_17 is cooking. From the fact that there is at least one x_17 for which if x_17 cooks, then x_17 is not a sailor, and that for all x_17, x_17 is a sailor we can infer that there is at least one x_17 for which x_17 will not cook. Finally, from the fact that for all x_17, if x_17 were a poet, then x_17 is cooking, and that there is at least one x_17 for which x_17 will not cook we can infer that there is at least one x_17 for which x_17 is not a poet, which contradicts that For all x_17, x_17 is a poet. Therefore, the answer is no.
