Consider the following premises. For all x_8, x_8 will go running or x_8 is an astronaut. Susan is not a poet. If William goes running, then Susan is a poet. Can we infer the following from them? William is not an astronaut.
 From the fact that for all x_8, x_8 will go running or x_8 is an astronaut we can infer that William is running or William is an astronaut. From the fact that if William goes running, then Susan is a poet, and that Susan is not a poet we can infer that William is not running. Finally, from the fact that William is running or William is an astronaut, and that William is not running we can infer that William is an astronaut, which contradicts that William is not an astronaut. Therefore, the answer is no.
