Consider the following premises. If it is cold, then it is windy. If it is windy, then William is sad. For all x_14, x_14 is not sad. Can we infer the following from them? It is cold.
 From the fact that for all x_14, x_14 is not sad we can infer that William is not sad. From the fact that if it is windy, then William is sad, and that William is not sad we can infer that it is not windy. Finally, from the fact that if it is cold, then it is windy, and that it is not windy we can infer that it is not cold, which contradicts that It is cold. Therefore, the answer is no.
