Consider the following premises. For all x_14, x_14 is not an astronaut. It is windy. Linda is an astronaut if and only if Susan is a sailor. Can we infer the following from them? It is windy and Susan is not a sailor.
 From the fact that for all x_14, x_14 is not an astronaut we can infer that Linda is not an astronaut. From the fact that Linda is an astronaut if and only if Susan is a sailor, and that Linda is not an astronaut we can infer that Susan is not a sailor. Finally, from the fact that it is windy, and that Susan is not a sailor we can infer that it is windy and Susan is not a sailor. Therefore, the answer is yes.
