Consider the following premises. For all x_7, x_7 is not a server. If it snows, then Jennifer is a server. If Jennifer were a server, then it is snowing. Can we infer the following from them? It is not snowing.
 From the fact that for all x_7, x_7 is not a server we can infer that Jennifer is not a server. From the fact that if it snows, then Jennifer is a server, and that if Jennifer were a server, then it is snowing we can infer that it is snowing if and only if Jennifer is a server. Finally, from the fact that it is snowing if and only if Jennifer is a server, and that Jennifer is not a server we can infer that it is not snowing. Therefore, the answer is yes.
