Consider the following premises. Jessica is drinking water if and only if Michael is excited. If it is cold, then Jessica is drinking water. For all x_14, x_14 is not excited. Can we infer the following from them? It is cold.
 From the fact that for all x_14, x_14 is not excited we can infer that Michael is not excited. From the fact that Jessica is drinking water if and only if Michael is excited, and that Michael is not excited we can infer that Jessica is not drinking water. Finally, from the fact that if it is cold, then Jessica is drinking water, and that Jessica is not drinking water we can infer that it is not cold, which contradicts that It is cold. Therefore, the answer is no.
