Consider the following premises. If it is windy, then it is sunny. It is not sunny. If it is cold, then it is windy. It is cold if and only if David is a server. Can we infer the following from them? David is a server.
 From the fact that if it is windy, then it is sunny, and that it is not sunny we can infer that it is not windy. 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. Finally, from the fact that it is cold if and only if David is a server, and that it is not cold we can infer that David is not a server, which contradicts that David is a server. Therefore, the answer is no.
