Consider the following premises. If James were a server, then it is cold. For all x_12, x_12 will work if and only if x_12 is a server. If it is cold, then James is working. Can we infer the following from them? If we can, name the inference rule being used: If is not true that it is cold if and only if James is working.
That contradicts the premises. Therefore the answer is no.
