Consider the following premises. For all y, y is a scientist if and only if y is a server. For all y, y is a server. Can we infer the following from them? Linda is not a scientist.
 From the fact that for all y, y is a scientist if and only if y is a server we can infer that for all y, if y were a server, then y is a scientist. Finally, from the fact that for all y, if y were a server, then y is a scientist, and that for all y, y is a server we can infer that for all y, y is a scientist, which contradicts that Linda is not a scientist. Therefore, the answer is no.
