Consider the following premises. Linda is a sailor or Robert is not a scientist. Robert is a scientist if and only if Sarah is an artist. Linda is not a sailor. Can we infer the following from them? If we can, name the inference rule being used: Sarah is an artist.
 From the fact that Linda is a sailor or Robert is not a scientist we can infer that if Robert were a scientist, then Linda is a sailor via rewriting. From the fact that if Robert were a scientist, then Linda is a sailor, and that Linda is not a sailor we can infer that Robert is not a scientist via modus tollens. Finally, from the fact that Robert is a scientist if and only if Sarah is an artist, and that Robert is not a scientist we can infer that Sarah is not an artist via biconditional elimination, which contradicts that Sarah is an artist. Therefore, the answer is no.
