Consider the following premises. Michael is an artist if and only if Linda is curious. Michael is an artist if and only if Richard is a bartender. Richard is not a bartender. Can we infer the following from them? If we can, name the inference rule being used: Linda is curious.

Finally, from the fact that Michael is an artist if and only if Linda is curious, and that Michael is not an artist we can infer that Linda is not curious via biconditional elimination, which contradicts that Linda is curious. Therefore, the answer is no.
