Consider the following premises. For all z_3, z_3 will work or z_3 is not a sailor. For all z_3, if z_3 climbs a mountain, then z_3 is a sailor. For all z_3, if z_3 works, then z_3 is climbing a mountain. Can we infer the following from them? If we can, name the inference rule being used: The fact that Jennifer were a sailor does not imply that Jennifer is working.
That contradicts the premises. Therefore the answer is no.
