Consider the following premises. It is late. If Jennifer were a sailor, then it is cold. If Mary drinks water, then it is not late. If it is cold, then Mary is drinking water. Can we infer the following from them? Jennifer is a sailor.
 From the fact that if Mary drinks water, then it is not late, and that it is late we can infer that Mary is not drinking water. From the fact that if it is cold, then Mary is drinking water, and that Mary is not drinking water we can infer that it is not cold. Finally, from the fact that if Jennifer were a sailor, then it is cold, and that it is not cold we can infer that Jennifer is not a sailor, which contradicts that Jennifer is a sailor.
