Consider the following premises. Jessica is a sailor if and only if Jessica is a writer. Jessica is not a sailor. Jennifer is making tea if and only if Jessica is a writer. Can we infer the following from them? If we can, name the inference rule being used: Jennifer is not making tea.
 From the fact that Jessica is a sailor if and only if Jessica is a writer we can infer that if Jessica were a writer, then Jessica is a sailor via biconditional elimination. From the fact that if Jessica were a writer, then Jessica is a sailor, and that Jessica is not a sailor we can infer that Jessica is not a writer via modus tollens. Finally, from the fact that Jennifer is making tea if and only if Jessica is a writer, and that Jessica is not a writer we can infer that Jennifer is not making tea via biconditional elimination. Therefore, the answer is yes.
