Consider the following premises. Jennifer is reading a book. For all x_28, if x_28 reads a book, then x_28 is a sailor. Michael is running if and only if Sarah is a carpenter. If Mary drinks water, then Sarah is a carpenter. Michael is not running. Can we infer the following from them? Mary is drinking water.
 From the fact that for all x_28, if x_28 reads a book, then x_28 is a sailor we can infer that if Jennifer reads a book, then Jennifer is a sailor. From the fact that Michael is running if and only if Sarah is a carpenter, and that Michael is not running we can infer that Sarah is not a carpenter. From the fact that if Jennifer reads a book, then Jennifer is a sailor, and that Jennifer is reading a book we can infer that Jennifer is a sailor. Finally, from the fact that if Mary drinks water, then Sarah is a carpenter, and that Sarah is not a carpenter we can infer that Mary is not drinking water, which contradicts that Mary is drinking water. Therefore, the answer is no.
