Consider the following premises. Jennifer is a police officer. Patricia is reading a book if and only if Jessica is drinking water. For all x_16, x_16 will not read a book. Can we infer the following from them? Jessica is drinking water.
 From the fact that for all x_16, x_16 will not read a book we can infer that Patricia is not reading a book. Finally, from the fact that Patricia is reading a book if and only if Jessica is drinking water, and that Patricia is not reading a book we can infer that Jessica is not drinking water, which contradicts that Jessica is drinking water. Therefore, the answer is no.
