Consider the following premises. It is late. For all x_16, x_16 will read a book if and only if x_16 will climb a mountain. For all x, x will not work. Patricia is reading a book if and only if James is working. Can we infer the following from them? If we can, name the inference rule being used: If Patricia doesn't climb a mountain, then it is late.
We cannot infer that from the premises. Therefore the answer is no.
