Consider the following premises. Jennifer is not climbing a mountain. If Richard reads a book, then it is late. If Susan drives a car, then John is a carpenter. If John were a carpenter, then Jennifer is climbing a mountain. If it is late, then Susan is driving a car. Can we infer the following from them? If we can, name the inference rule being used: Richard is reading a book.
 From the fact that if John were a carpenter, then Jennifer is climbing a mountain, and that Jennifer is not climbing a mountain we can infer that John is not a carpenter via modus tollens. From the fact that if it is late, then Susan is driving a car, and that if Susan drives a car, then John is a carpenter we can infer that if it is late, then John is a carpenter via transitivity. From the fact that if it is late, then John is a carpenter, and that John is not a carpenter we can infer that it is not late via modus tollens. Finally, from the fact that if Richard reads a book, then it is late, and that it is not late we can infer that Richard is not reading a book via modus tollens, which contradicts that Richard is reading a book. Therefore, the answer is no.
