Consider the following premises. For all x_5, x_5 is not curious or x_5 is a janitor. For all x_5, x_5 will not take a plane or x_5 will read a book. There is at least one x_5 for which x_5 is curious or x_5 will take a plane. For all x_5, x_5 is not a janitor. Can we infer the following from them? If we can, name the inference rule being used: For all x_5, x_5 will not read a book.
 From the fact that there is at least one x_5 for which x_5 is curious or x_5 will take a plane, and that for all x_5, x_5 is not curious or x_5 is a janitor we can infer that there is at least one x_5 for which x_5 will take a plane or x_5 is a janitor via existential resolution. From the fact that there is at least one x_5 for which x_5 will take a plane or x_5 is a janitor, and that for all x_5, x_5 will not take a plane or x_5 will read a book we can infer that there is at least one x_5 for which x_5 is a janitor or x_5 will read a book via existential resolution. Finally, from the fact that there is at least one x_5 for which x_5 is a janitor or x_5 will read a book, and that for all x_5, x_5 is not a janitor we can infer that there is at least one x_5 for which x_5 will read a book via existential disjunctive syllogism, which contradicts that For all x_5, x_5 will not read a book. Therefore, the answer is no.
