Consider the following premises. For all x_10, x_10 will make tea if and only if x_10 will play squash. There is at least one x_10 for which x_10 will read a book if and only if x_10 will make tea. For all x_10, x_10 is a nurse. For all x_10, if x_10 reads a book, then x_10 is not a nurse. Can we infer the following from them? For all x_10, x_10 will play squash.
 From the fact that for all x_10, if x_10 reads a book, then x_10 is not a nurse, and that for all x_10, x_10 is a nurse we can infer that for all x_10, x_10 will not read a book. From the fact that there is at least one x_10 for which x_10 will read a book if and only if x_10 will make tea, and that for all x_10, x_10 will not read a book we can infer that there is at least one x_10 for which x_10 will not make tea. Finally, from the fact that for all x_10, x_10 will make tea if and only if x_10 will play squash, and that there is at least one x_10 for which x_10 will not make tea we can infer that there is at least one x_10 for which x_10 will not play squash, which contradicts that For all x_10, x_10 will play squash. Therefore, the answer is no.
