Consider the following premises. For all x_7, x_7 will sleep and x_7 will read a book. There is at least one x_7 for which x_7 will make tea if and only if x_7 will play a game. For all x_7, if x_7 plays a game, then x_7 is not sleeping. Can we infer the following from them? For all x_7, x_7 will make tea.
 From the fact that for all x_7, x_7 will sleep and x_7 will read a book we can infer that for all x_7, x_7 will sleep. From the fact that for all x_7, if x_7 plays a game, then x_7 is not sleeping, and that for all x_7, x_7 will sleep we can infer that for all x_7, x_7 will not play a game. Finally, from the fact that there is at least one x_7 for which x_7 will make tea if and only if x_7 will play a game, and that for all x_7, x_7 will not play a game we can infer that there is at least one x_7 for which x_7 will not make tea, which contradicts that For all x_7, x_7 will make tea. Therefore, the answer is no.
