Consider the following premises. There is at least one x_1 for which if x_1 were excited, then x_1 is a police officer. For all x_1, x_1 is not a police officer. For all x_1, if x_1 makes tea, then x_1 is excited. Can we infer the following from them? For all x_1, x_1 will make tea.
 From the fact that there is at least one x_1 for which if x_1 were excited, then x_1 is a police officer, and that for all x_1, x_1 is not a police officer we can infer that there is at least one x_1 for which x_1 is not excited. Finally, from the fact that for all x_1, if x_1 makes tea, then x_1 is excited, and that there is at least one x_1 for which x_1 is not excited we can infer that there is at least one x_1 for which x_1 will not make tea, which contradicts that For all x_1, x_1 will make tea. Therefore, the answer is no.
