Consider the following premises. For all x_12, if x_12 were poor, then x_12 is a nurse. For all x_12, if x_12 drinks water, then x_12 is not a nurse. There is at least one x_12 for which x_12 is a nurse or x_12 will not work. For all x_12, x_12 is poor or x_12 will work. Can we infer the following from them? For all x_12, x_12 will drink water.
 From the fact that there is at least one x_12 for which x_12 is a nurse or x_12 will not work we can infer that there is at least one x_12 for which if x_12 works, then x_12 is a nurse. From the fact that for all x_12, if x_12 were poor, then x_12 is a nurse, that there is at least one x_12 for which if x_12 works, then x_12 is a nurse, and that for all x_12, x_12 is poor or x_12 will work we can infer that there is at least one x_12 for which x_12 is a nurse. Finally, from the fact that for all x_12, if x_12 drinks water, then x_12 is not a nurse, and that there is at least one x_12 for which x_12 is a nurse we can infer that there is at least one x_12 for which x_12 will not drink water, which contradicts that For all x_12, x_12 will drink water. Therefore, the answer is no.
