Consider the following premises. For all x_11, if x_11 were a nurse, then x_11 is a taxi driver. For all x_11, x_11 will not drink water. For all x_11, x_11 will drink water or x_11 will make tea. For all x_11, x_11 is a cashier or x_11 is a nurse. There is at least one x_11 for which if x_11 were a cashier, then x_11 is a taxi driver. Can we infer the following from them? For all x_11, either x_11 is a taxi driver or x_11 will make tea are not true.
 From the fact that there is at least one x_11 for which if x_11 were a cashier, then x_11 is a taxi driver, that for all x_11, if x_11 were a nurse, then x_11 is a taxi driver, and that for all x_11, x_11 is a cashier or x_11 is a nurse we can infer that there is at least one x_11 for which x_11 is a taxi driver. From the fact that for all x_11, x_11 will drink water or x_11 will make tea, and that for all x_11, x_11 will not drink water we can infer that for all x_11, x_11 will make tea. Finally, from the fact that there is at least one x_11 for which x_11 is a taxi driver, and that for all x_11, x_11 will make tea we can infer that there is at least one x_11 for which x_11 is a taxi driver and x_11 will make tea, which contradicts that For all x_11, either x_11 is a taxi driver or x_11 will make tea are not true. Therefore, the answer is no.
