Consider the following premises. For all x_12, if x_12 were a poet, then x_12 is sleeping. For all x_12, x_12 will drive a car if and only if x_12 will sleep. There is at least one x_12 for which x_12 is a poet or x_12 will drive a car. Can we infer the following from them? There is at least one x_12 for which x_12 will sleep or x_12 will make tea.
 From the fact that for all x_12, x_12 will drive a car if and only if x_12 will sleep we can infer that for all x_12, if x_12 drives a car, then x_12 is sleeping. From the fact that for all x_12, if x_12 were a poet, then x_12 is sleeping, that for all x_12, if x_12 drives a car, then x_12 is sleeping, and that there is at least one x_12 for which x_12 is a poet or x_12 will drive a car we can infer that there is at least one x_12 for which x_12 will sleep. Finally, from the fact that there is at least one x_12 for which x_12 will sleep we can infer that there is at least one x_12 for which x_12 will sleep or x_12 will make tea. Therefore, the answer is yes.
