Consider the following premises. For all x_8, if x_8 listens to a song, then x_8 is a taxi driver. For all x_8, x_8 is an electrician or x_8 will listen to a song. There is at least one x_8 for which x_8 is an electrician if and only if x_8 will make tea. For all x_8, if x_8 were a taxi driver, then x_8 is making tea. Can we infer the following from them? For all x_8, x_8 will not make tea.
 From the fact that there is at least one x_8 for which x_8 is an electrician if and only if x_8 will make tea we can infer that there is at least one x_8 for which if x_8 were an electrician, then x_8 is making tea. From the fact that for all x_8, if x_8 listens to a song, then x_8 is a taxi driver, and that for all x_8, if x_8 were a taxi driver, then x_8 is making tea we can infer that for all x_8, if x_8 listens to a song, then x_8 is making tea. Finally, from the fact that there is at least one x_8 for which if x_8 were an electrician, then x_8 is making tea, that for all x_8, if x_8 listens to a song, then x_8 is making tea, and that for all x_8, x_8 is an electrician or x_8 will listen to a song we can infer that there is at least one x_8 for which x_8 will make tea, which contradicts that For all x_8, x_8 will not make tea. Therefore, the answer is no.
