For all x_11, if x_11 takes a plane, then x_11 is an electrician. For all x_11, x_11 will make tea or x_11 is not an electrician. For all x_11, if x_11 makes tea, then x_11 is taking a plane. For all x_11, x_11 will work if and only if x_11 will take a plane. For all x_11, x_11 will not work.
For all x_11, if x_11 makes tea, then x_11 is an electrician. For all x_11, if x_11 were an electrician, then x_11 is making tea. For all x_11, if x_11 works, then x_11 is taking a plane. For all x_11, if x_11 takes a plane, then x_11 is working. For all x_11, x_11 will not take a plane.
