Consider the following premises. For all y, y will not make tea. Richard is making tea if and only if it is raining. It is raining or Michael is taking a plane. Can we infer the following from them? Michael is not taking a plane.
 From the fact that for all y, y will not make tea we can infer that Richard is not making tea. From the fact that Richard is making tea if and only if it is raining, and that Richard is not making tea we can infer that it is not raining. Finally, from the fact that it is raining or Michael is taking a plane, and that it is not raining we can infer that Michael is taking a plane, which contradicts that Michael is not taking a plane. Therefore, the answer is no.
