Consider the following premises. If Sarah drives a car, then it is sunny. Sarah is driving a car or Richard is making tea. If Richard makes tea, then it is sunny. For all z, z will take a plane. Can we infer the following from them? It is not sunny.
 From the fact that for all z, z will take a plane we can infer that David is taking a plane. Finally, from the fact that if Sarah drives a car, then it is sunny, that if Richard makes tea, then it is sunny, and that Sarah is driving a car or Richard is making tea we can infer that it is sunny, which contradicts that It is not sunny. Therefore, the answer is no.
