Consider the following premises. If Richard were an astronaut, then it is windy. It is not windy. If Michael were bored, then Richard is an astronaut. Michael is running if and only if Michael is bored. Can we infer the following from them? Michael is running.
 From the fact that if Michael were bored, then Richard is an astronaut, and that if Richard were an astronaut, then it is windy we can infer that if Michael were bored, then it is windy. From the fact that Michael is running if and only if Michael is bored we can infer that if Michael goes running, then Michael is bored. From the fact that if Michael goes running, then Michael is bored, and that if Michael were bored, then it is windy we can infer that if Michael goes running, then it is windy. Finally, from the fact that if Michael goes running, then it is windy, and that it is not windy we can infer that Michael is not running, which contradicts that Michael is running. Therefore, the answer is no.
