Consider the following premises. If it is overcast, then James is taking a plane. If James takes a plane, then it is cold. If it is cold, then Sarah is a taxi driver. If Sarah were a taxi driver, then it is cold. Can we infer the following from them? The fact that it is overcast does not imply that Sarah is a taxi driver.
 From the fact that if it is cold, then Sarah is a taxi driver, and that if Sarah were a taxi driver, then it is cold we can infer that it is cold if and only if Sarah is a taxi driver. From the fact that if it is overcast, then James is taking a plane, and that if James takes a plane, then it is cold we can infer that if it is overcast, then it is cold. From the fact that it is cold if and only if Sarah is a taxi driver we can infer that if it is cold, then Sarah is a taxi driver. Finally, from the fact that if it is overcast, then it is cold, and that if it is cold, then Sarah is a taxi driver we can infer that if it is overcast, then Sarah is a taxi driver, which contradicts that The fact that it is overcast does not imply that Sarah is a taxi driver. Therefore, the answer is no.
