Consider the following premises. If Thomas goes running, then James is fast. James is fast if and only if Susan is drinking water. Richard is playing squash. Thomas is running or Susan is drinking water. Can we infer the following from them? James is not fast.
 From the fact that James is fast if and only if Susan is drinking water we can infer that if Susan drinks water, then James is fast. Finally, from the fact that if Thomas goes running, then James is fast, that if Susan drinks water, then James is fast, and that Thomas is running or Susan is drinking water we can infer that James is fast, which contradicts that James is not fast. Therefore, the answer is no.
