Consider the following premises. Thomas is making tea if and only if Thomas is cooking. Thomas is not making tea. For all x, if x makes tea, then x is cooking. Can we infer the following from them? Thomas is cooking.
 From the fact that for all x, if x makes tea, then x is cooking we can infer that if Thomas makes tea, then Thomas is cooking. From the fact that Thomas is making tea if and only if Thomas is cooking we can infer that if Thomas cooks, then Thomas is making tea. From the fact that if Thomas makes tea, then Thomas is cooking, and that if Thomas cooks, then Thomas is making tea we can infer that Thomas is making tea if and only if Thomas is cooking.
