Consider the following premises. If it snows, then Robert is an artist. If Thomas were an electrician, then it is snowing. If Linda sleeps, then John is drinking water. If Robert were an artist, then Linda is sleeping. If John drinks water, then Thomas is an electrician. Can we infer the following from them? The fact that Robert were an artist does not imply that Thomas is an electrician.
 From the fact that if Robert were an artist, then Linda is sleeping, and that if Linda sleeps, then John is drinking water we can infer that if Robert were an artist, then John is drinking water. Finally, from the fact that if Robert were an artist, then John is drinking water, and that if John drinks water, then Thomas is an electrician we can infer that if Robert were an artist, then Thomas is an electrician, which contradicts that The fact that Robert were an artist does not imply that Thomas is an electrician. Therefore, the answer is no.
