Consider the following premises. If it is sunny, then Robert is running. James is making tea or it is cloudy. If Robert goes running, then it is sunny. If it is late, then Robert is not running. If James makes tea, then Robert is running. If it is cloudy, then it is sunny. Can we infer the following from them? It is late.
 From the fact that if it is sunny, then Robert is running, and that if Robert goes running, then it is sunny we can infer that it is sunny if and only if Robert is running. From the fact that it is sunny if and only if Robert is running we can infer that if it is sunny, then Robert is running. From the fact that if it is cloudy, then it is sunny, and that if it is sunny, then Robert is running we can infer that if it is cloudy, then Robert is running. From the fact that if James makes tea, then Robert is running, that if it is cloudy, then Robert is running, and that James is making tea or it is cloudy we can infer that Robert is running. Finally, from the fact that if it is late, then Robert is not running, and that Robert is running we can infer that it is not late, which contradicts that It is late. Therefore, the answer is no.
