Name the inference rule being used: If Robert plays a game, then it is cold. Robert is playing a game or Robert is not drinking water. If it is cold, then Robert is drinking water.
If Robert plays a game, then Robert is drinking water can be inferred via the transitivity rule. If Robert drinks water, then Robert is playing a game can be inferred via the rewriting rule.
