Name the inference rule being used: If it is sunny, then Robert is bored. If it is cold, then it is sunny. If it is late, then William is running. If William goes running, then Robert is bored. If Robert were bored, then it is late.
If it is sunny, then it is late can be inferred via the transitivity rule. If it is cold, then Robert is bored can be inferred via the transitivity rule. If it is late, then Robert is bored can be inferred via the transitivity rule. If William goes running, then it is late can be inferred via the transitivity rule. If Robert were bored, then William is running can be inferred via the transitivity rule.
