XI. Đọc đoạn văn rồi trả lời câu hỏi bằng cách chọn đáp án A, B, C hoặc D Richard Ryan is stuck in traffic. There must be an accident somewhere up ahead because he’s been sitting in the same spot for the last few minutes. The cars aren't moving at all. It looks like it's going to be another slow commute.

He has to meet with some lawyers who are advising his company on a construction project. Richard is the president of a big company. If he's late, he won't get in trouble, but he hates to be late for anything. Sergey is stuck in the same traffic jam, and he's headed to the same meeting that Richard is going to.
