根据材料内容，选择正确答案。

    Two men are walking in the park. One is Jack, a worker. The other is Henry. Jack is going to a chair. It is next to the street. Henry is after him. Jack finds Henry walking after him. He walks faster(更快), because he wants to get to the chair before Henry. Now Henry begins to run because he also wants to get to the chair first. Then he gets to the chair first and sits down on it. When Jack gets to the chair, he sees Henry sitting on it. He is sorry to show a notice（告示）with the words “Wet Paint”（油漆未干）to Henry. Now Henry knows why Jack is going to the chair.
