     As one approaches some crossroads, one comes to a sign which says that drivers have to stop when

they come to the main road ahead. At other crossroads, drivers have to go slow, but they do not actually

have to stop (unless, of course, there is something coming along the main road); and at still others, they do not have either to stop or to go slow, because they are themselves on the main road.

    Mr. Williams, who was always a very careful driver, was driving home from work one evening when

he came to a crossroads. It had a "Slow" sign, so he slowed down when he came to the main road,

looked both ways to see that nothing was coming, and then drove across without stopping completely.

     At once he heard a police whistle, so he pulled in to the side of the road and stopped. A policeman

walked over to him with a notebook and pencil in his hand and said, "You didn't stop at the crossing."

"But the sign there doesn't say "Stop"," answered Mr. Williams. "It just says "Slow", and I did go slow."  

The policeman looked around him, and a look of surprise came over his face. Then he put his notebook

and pencil away, scratched his head and said, "Well, I'll be scolded. I am in the wrong street!"        

1. Which of the following statements is correct? ?

A. Stop signs can be found at every crossroads.

B. At crossroads with a "Slow" sign, drivers never have to stop.

C. At crossroads with a "Slow" sign, drivers have to stop and then go slow.

D. At some crossroads, drivers needn't stop or go slow.

2. What do you think the policeman would do in the end?

A. Fine Mr. Williams.                    

B. Take him to the police station.

C. Apologize to Mr. Williams.            

D. Give Mr. Williams his notebook and pencil.

3. Which might be the best title for this passage?

A. Signs at the crossroads              

B. A careful driver

D. Policeman in the wrong street
