Mrs. Ana: Excuse me, Sir. Could you tell me how to get to Sahabat Trade Centre from here?

Mr. Johan: It's on Eleventh Street, just across from the police office.

Mrs. Ana: On Eleventh Street?

Mr. Johan: That's right. You know where that is?

Mrs. Ana: I'm afraid I don't know it. As you know that I'm a new comer in this lovely town.

Mr. Johan: Oh, I see. Well, do you know where the old building is?

Mrs. Ana: No, I don't know exactly.

Mr. Johan: I'm not sure going to help you. Let me see.... Why don't you follow this street, Ahmad Yani Street, until you get to the stoplight? Take a right there, that's Adi Sucipto Street, and go up about two or three blocks, until you get Eleventh. Then turn left. The Sahabat Trade Centre is on your right about three blocks down.

Mrs. Ana: Let me get this straight... Go up to Adi Sucito Street, take a right, go three blocks....

Mr. Johan: That's right, two or three.

Mrs. Ana: Then, turn left on Eleventh, and The Sahabat Trade Centre is on the right-hand side, three blocks down.

Mr. Johan: That's right.

In what street is the stoplight located?
