The following dialog is for questions 11 to 13.

Yayan: Have you had lunch?

Diah: No, I haven't.

Yayan: Then, let's go to the school canteen. I heard that today they cook beef rendang.

Diah: Really? Rendang is my favorite. It is so delicious.

Yayan: No wonder, it becomes one of the most delicious food in the world. Do you know where does it come from?

Diah: Yes, it comes from Padang West Sumatra, right?

Yayan: You're right. Anyway, can you cook rendang?

Diah: Yes, I can. My mom taught me how to cook it. There are two different types of rendang, the dried and moist one. Dried
rendang can be stored up to three or four weeks at room temperature, but it should be cooked for longer hours than the moist
rendang, to make the herbs and spices completely absorbed by the beef.

Yayan: Wow, you have good knowledge off rendang.Your cooking must be delicious.

Diah: Not really, but my mother's rendang is the best. You should come to my house and taste it someday.

Yayan: Sure, I'd love to.
