Radio interviewer: Saleem and Tareq? I’m going to give you some clues about a precious stone. You guess the correct precious stone from my description. Are you ready?
Saleem and Tareq: Yes, we are!
Radio Interviewer: These precious stones are some of the hardest stones on Earth. Some are millions of years old. They come from many different continents, but no one has found them in Europe.
Saleem: It might be ruby because it is a hard precious stone.
Tareq: It can’t be amber because amber is found in northern Europe.
Saleem: I know! It must be diamond!
Radio Interviewer: Yes, you’re right. Well done! Now, this precious stone is red. It can sell for higher prices than diamond.
Tareq: This one must be ruby. Rubies are red.
Saleem: Yes, it can’t be emerald because emeralds are green.
Radio interviewer: Yes, you’re right! Now, this one is precious, but it isn’t a stone. It grows in the shell of an oyster. It has many colours: white, yellow, pink, blue and even black.
Saleem: It could be amber. Amber has many different colours.
Tareq: No, it can’t be amber because amber doesn’t grow in the shell of an oyster. I think it must be pearl.
Radio interviewer: Yes, well done Tareq! It is pearl. This last precious stone is usually green, but it can also be pale blue. Today, it usually comes from Colombia in South America.
Saleem: This must be emerald. Emeralds are blue and green.
Radio interviewer: Yes, you’re right. Well done, boys!
