My favorite TV show is Voice. It is a singing competition. There are four coaches. They listen to singers without seeing them, and turn their chairs to signify that they are interested in working with that artist. If more than one coach turns the chair, the artist chooses the coach. IIt is si interesting. The coaches sometimes can't understand if it is a woman or a man singing. Or they think that it is an old man, then turn thier chair and see that it is a young woman. There you can see many talanted people. U think this show is a good chance for talanted people. I like this show very much.

4.We speak with different people from different countries.Many nations want submarines. Economists say that utility determines 'the relationship between a consumer and a commodity'.
Utility varies between different people and between different nations. A vegetarian does not want meat, but may rate the utility of bananas very highly, while a meat-eater may prefer steak. A mountain-republic like Switzerland has little interest in submarines, while maritime nations rate them highly.
5.The production of pianos falls sharply in wartime.
The utility of a commodity is also related to the quantity which is available to the consumer. If paper is freely available, people will not be so interested in buying too much of it. If there is an excess of paper, the relative demand for paper will go down.
