1.A need is something you have to have to survive or complete a task. A want is simply the desire for something, in many cases something to satisfy a need. You need food to survive.
2.In the field of behavioral economics, the term utility refers to the perceived value (i.e., usefulness) an individual receives when they purchase a good or service. There are four different types of utility: form, place, time, and possession utility.
3.We must help to anybody who fell in bad trouble to do our society better/
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.

like New Year's Day, it is my favourite holiday.
Our family prepares for this holiday beforehand. My father buys and brings home a beautiful New Year's tree at the end of December. Our family has a tradition to buy it. I like to decorate the New Year's tree with toys, little coloured lights, sweets and a beautiful star on the top. My mother and grandmother prepare our holiday supper and lay the table. All the members of our family clean the flat before this nice holiday and then each of us try to dress well.
We like to see the New Year in at home with our relatives. They come to see us at 11 o'clock in the evening. At 12 o'clock we are sitting at the table and we are glad to see the New Year in. We say, "Best wishes for the New Year!". I hope that next year will be better than the last one. The
New Year's Day is always connected with our new hopes and dreams. It is a pleasant moment to get presents on the New Year's Eve. I usually get many nice useful things from my parents and relatives. My parents put their presents under the New Year's tree. We don't go to bed till morning, we watch TV, dance, eat tasty things and make jokes. I enjoy this holiday very much.
