Mr. Green - for non-organic food
Mr. Jakes -  for -organic food

Mr. Green: Mr. Jakes, do you know that most of the world's population consumes non organic food?
Mr. Jakes: I don`t agree with you, Mr. Green. Organic foods are preferred by people who are more conscious about their health.
Mr. Green: Maximum consumers buy non organic food, as it is cheaper and easily available. Why should we eat organic food?
Mr. Jakes: Organic foods are safer and better, as they don't use any toxic chemicals in comparison with non-organic food. I know many times harmful preservatives are added to non-organic foods.
Mr. Green: They are not harmful. Non organic food is treated with preservatives in order to have a good shape and colour. And I also want to emphasize, Mr. Jakes, that organic food is more expensive than non-organic one.
Mr. Jakes: Organic foods contain more nutrients, that is, a higher amount of minerals and vitamins. Taste differs between organic and non-organic food, but this is debatable, as taste is a factor which varies, from individual to individual.

Michael Faraday is one of the great scientists in the history of man's work in electricity. He was born in a small village near London on September 11, 1791, in a poor family. His family lived from hand to mouth. At the age of thirteen Michael went to work in a bookbinder's shop, because he didn't have much schooling. Some of the scientific works and articles which passed through his hands aroused his interest in science and he started to read. Some time later Michael became a pupil of great scientist of that time, Sir Humphry Davy. The boy accompanied Davy in his trips to Europe. The educational value of such trips Was great. Among great men of science Faraday met Ampere, who had already made a name for himself in the history of electricity.
Майкл Фарадей - один из великих ученых в истории человечества в области электричества. Он родился в ма­ленькой деревне вблизи Лондона 11 сентября 1 791 года в бедной семье. Его семья жила впроголодь. В возрасте 13 лет Майкл пошел работать в переплетный магазин, пото­му что не получил образования. Некоторые научные рабо­ты и статьи, которые через его руки, возбудили интерес к науке, и он начал читать. Спустя некоторое время Майкл стал учеником велико­го ученого того времени, сэра Хамфри Дэйви. Мальчик со­провождал Дэйви в поездках по Европе. Образовательная ценность этих поездок была велика. Фарадей встретил Ампера, одного из выдающихся ученых, который уже сде­лал себе имя в истории электричества.
Today almost all the electricity we use generated by great machines with magnets in them, but in those days no one knew how to it. That's why the English scientist danced with delight on his table when he got what he wanted by moving the magnet near wire. This was a great moment in the history of man's electrical experiments. But Faraday didn't stop at this.
