Задание № 1.
1. Translate the text into Russian and put all kinds of questions to the underlined sentence.
Elasticity Of Demand
The shape and slope of demand curves for different products are often quite different. If, for example, the price of a quart of milk were to triple, from $.80 to $2.40 a quart, people would buy less milk. Similarly, if the price of all cola drinks were to jump from $1 to $3 a quart (an identical percent increase), people would buy less cola. But even though both prices changed by the same percentage, the decrease in milk sales would probably be far less than the decrease in cola sales.
This is because people can do without cola more easily than they can do without milk. The quantity of milk purchased is less sensitive to changes in price than is the quantity of cola. Economists would explain this by saying that the demand for cola is more elastic than the demand for milk. Elasticity describes how much a change in price affects the quantity demanded.
