In most parts of the United States, Friday night is the big supermarket night, probably because Friday is payday in many factories and businesses. Most housewives also do their weekend shopping on either Friday or Saturday, although supermarkets in many places are now open on Sunday as well.In almost all supermarkets there are shopping carts with a special space to set the baby. In the early days, before there were carts, it was noticed that as soon as a woman shopper had her arms full of goods, she stopped buying. Thus carts were introduced. Later a space for the baby was provided in the cart. With the baby sitting comfortably in the cart, the mother felt less need to hurry through the store and she would probably buy more. It is said that the average American housewife goes to the supermarket twice a week. On average she will spend from one hour to two hours there each week. Why did the supermarkets provide carts for their customers().

A. Because they wanted their customers to buy more.
Because no one would help the customers to carry their goods.
C. Because babies cried a lot without the carts.
