Article: In Western countries people have been using the installment plan since the first half of the twentieth century. Today, a large number of families in Great Britain buy furniture, household goods and cars by installments .In the U.S., the figure is much higher than in Great Britain, and people there spend over 10 percent of their income on the installment plan. The price of an article bought on installments is always higher than the price that would be paid by cash. There is a charge for interest. The buyers pays one quarter or one third of the price as a down payment when the goods are delivered to him. He then makes regular payments, weekly or monthly, until the full price is paid up. The legal ownership of the goods remains with the seller until the final payment has been made. Installment buying has advantages and disadvantages. It can help couples with small incomes to furnish their homes and start housekeeping, It increases the demand for goods, and in this way helps business and employment. There is ,however, the danger that when business is bad, installment buying may end suddenly, making business much worse. This may result in a great increase in unemployment. If the people on the installment plan lose their jobs, they will probably not be able to make their payments. If great numbers of people are not able to pay their installment debts there is a possibility that businessmen cannot collect their debts and will therefore lose money. If businessmen lose money or fail to make a satisfactory profit, it becomes more likely to have a depression. This is why, in some countries, the government controls the installment plan by fixing the amount of the down payment to discourage people from buying more than they can pay for on the installment plan.
Answer: The payment of installment buying is easier than buying by cash.
answer:
Which of the following is true about the installment plan?

Article: Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. "It's a _ ," said lead researcher Frank Stafford at University of Michigan's Institute for Social Research. "Men usually work more outside the home, while women take on more of the housework." He points out that differences among households exist. But in general, marriage means more housework for women and less for men. "And the situation gets worse for women when they have children." Stafford said. Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005. Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most - about 21 hours a week. Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men. Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands' 10 hours.

Article: We use an average of 158 liters of water a day in Britain, for which we pay a bargain price of 28p a liter, but much of this is just cash down the drain, according to water companies. Most are campaigning to cut the amount we use. And the frontline weapon in their campaign is the water meter . They want us all to have one and one company is seeking powers to make this compulsory. The Government is anxious for us to use less water, too. Elliot Morley, the Environment Minister, says he is impressed by the savings when a meter is installed. In most homes, consumption drops by 20 percent. He also thinks consumers get a good deal from meters. He said, "Most people would find that they would either be exactly the same or better off with water meters and it is a fairer way of paying for water." At present, only 25% of households have meters and most of those are in East Anglia. They are installed by water companies, and households then have about PS43 added to each bill to cover the cost of installing and reading the meter. Barrie Clarke, a spokesman for Water UK, said, "We want everyone to be more water wise--to think about the amount of water they use. But with our climate change and different weather patterns, over time it will make economic and environmental sense to think how we use water. This may mean meters." Mr. Clarke believes the easiest way to save water is to use less in the garden. In one hour, a sprinkler uses the same amount of water as the average family of four uses in a day--about 632 liters. He said that gardeners should water in the evening so that it dose not _ in the heat of the day and that every household should have a water butt to collect rainwater for use in the garden.
