Questions 1 to 5 are based on the following passage. ST. LOUIS—It’s no secret that raising children’ can be expensive, but how about a quarter of a million dollars expensive? A govermnent report released Tuesday said a middle-income family with a child born last year will spend about $221,000 raising that child until the age of 17. The report by the US Department of Agriculture’s Center for Nutrition Policy and Promotion identified housing as the largest single expense, followed by food and child care/education costs. The $221,000 in expenses rises to about $292,000 when adjusted for inflation. USDA economist Mark Lino, who co-authored the report with Andrea Carlson, often hears people say children cost a lot when the annual findings are issued. “I tell them children also have many benefits, so you have to keep that in mind,” he said. Families with more income spend more on child-related costs, the report said. A family that earns less than $57,000 annually will spend about $160,000 on a child from birth until the end of high school. Those with an income between $57,000 and $99,000 spend about $221,000, and those with higher incomes spend roughly $367,000. Costs of raising a child are highest in the urban Northeast and lowest in the urban South and rural areas. The USDA report helps courts and states determine child-support guidelines and foster-care payments. It does not address costs specifically related to childbearing and paying for college. One of the largest changes over time has been the increase in costs related to care for young children. The report first was issued in 1960, when such costs were largely negligible, but with more working families turning to outside help with child care, it has grown to be a significant expense for many families. The report does not give total costs related to early child care. Raben Andrews, a mother of three in St Louis, said the government figures sounded right to her. “Well, that’s not half of it,” the 42-year-old schoolteacher joked. “I still have to put the little devils through college.” Questions 1 to 5 Answer the following questions with the information given in the passage in a maximum of 10 words for each question. 1．What is the average yearly expense for a child in a middle-income American family? 2．What is the largest single cost in raising a child in the USA? 3．Where is the most expensive area to raise a child in the USA? 4．Which cost in raising children has increased the most? 5．According to Raben Andrews, what will cost a large sum of money?
