Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.
As working women continue to receive better and better wages, housewives still work at home without receiving pay- checks. Should a woman who works at home, doing the housework and caring for children, be paid for her services? In a 1986 study at Cornell University, sociologists found that the value of the services of a housewife averaged 11,600 USD a year. "This rate was based on a family composed of a husband, wife and three young children. The 11,600 USD is what the husband would have to pay if he hire others to take over his wife's household chores. The researchers concluded that it would be fair for husbands to pay wives according to federal guidelines for minimum wages.
Another plan for rewarding women who work at home has been suggested by a former Secretary of Health and Human Services. He says that full-time housewives should be allowed to pay social security taxes, with their employers contributing part of payment. He feels that the present system is unfair. He said, “If you work as a clerk in a store, you can qualify for social security, but if you stay at home and raise a family, nobody will give you credit for it.”
