Questions 71 -80 are based on the following passage.
　　The field of medicine has always attracted its share of quacks and charlatans —disreputable women and men with little or no medical knowledge who promise quick cures at cheap prices. The reasons why quackery thrives even in modern times are easy to find.
　　To begin with, pain seems to be a chronic human condition. A person whose body or mind “hurts” will often pay any amount of money for the promise of relief. Second, even the best medical treatment cannot cure all the ills that beset men and women.People who mistrust or dislike the truths that their physicians tell them often turn to more sympathetic ears.
　　Many people lack the training necessary to evaluate medical claims. Given the choice between (a) a reputable physician who says a cure for cancer will be long,expensive and may not work at all, and (b) a salesperson who says that several bottles of a secret formula “snake oil” will cure not only cancer but tuberculosis as well,some individuals will opt for “snake oil”.
　　Many “snake oil” remedies are highly laced with alcohol or narcotic drugs.
　　Anyone who drinks them may get so drunk or stoned that they drown their pains in the rising tide of pleasant intoxication. Little wonder that “snake oil” is a popular cure-all for minor aches and hurts! But let there be no misunderstandings. A very few “home remedies” actually work. However, most remedies sold by quacks are not only useless, but often can be harmful as well.

　　Questions 81 -90 are based on the following passage.
　　Modern industrial society grants little status to old people. In fact, such a society has a system of built-in obsolescence. There is no formal system for continuing our education throughout our life in order to keep up with rapidly changing knowledge.
　　When our education and job skills have grown obsolete, we are treated exactly like those who have never gained an education or job skills and are not encouraged or given the opportunity to begin anew.
　　As a society becomes more highly developed, the overall status of older people diminishes. Improved health technology creates a large pool of old people, who compete for jobs with the young. However, economic technology lowers the demand for workers and creates new jobs for which the skills of the aged are obsolete, forcing older people into retirement. At the same time, young people are being educated in the new technology and are keeping pace with rapid changes in knowledge. Finally,urbanization creates age-segregated neighborhoods. Because the old live on fixed incomes, they must often live in inferior housing. All these factors — retirement, obsolete knowledge and skills, inferior standards of living — lower the status of the aged in society.
　　A century ago, when one could expect to live only to 50 or so, the life span more or less coincided with the occupation and family cycle. But today the average life span allows for fifteen to twenty years of life after these cycles. It appears that our life span is outpacing our usefulness in society.
