Read the following paragraph and answer the questions that follow: [6]Americans are probably the most pain-conscious people on the face of the earth. For years we have had it drummed into us—in print, on radio, over television, in everyday conversation—that any hint of pain is to be banished as though it were the ultimate evil. As a result, we are becoming a nation of pill-grabbers and hypochondriacs, escalating the slightest ache into a searing ordeal. We know very little about pain, and what we don’t know makes it hurt all the more. Indeed, no form of illiteracy in the United States is so widespread or costly as ignorance about pain—what it is, what causes it, how to deal with it without panic.Almost everyone can rattle off the names of at least a dozen drugs that can deaden pain from every conceivable cause—all the way from headaches to hemorrhoids. There is far less knowledge about the fact that about 90 percent of pain is self-limiting, that it is not always an indication of poor health, and that, most frequently, it is the result of tension, stress, worry, idleness, boredom, frustration, suppressed rage, insufficient sleep, overeating, poorly balanced diet, smoking, excessive drinking, inadequate exercise, stale air, or any of the other abuses encountered by the human body in modern society! The most ignored fact of all about pain is that the best way to eliminate it is to eliminate the abuse. Instead, many people reach almost instinctively for painkillers—aspirins, barbiturates, codeines, tranquilizers, sleeping pills, and dozens of other analgesics or desensitizing drugs.(a) What is the main purpose of this passage?
