Questions 51 to 55 are based on the following passage. You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway. Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workplace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry. The average international runway model has a body mass index (BMI) under 16--low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence. "Especially girls and teens," says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines. "That's especially worrying, she says, given that anorexia (厌食症) results in more deaths than does any other mental illness, according to the National Institute of Mental Health. It's commonly known that certain diseases are linked with occupations like lung disease in coalminers. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness. Record's suggestion is to prohibit agents from hiring models with a BMI below 18. In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with a BMI under 18 could pay $ 82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week. "
