问题     Here is a great irony of 21st century global health: while many hundreds of millions of people lack adequate food as a result of economic inequities, political corruption, or warfare, many hundreds of millions more are overweight to the point of increased risk of diet-related chronic diseases. Obesity is a worldwide phenomenon, affecting children as well as adults and forcing all but the poorest countries to divert scarce resources away from food security to take care of people with preventable heart disease and diabetes.
    To reverse the obesity epidemic, we must address the fundamental cause. Overweight comes from consuming more food energy than is expended in activity. The cause of this imbalance also is ironically improved prosperity. People use extra income to eat more and be less physically active. Market economies encourage this. They turn people with expendable income into consumers of aggressively marketed foods that are high in energy but low in nutritional value, and of cars, television sets, and computers that promote sedentary behavior. Gaining weight is good business. Food is particularly big business because everyone eats.
    Moreover, food is so overproduced that many countries especially the rich ones, have far more than they need — another irony. In the United States, to take an extreme example, most adults — of all ages, incomes, educational levels, and census categories — are overweight. The U. S. food supply provides 3800 kilocalories per person per day, nearly twice as much as required by many adults. Overabundant food forces companies to compete for sales through advertising, health claims, new products, larger portions, and campaigns directed towards children. Food marketing promotes weight gain. Indeed, it is difficult to think of any major industry that might benefit if people eat less food; certainly not the agriculture, food product, grocery, restaurant, diet, or drug industries. All flourish when people eat more, and all employ armies of lobbyists to discourage governments from doing anything to inhibit overeating.
Which of the following can be excluded as we can understand based on the passage?
选项 A、The economic dimension.
B、The political dimension.
C、The humane dimension.
D、The dietary dimension.
答案C
解析 推断题。本题题意是：“根据本段文字我们所理解的，哪个可以排除掉?”文中谈到肥胖的原因显然有A经济层面的原因；最后一段最后一句话告诉我们，没有商家会雇用说客说服政府放弃限制吃得过多的举措，所以说也有B项政治层面的因素；D项饮食层面的显然是导致肥胖的直接因素。所以只能选C，人道层面。
