151. Benton City residents have adopted healthier lifestyles. A recent survey of city residents shows that the eating habits of city residents conform more closely to government nutritional recommendations than they did ten years ago. During those ten years, local sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol, have increased fourfold, while sales of sulia, a food rarely eaten by the healthiest residents, have declined dramatically. Because of these positive changes in the eating habits of Benton City residents, we predict that the obesity rate in the city will soon be well below the national average.
Benton City的居选择了更健康的生活方式。他们对于最近一项调查的回答显示，他们的饮食习惯比十年前更加贴近政府的营养建议。而且，含有kiran的食品销量增长了四倍，在一次科学研究中发现kiran是一种能够降低胆固醇水平的物质。而sulia—一中最健康的居民家少食用的视频的销量下降了。由于Benton City居民饮食习惯发生的积极的变化，我们预计该市的肥胖率将会很快下降到全国平均水平值以下。

152. The following appeared in a memo to the board of directors of Bargain Brand Cereals.
"One year ago we introduced our first product, Bargain Brand breakfast cereal. Our very low prices quickly drew many customers away from the top-selling cereal companies. Although the companies producing the top brands have since tried to compete with us by lowering their prices and although several plan to introduce their own budget brands, not once have we needed to raise our prices to continue making a profit. Given our success in selling cereal, we recommend that Bargain Brand now expand its business and begin marketing other low-priced food products as quickly as possible."
下面这段文字出自Bargain Brand Cereals董事会的备忘录。
一年以前我们推出了第一种产品Bargain Brand早餐麦片。我们低廉的价格迅速从一些销量最大的麦片厂商那里吸引了大量客户。尽管这些厂商曾经试图通过降低价格来与我们竞争，并且尽管有一些公司打算推出他们自己的廉价品牌，但我们从未需要通过涨价来持续盈利。基于我们销售麦片的成功经验，Bargain Brand应该扩展业务，并且尽快开始推出其他的廉价食品。
