问题     Modern mass-production methods lower the cost of making goods, and thus give us better values. At the same time, American ingenuity (独创性) and science are constantly at work improving the quality of products. In this way, better quality products at good values are continually being brought to the people of all income groups.
    As an example of how this worked, when facial tissues (面巾纸) were first put on the market in 1924, they were made in limited quantities and sold at 65 cents per box of 200. People like these facial tissues immediately and began asking for them when they went into different stores. Because there was such a demand for the product, manufacturers began making tissues in larger and larger quantities’. Because the manufacturers were making tissues in greater quantities, their production costs were lowered, so that the price of tissues went down. In the meanwhile, the quality of facial tissues was constantly improving, because more manufacturers went into the business of making tissues, and each manufacturer strove to make his product better than his competitors’. Today, instead of costing 65 cents, a box of 200 tissues costs around one-third of that price, and they are both softer and stronger.
    When people are free to compete—when they are free to make more things and make them better—everyone benefits.
Improved quality of facial tissues resulted from______.
选项 A、mass-production methods
B、popular demand for a better product
C、a decrease in production costs
D、competition among manufacturers
答案D
解析 本题考查考生对文章细节的把握。文章第一段可知mass—production“批量生产”的结果是价格和成本的下降，与产品质量无关，排除A项。根据第二段面巾纸的例子，当需求增加时，厂家会加大生产量，并有更多厂商投入生产，并提及质量，因此排除B。而C项产品成本下降，并不能直接导致质量上升，排除C项，根据第二段划线部分句子可知，厂商为使自己的产品比竞争对手好，会努力提高质量，因此选D项。
