53.By analyzing the garbage of a large number of average-sized households, a group of modern urban anthropologists has found that a household discards less food the more standardized—made up of canned and prepackaged foods—its diet is. The more standardized a household’s diet is, however, the greater the quantities of fresh produce the household throws away. Which of the following can be properly inferred from the passage? (A) An increasing number of households rely on a highly standardized diet. (B) The less standardized a household’s diet is, the more nonfood waste the household discards. (C) The less standardized a household’s diet is, the smaller is the proportion of fresh produce in the household’s food waste. (D) The less standardized a household’s diet is, the more canned and prepackaged foods the household discards as waste. (E) The more fresh produce a household buys, the more fresh produce it throws away. The answer is C. the less food waste -> the more standardized 是这样的吗,然后用逆否命题得到C? Statements: the greater the quantities of fresh produce the household throws away这不是在说绝对数量吗?可是C在说 proportion. quantity和proportion 不是不对等的两个概念吗? 还有D选项有些迷惑。 请各位帮助。 |
