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.
答案是C。。为什么呢。牛牛看看我推的逻辑链有木有错。discard less food -->the more standardized--->the greater the quantities of fresh如果是这样的话。。那明明逆否命题才是正确的。可是C只是the more standardized--->the greater the quantities of fresh的否命题。怎么会是正确的呢？？求助求助！！谢谢大牛拉
A、"increasing number of household" is irrelevant. B、"nonfood waste" is irrelevant. C、"standardized","fresh produce" and "food waste" are mentioned in the passage, keep this answer. D、"standardized" equal "canned and prepackaged foods", so D) should be wrong. E、"buy" is irrelevant.
