8. 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.（C）
(E) The more fresh produce a household buys, the more fresh produce it throws away.跳起脚，up,up.

Which of the following can be properly inferred from the passage?
your analysis of "由A-->B推出－A-->－B" is correct, that is the reason why C is the answer.
E is wrong because it is the opposite of the argument.
I have to clarify that "由A-->B推出－A-->－B" here is not the 逆否命题
that we usually mean, it is simply a math problem. The more...,the more..., by the same token, the less..., the less....
Please pay attention to the word "proportion".
