In a certain rural area, people normally dispose of household garbage by burning it. Burning household garbage releases toxic chemicals known as dioxins. New conservation regulations will require a major reduction in packaging—specifically, paper and cardboard packaging—for products sold in the area. Since such packaging materials contain dioxins, one result of the implementation of the new regulations will surely be a reduction in dioxin pollution in the area.
Which of the following, if true, most seriously weakens the argument?
Garbage containing large quantities of paper and cardboard can easily burn hot enough for some portion of the dioxins that it contains to be destroyed.
Packaging materials typically make up only a small proportion of the weight of household garbage, but a relatively large proportion of its volume.
Per-capita sales of products sold in paper and cardboard packaging are lower in rural areas than in urban areas.
The new conservation regulations were motivated by a need to cut down on the consumption of paper products in order to bring the harvesting of timber into a healthier balance with its regrowth.
It is not known whether the dioxins released by the burning of household garbage have been the cause of any serious health problems.
P package含有D
C 减少package能够减少D
A:垃圾燃烧产生D,package包含D,package减少,D减少;但是A指出燃烧垃圾时,其中有大量的package,释放的热量能够破坏D的蛋白质,减少D
所以减少了package并不一定能够达成减少D的目标,即削弱
蛋白质是protein 看错了吧兄弟
