It is better for the environment if as much of all packaging as possible is made from materials that are biodegradable in landfills. Therefore, it is always a change for the worse to replace packaging made from paper or cardboard with packaging made from plastics that are not biodegradable in landfills.
Which of the following, if true, constitutes the strongest objection to the argument above?
(A) The paper and cardboard used in packaging are usually not biodegradable in landfills.
(B) Some plastic used in packaging is biodegradable in landfills.
(C) In many landfills, a significant proportion of space is taken up by materials other than discarded packaging materials.
(D) It is impossible to avoid entirely the use of packaging materials that are not biodegradable in landfills.(A)
(E) Sometimes, in packaging an item, plastics that are not biodegradable in landfills are combined with cardboard.
请问B为什么不对,A从前面一个方面说,B正好从另一个方面讲,我觉得A和B都是可以的。
谢谢!
我同意A, B都是削弱, 但你要考虑which one is stronger
SOME plastic..... 只是说明存在这种可能, 并不strong
