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.

(E) Sometimes, in packaging an item, plastics that are not biodegradable in landfills are combined with cardboard.

答案是A，我觉得A与B基本没有区别，如果非说有些不同，那应该是在范畴上，一个是usually，一个是some，大家是这样理解而得出答案的吗？ 我倒觉得B更好，因为plastic是biodegradable，这样替换之后不会变得更差，否则即使一些paper and cardboard不是bidegradable， 替换成plastic后，也不一定会变得更好，岂不是多此一举！

Which of the following, if true, is the most logical completion of the argument below?

The tax system of the Republic of Grootland encourages borrowing by granting its taxpayers tax relief for interest paid on loans. The system also discourages saving by taxing any interest earned on savings. Nevertheless, it is clear that Grootland’s tax system does not consistently favor borrowing over saving, for if it did, there would be no______

(A) tax relief in Grootland for those portions of a taxpayer’s income, if any, that are set aside to increase that taxpayer’s total savings

(B) tax relief in Grootland for the processing fees that taxpayers pay to lending institutions when obtaining certain kinds of loans

(C) tax relief in Grootland for interest that taxpayers are charged on the unpaid balance in credit card accounts

(D) taxes due in Grootland on the cash value of gifts received by taxpayers from banks trying to encourage people to open savings accounts

(E) taxes due in Grootland on the amount that a taxpayer has invested in interest-bearing savings accounts

答案是A,恕我捉劣，没读明白题要说明什么经济道理。

1。原文推理中最大的问题在于：不知道paper and cardbord 生物可降解性怎样。不知道这信息就无法下结论。B严格讲是OUT OF SCOPE。因为原文结论是用不能降解的塑料去替代。跟能降解的塑料无关。

2。原文意思：某地方通过减少借款利息的税收这种方式去鼓励借款，用存款利息征税的方式压制存款。但是，该地方实际是税收系统一贯支持存款多与支持借款。因为如果不是这样（即如果支持借款多），则。。。（答案应该是支持BORROWING多点，支持SAVING少点）。

又是双重否定，又是虚拟语气。太绕。很容易将人套进去。B正好相反。B是少支持BORROWING（BORROWING处理费应该无减免税）。A是少支持SAVING（拿去存款的那部分收入应该无减免税）。答案要少支持SAVING，即A。

求教2。

仍然不太明白A后面半句的意思。从然而开始似乎是说“很明显，税收系统并不总是支持借款多过存款（即支持存款大于或等于借款），否则（即支持借款多过存款）就不会有纳税人收入部分的税收减免”，if any后面不确定是不是说“如果有（收入税收减免），那是用来增加纳税人的总存款的。”

请问 it is always a change for the worse to

change for the worse

什么意思啊？？哈哈
