The recycling of municipal solid waste is widely seen as an environmentally preferable alternative to the prevailing practices of incineration and of dumping in landfills. Recycling is profitable, as the recycling programs already in operation demonstrate. A state legislator proposes that communities should therefore be required to adopt recycling and to reach the target of recycling 50 percent of all solid waste within 5 years.
Which of the following, if true, most seriously calls into question the advisability of implementing the proposal?
选项
A、Existing recycling programs have been voluntary, with citizen participation ranging from 30 percent in some communities to 80 percent in others.
B、Existing recycling programs have been restricted to that 20 percent of solid waste that, when reprocessed, can match processed raw materials in quality and price.
C、Existing recycling programs have had recurrent difficulties finding purchasers for their materials, usually because of quantities too small to permit cost-effective pickup and transportation.
D、Some of the materials that can be recycled are the very materials that, when incinerated, produce the least pollution.
E、Many of the materials that cannot be recycled are also difficult to incinerate.
答案
B
解析
To answer this question, consider what information would call the advisability of implementing this proposal into question.
A state legislator proposes that communities be required to target recycling 50 percent of all solid waste within five years. This legislator argues for the plan in part on the basis that recycling programs already in operation are profitable.
To weaken this argument, consider whether there might be a reason that significantly changing the
amount or types of solid waste currently disposed of would make currently profitable recycling programs unprofitable.
A This does not cast much doubt on the advisability of implementing the plan. If some communities manage to get as many as 80 percent of their citizens to participate, the goal of recycling 50 percent of all solid waste within certain communities seems attainable.
B Correct. This suggests that increasing the percentage of solid waste that is recycled to 50 percent may result in a significant amount of recycled, reprocessed material of inferior quality. If this material cannot match processed materials in quality and price, this may make recycling programs no longer profitable.
C If the problem is a result of the small quantities, increasing the quantities of materials could alleviate the problem. Therefore, this does not cast doubt on the advisability of implementing the plan.
D Even if some of these materials produce little pollution, they nevertheless may produce some pollution. It may still be beneficial to reduce or eliminate this pollution.
E This indicates that these materials will most likely need to go into landfills. That does not call into question the advisability of recycling those materials that can be recycled.
The correct answer is B.
