14. 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
(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
(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.
D is not, because the products produce least pollution when incinerated; least when compared to the rest of the products. it may still be producing substantial pollution which can be avoided by recycling.
