Beverage company representative: the plastic rings that hold six-packs
of beverage cans together pose a threat to wild animals, which often
become entangled in the discarded rings and suffocate as a result.
Following our lead, all beverage companies will soon use only those
ring consisting of a new plastic that disintegrates after only three
days' exposure to sunlight. Once we all complete the switchover from
the old to the new plastic rings, therefore, the threat of suffocation
that plastic rings pose to wild animals will be eliminated.
12. Which one of the following, if true, most seriously weakens the
representative's argument?
(A) The switchover to the new plastic rings will take at least two more
years to complete
(B) After the beverage companies have switched over to the new plastic
rings, a substantial number of the old plastic rings will persist in
most aquatic and woodland environments
(C) The new plastic rings are slightly less expensive than the old
rings
(D) The new plastic rings rarely disintegrate during shipping of
beverage six-packs because most trucks that transport canned beverages
protect their cargo from sunlight
(E) The new plastic rings disintegrate into substances that are harmful
to aquatic animals when ingested in substantial quantities by them
答案选b，可我认为B不足以作为一个削弱选项
因为实际上新的塑料拉环的确是可以减少威胁的，虽然有老的在那里不能分解掉
，可是由于新出来的拉环都是可以分解的，所以总的威胁还是少了很多。所以我
认为B只是一个陈述，不是一个削弱
