1. Beverage company representative:The plastic rings
that hold six-packs ofbeverage cans together
pose a threat to wild animals,which often
become entangled in thediscarded rings and
suffocate as a result.Following our lead, all
beverage companies will soonuse only those
rings consisting of a newplastic that
disintegrates after only threedays’ exposure to
sunlight. Once we all completethe switchover
from the old to the newplastic rings, therefore,
the threat of suffocation thatplastic rings pose
to wild animals will beeliminated.
Which one of the following, iftrue, most seriously
weakens the representative’sargument?  
--BIBLE WEAKEN NO.2
P: other companies use not-integrated six-pack rings. Our companyuses disintegrated rings. We persuade other companies to switch to ourproducts.
C: threat to environment will be eliminated.
Prepharase: new rings are still harmful to environment.

during shipping of beveragesix-packs
because most trucks thattransport canned
beverages protect their cargofrom sunlight.
(E) The new plastic rings disintegrate into
substances that are harmful to aquatic
animals when ingested in substantial
quantities by them. A perfect example of a Shell Game. Do not generalize! Many testtakers read the conclusion and think, “So when they start using these newrings, it will make things better for
the animals.”

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
rings 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.
Which one of the following, if true, most seriously
weakens the representative’s argument?
--BIBLE WEAKEN NO.2
37s---选错--错因，没有注意文中的关键词，而是把题目generalize。topic是关于suffocation， 而不是threat to the wild animals，认真读conclusion！
background：beverage container pose a threat to wild animals
premise: 某公司有一种方法是污染物在太阳下，几天的时间expose
conclusion: 采用这种方法，从旧的过渡到新的，可以减少对wild animal的伤害
weaken：某container消失之后产生气体污染，threat to animals；

选项：
(A) The switchover to the new plastic rings will
take at least two more years to complete.  结论是关于swichover结束之后的。--关注结论的时间范围
(B) After the beverage companies have switched
over to the new plastic rings, a substantial
number of the old plastic rings will persist    weaken对象是，这种过渡能够减少，而不是关于原来的剩余的影响
in most aquatic and woodland environments.
(C) The new plastic rings are slightly less
expensive than the old rings.     无关
(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.  无关
(E) The new plastic rings disintegrate into
substances that are harmful to aquatic  
animals when ingested in substantial
quantities by them.    与预测相符----shell game---选错

Answer choice (E): This is the most commonly chosen answer, and it is a
perfect example of a Shell Game. In this case, the answer preys upon test takers
who fail to heed Primary Objective #4: “Read closely and know precisely what
the author said. Do not generalize!” Many test takers read the conclusion and
think, “So when they start using these new rings, it will make things better for
the animals.” When these test takers get to answer choice (E), the answer looks
extremely attractive because it indicates that the implementation of the new
rings will also have a harmful effect. With this thinking in mind, many test
takers select answer choice (E) thinking it undermines the conclusion and they
are certain they have nailed the question. However, the conclusion is
specifically about suffocation, and answer choice (E) does not address
suffocation. Instead, answer choice (E) is a shell game that attacks a conclusion
that is similar but different than the actual conclusion. Remember, one of the
rules for weakening arguments is to focus on the conclusion, and knowing the
details of the conclusion is part of that focus.

Finally, the placement of answer choice (E) is no accident. Most students do not
immediately identify answer choice (B) as the correct answer, and even those
that keep it as a Contender often feel it could be stronger. Then, just when
things are starting to look bleak, answer choice (E) pops up sounding fairly
reasonable. Most people breathe a sigh of relief and select the answer without
carefully examining the contents. Never choose answer choice (E) just because
the first four answers are not overly attractive! Always make a thorough
analysis of every answer choice and remember that the test makers know that
people get nervous if none of the first four answer choices jump out at them. Do
not let the test takers draw you into a trap!
