Explain:
C: the threat will be eliminated结论不对，结论里面有修饰成分是不可以省略的，它表示范围，对选项至关重要
P1(hidden): we all complete the switchover from the old to the new plastic rings
P2: all beverage companies use only those rings consisting of a new plastic
Background: The plastic rings that hold six-packs of beverage cans together pose a threat to wild animals
Weaken: 1. Some company will not use the ring consisting of new plastic;
2. The beverage company cannot complete the switchover.
3. The reaction product of disintegrate from new plastic will threat the animals.
逻辑链：
2. Tiger sharks are common in the waters surrounding Tenare Island.(background)  Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.  This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues.(premise)  In order to help the economy,(hidden premise) therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.（conclusion）
Weaken: Tiger sharks are part of the food chain of fish industry; People come to see the tiger sharks; The number of people attacked by tiger sharks are not decreased after killing tiger sharks within a mile of the beaches.
3 The country of Ertland has never imported apples in any significant quantity because consumers there generally prefer the unique texture of Ertland-grown apples.（concession） Nevertheless, apple growers from Kosolia, a neighboring country, plan to sell their apples in Ertland(main conclusion) by selling Kosolia-grown apples at half the price of local apples and promoting them as a nourishing, low-cost alternative.(premise)
Weaken: People in Ertland buy apples considering texture more than price or nutrients; Ertland-grown apples sellers will decrease their prices, too; Nutrients cannot be distinguished through appearance.

1. 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
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


weaken
(A) The switchover to the new plastic rings will
take at least two more years to complete.
still can be done
(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.
suffocation仍热没被解决
(C) The new plastic rings are slightly less
expensive than the old rings.
strengthen the argument
(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.
strengthen
(E) The new plastic rings disintegrate into
substances that are harmful to aquatic
animals when ingested in substantial
quantities by them.
right

EXPLANATION: 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.

（借用别人的：仔细看了bible，悟了。。FOCUS ON THE CONCLUSION
B:conclusion说的是threat from plastic rings会减少，而不是threat from NEW plastic rings会减少，所以这里的threat=old+new！！！
E：这是个shell game。还是因为对conclusion不细致，the conclusion is specifically about suffocation, and the answer E doesn't address suffocation.）
