BG: 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.
P: following the company's lead, all beverage companies will soon use only those rings consisting of a new       plastic that disintegrates after only three days' exposure to sunlight.
C: the threat of suffocating that plastic rings pose to wild animals will be eliminated
Weaken:  three days' exposure的不可实现性这里方向应该是threat 是否能被eliminate，而不简单是new plastic的好处
答案：D
A. 多少年实行VS是否有效  无关
B. 说old plastic的存在，跟new是否有效，无关
C. new比old便宜，只能说明价钱上的优势，不能说明是否有效
D. 说明new不能disintegrates,证明无效，correct
E.  对水生动物有害 VS 对all wild animals的有利，无关，而且不能weaken
答案B，注意选项中的plastic rings rarely disintegrate during shipping of beverage six-packs
because most trucks that transport canned beverages protect their cargo from sunlight里面的during，这里在during shipping之后plan还是能够实现，B出现题目的关键词，不细读内容容易被误导，而B中确实说明了OLD存在不能eliminate threat

1、
（1）逻辑链
     Background: plastic rings pose a threat to wild animals
     Premise: a new plastic can disintegrates after 3 days
     Conclusion: use the new plastic can eliminate the threat
（2）推测 weaken
     1\ animals 接触到plastic的时间通常在3days以内
     2\ 分解之后的物质仍有毒
（3）选项
     A、无关
     C、无关
     D、无关：运输期间分不分解无关
     E、这个思路跟猜测2相似，但是注意到它针对的是aquatic animals
        与题干的wild animals 不符

     答案：B 提供了一个新思路：在new plastic出来时，大量的old plastic要处理
             会影响aquatic 和woodland环境（包含了wild animal的生活环境）


2、  
（1）逻辑链
     Background: tiger sharks attack tourists
     Premise: T地的tourism industry 受影响
     Conclusion：kill any tiger sharks within a mile of the beaches
（2）推测 weaken
     1\ tiger S 吃 smaller S，program破坏了食物链平衡，smaller S increase，更加影响旅游
（3）选项分析
     A、support
     B、无关
     C、无关
     E、无关

     答案：D 跟猜测方向一致：不过它指向的是影响捕鱼业
                             （因为捕鱼业是no.1 而旅游只是no.2）

3、
（1）逻辑链：
     Background: E地的人prefer本地苹果，never import
     Premise：K地苹果nourishing and low cost
     Conclusion：K地农民想要sell their apples to E地的plan会成功
（2）推测  weaken
     1\ price low到还不如不出口卖给E地
       （也就是这个plan因为价太low而没有经济效益）
（3）选项分析
      A、support
      B、无关
      C、无关
      D、些许support的意味（some varieties of apples）

      答案：E weaken：plan中有价格优势，E地本地的price也可以下降，让你失去优势


4、
（1）逻辑链  
     premise：move the entrance to a low rent place and lease the high rent place to do businesses
     conclusion：easily pay for the renovations
（2）推测  support
     1\ this proposal can really get a lot of money
（3）选项分析

（这道题很不确定）


5、
（1）逻辑链
     Premise: PZ 1000 has the fewest injuries…..
     Conclusion: PZ 1000 is one of the safest
（2）推测  weaken
     1\ Fewest injuries 不等于 safe
       Few 只是数量上，真正的safe应该是发生车祸的严重程度
（3）选项分析
     A、support
     B、无关
     D、无关
     E、无关
     答案：C  PZ在这个class是最安全的，不代表在所有车里最安全
              因为也许PZ所在的class是车里最不安全的class

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
B: plastic rings pose a threat to wild animals by suffocating them
P1: all beverage companies will soon use new rings that will disintegrates after 3 days' exposure to sunlight
C: once the switchover is copleted, the threat will be elimilated

(A) The switchover to the new plastic rings will
take at least two more years to complete.
irrelavant: the conclustion states that once the switch over is completed

(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.D.E. irrelavant

B:tiger sharks are common around the T Island. Usually they feed on smaller sharks, but sometimes they attached tourists
P:Sharks' attack to tourists will hurt T's tourism industry

AB strengthen
CE irrelavant

The country of Ertland has never imported apples in any significant quantity because consumers there generally prefer the unique texture of Ertland-grown apples.  Nevertheless, apple growers from Kosolia, a neighboring country, plan to sell their apples in Ertland by selling Kosolia-grown apples at half the price of local apples and promoting them as a nourishing, low-cost alternative.

E: correct - it states that K apples cannot be a low cost alternative
BCD - irrelavant
(A) Most of the varieties of apples grown in Ertland were originally derived from common Kosolian varieties.
we need somthing that can undermine "nourishing, low cost alternative"
(E) Profiles of Ertland-grown apples are high enough in Ertland that growers, wholesalers, and retailers there could easily afford to reduce the price at which these apples are sold.

As part of major renovations to Flowertown's Main Street train station, consultants to the train company proposed moving the station's entrance from its current valuable Main Street location to a low-rent adjoining side street and then leasing the high-rent entrance space to retail businesses.  In that way, the train company could easily pay for those and all other proposed renovations without negative impact on its tight budget.
