take at least two more years to complete.--------------------we talk about the situation when the company change to the new plastic rings,it’s irrelated

B
Note the carefully
worded nature of the conclusion—the representative does not say the threat
from new plastic rings will be eliminated, but rather the threat from plastic rings,
which includes both old and new rings.

1. 1min59s
Current Condition: Rings of beverage cans pose threats to wild animals.
Proposed plan: New beverage rings consist of a new plastic that disintegrates after 3 days’ exposure to sunlight.
Supposition: Threats to wild animals will be eliminated.
Weaken point: New plastic rings disintegrate into substances threaten to animals.

Nonononono......I assume that B is incorrect for even though new plastic was not used, old rings would exist, but I fails to consider that the aim of the proposed plan is to eliminate the suffocation of animals posed by plastic rings. Apparently, threatens to animals caused by substances disintegrated from plastic rings shouldn't be taken into account. Furthermore, the existence of old plastic rings means threatens of suffocation hasn't been eliminated.

2. 1min29s
Current Condition 1: Tiger sharks attack tourists and hurt T’s tourism industry.
Current Condition 2: Tourism industry is the 2nd to fishing industry in annual revenue.
Aim: To help the economy.
Proposed plan: Kill tiger sharks within a mile of the beaches.
Weaken point: Killing tiger sharks is harmful to fishing industry.

3. 1min41s
Current Condition 1: EPeople love E apples.
Proposed plan: K wants to sell K-apple to Epeople at half price of E apples.
Weaken point: E apples can also cut price.

4. 1min45s
Proposed plan: To move the station’s entrance to a low-rent adjoining side street and lease the high-rent entrance space to retail businesses.
Aim: To pay for those proposed renovation without negative impact on its tight budget.
Support point: Moving won’t cause less frequency of customers.

5. 1min28s
Premise: PZ 1000 has fewest injuries per accident of any car in its class.
Argument: PZ 1000 is one of the safest cars.
Weaken point: PZ 1000 are much more likely to be involved in accidents.

1）逻辑链
背景：绑六个啤酒瓶在一起的塑料绳对野生动物有威胁
措施：采用新的塑料绳，使得在太阳照射三天后分解
目的：塑料绳对野生动物的威胁就不存在了
2）推测
削弱
虽然绳子是不见了，但entangled in the discarded rings and suffocate的情况还是没有消失……
3）选项分析
A无关，与题目中的前提“once we all complete the switchover from the old to the new plastic rings”不符，题目中讨论的是转换了之后的
B无关，与题目中的前提“完全转换过来后”不符
C加强或无关
D无关，在shipping过程分不分解没有关系，只要一出来就可以分解就好了
E削弱，原来的问题解决了，但又产生了新的问题，因而还是不算是不存在威胁
感觉红色的三个很难分析，都有点像是正确答案，不知道最终结果对不对

4）错后反思
原来有一个理解错误，还有一个关键地位看漏
Once we complete the switchover，不代表说一定要旧的不存在对环境的影响了，只是说，我们不再使用旧的来包装了，那么由于之前旧的不容易分解，那他对环境的影响还是存在；
注意关注的是“the threat of suffocation”，而不是其他方面的threat，虽然E中提出了其他方面的threat，但这就与题目中的要求不相符了

2.
1）逻辑链
背景：tiger shark通常吃小shark，但偶尔也会攻击游客，对旅游业有影响，而旅游业是当地仅次于渔业的第二大收入
目的：拯救经济
措施：杀掉沙滩旁边一公里内的tiger shark
2）推测
削弱
这样子就使当地渔业收入受损
3）选项分析
A加强，说这一措施对旅游业有好处，进一步即对经济有好处
B加强
C加强
D削弱，说杀了tiger shark对渔业有影响
E无关

3.
1）逻辑链
背景：E地从来不大量进口苹果，因为当地消费者喜欢E地长的特殊口味的苹果
目的：为了在E地卖苹果
措施：以当地苹果的半价来卖
2）推测
削弱
措施是实施了，不过达不成目的
他们不缺钱，或者他们当地的水果价格已经很低了，E地百姓已经能买得起了，而且由于对口味的偏爱，愿意付这种稍高的价格去买
3）选项分析
A加强
B加强
C无关
D加强
E削弱，连K地唯一的优势价格都变得不存在了

4.
1）逻辑链
措施：将火车站入口从目前最有经济价值的Main Street入口挪到另外一个租金低的旁边的街，将那个租金高的入口让给零售业
目的：不影响其总支出的情况下，可以有多余的钱花在那些创新项目
2）推测
加强
Budget+火车收入+租金收入=创新项目
租金收入增加，budget不变，要创新项目的钱增加，则火车收入起码不能减少
3）选项分析
A削弱
B加强，说明对火车收入几乎没影响
C无关
D无关，或者削弱
E无关，虽然说火车乘客没什么便，但与题中的条件无关，题中条件说的是在出口转换的情况下

5
1）逻辑链
原因：在同种类型的车中，PZ1000有最少的injury
结论：PZ1000是最安全的车
2）推测
削弱：安全=injury+death
受伤的全都死了
3）选项分析
A加强
B无关或加强
C削弱，虽然在同种类型的车中，PZ1000的受伤最少，但这类型的车的事故率都很高，因而其实PZ1000还是不安全
D无关
E无关，无论你报的频率是怎么样的，最少的injury始终是
