标题: 【每日逻辑链练习贴】【逻辑2-4】
今天第一天接替抓~~大家多多支持呀~~吼吼~~
貌似咱们没有做过BF题呀~~我BF题一般必死~~哎哎~~~加一道BF好了~~
1【大全-A-2】. Which of the following best completes the passage below?
One tax-reform proposal that has gained increasing support in recent years is the flat tax, which would impose a uniform tax rate on incomes at every level. Opponents of the flat tax say that a progressive tax system, which levies a higher rate of taxes on higher-income taxpayers, is fairer, placing the greater burden on those better able to bear it. However, the present crazy quilt of tax deductions, exemptions, credits, and loopholes benefits primarily the high-income taxpayer, who is consequently able to reduce his or her effective tax rate, often to a level below that paid by the lower-income taxpayer. Therefore, ______

Answer：the progressive nature of our present tax system is more illusory thanreal
2.【大全2-2-1】After the national speed limit of 55miles per hour was imposed in 1974, the number of deaths per mile driven on ahighway fell abruptly as a result. Since then, however, the average speed ofvehicles on highways has risen, but the number of deaths per mile driven on ahighway has continued to fall.
Which of the following conclusions can beproperly drawn from the statements above?

Answer：The speed limitalone is probably not responsible for the continued reduction in highway deathsin the years after 1974.
3.【大全2-2-2】Neighboring landholders: Air pollutionfrom the giant aluminum refinery that has been built next to our land iskilling our plants.
Company spokesperson: The refinery is notto blame, since our study shows that the damage is due to insects and fungi
Which of the following, if true, mostseriously weakens the conclusion drawn by the company spokesperson?

Answer：Air pollutionfrom the refinery has changed the chemical balance in the plants’ environment,allowing the harmful insects and fungi to thrive.

4.[GWD #29-Q28]Astronomer: Observations of theShoemaker-Levi comet on its collision course with Jupiter showed that the cometbroke into fragments before entering Jupiter's atmosphere in 1994, but they didnot show how big those fragments were. In hopes of gaining some indication of the fragments' size, astronomersstudied spectrographic analyses of Jupiter's outer atmosphere. These analyses revealed unprecedented tracesof sulfur after the fragments' entry. The fragments themselves almostcertainly contained no sulfur, but many astronomers believe that the cloudlayer below Jupiter's outer atmosphere does contain sulfur. Since sulfur would have seeped into the outeratmosphere if comet fragments had penetrated this cloud layer, it is likelythat some of the fragments were at least large enough to have passed throughJupiter's outer atmosphere without being burned up.

Answer:The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion

5.The following appeared aspart of an article in a magazine devoted to regional life.
“Corporations should look to the city of Helios when seeking newbusiness opportunities or a new location. Even in the recent recession,Helios’s unemployment rate was lower than the regional average. It is theindustrial center of the region, and historically it has provided more than itsshare of the region’s manufacturing jobs. In addition, Helios is attempting toexpand its economic base by attracting companies that focus on research anddevelopment of innovative technologies.”

1.【1‘20s】一个税收改革要向不同收入阶层的人征收同样的税。--》但是有反对者认为，根据收入不同来征收不同的税会更加公平。--》但是，。。。的收入是来自于高收入者的税收，因为高收入者交的税往往比低收入者的多。因此：根据不同的收入层次征税不一定更加的公平。
2.【30s】自从限速政策在1949年开始实施以后，每公里的死亡人数有很大的下降--但是，自从之后，车的平均速度都提高了，但是每公里死亡率还是下降的。
Conclusion：大部分的死亡都是由于高于限速的速度导致的。
3.【20s】地主：因为旁边的铝厂排放的污染气体杀死了我们的植物。
公司，经过我们的调查，不是空气造成死亡，而是植物和细菌造成了植物的死亡。
weaken：污染的气体引起了植物和细菌的滋生。
4.【1’30s】宇航员：在研究彗星撞击的碎片到木星上的时候，无法估计碎片的大小。--》因此科学家开始研究，发现本身不带有S的碎片，带有S。--》而木星大气中有S，只有当碎片穿过大气，进入木星的时候，碎片才会包含S。--》所以，有些碎片足够大到进入木星大气时，并没有完全的燃烧掉。
第一个：支持结论的论据
第二个：结论。

1 43s
premise:以前递增的纳税方法，由于对于高收入的人群有很多的利好政策，使得他们比低收入的有效税率更低
conclusion：要实行统一税率

2 44s
premise：限速之后，highway per mile死亡率下降，但是平均速度上升了，还是下降
conclusion：死亡率是由于高于限速的那部分速度导致的

3 45s
premise:insects 影响了植物的生长
conclusion the refinery should not to blame

weaken: 附近的insect都是由于the refinery 带来的

4 看不懂啊，放弃啊
这一道题first bolfold is finding ，第二个一个evidence/claim support the astronant argument

premise：有一个彗星的撞击，想测量碎片的额size,因为some of the fragments were at least large enough to have passed throughJupiter's outer atmosphere without being burned up.
conclusion： many astronomers believe that the cloudlayer below Jupiter's outer atmosphere does contain sulfur.

5 38s

1. 48s 这个对于学过税收的孩子太有优势了，哇哈哈哈
Premise: Some people say it is better to enforce a flat tax rate
Premise: Opponents believe progressive rate is more desirable
Premise: However, tax deduction and exemptions always make higher-level earners benefit a lot from progressive tax

Conclusion: Progressive tax is not really good.

2. 25s 哈哈哈,balapupu的题太好了，连着两个推对答案
Premise: After the speed limit enforced in 1974, death rate fell.
Premise: Even after the speed has stead increased, death rate still fell.

Conclusion: The speed limit is not responsible for the fall.

3. 23s 我要高兴坏了= =
Conclusion: The factory is not to blame, since the death is caused by fungi

Weaken: No factory, there would be no fungi.

4. 1min 彻底高兴了- -
Purpose: To study how big the size of fragment is
Conclusion: It is likely that some fragments are just big enough to penetrate the Jupiter
Premise: Outlayer has no sulfur, but if the fragments has, then support the conclusion

To balapupu~BF题建议看下PowerScore的总则那两章(2,3章)，然后再看下boldface题那章就好。~
其实总则那两章是适用于所有逻辑题的，把那几点都吃透了，所有的逻辑题都好办多了~

Company spokesperson: The refinery is notto blame, since our study shows that the damage is due to insects and fungi
Which of the following, if true, most seriously weakens the conclusion drawn by the company spokesperson?

问题：科学家不知道木星的旁边的碎片有好大。
前提：一次探索发现碎片上有硫，而碎片自己没有没有硫，木星下层的大气里有。
结论：这个碎片大的可以进入木星。

前句是支持结论的条件，后句是结论。
The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion 拆分结构

1.政府将税率改为平滑型，任何档次的税率都相同。反对者认为还是应该采用层次型税率，更高的收入付更高的税，因为高收入者对税率的忍耐力更强。但是，各种疯狂的避税行为，使得高收入者交的税比低收入者还少，所以。。。。还是该采用平滑型，因为平滑型最起码是一样的

2. 自从政府在某年将速度限制在55，每公里的车祸死亡率下降了，但是自从那时刻开始，车的平均速度上升了，但是死亡率依然下降，得到：不知道啊

3.铝炼厂的空气污染正在杀死植物
不该责备工厂，真正的凶手是细菌和昆虫
削弱：污染会导致细菌昆虫增加或者。。。

4。第一个是得到的现象第二个是解释第一个现象

5.应该去helio投资失业率低工业的中心打算扩展新的创新技术

1.1'20''
P There are many benefits on tax to high-income people that they often pay less tax than lower-income people
C
complete the argument:The high-income people should pay more tax than lower-income people; The should be some same benefits for lower-income people; The benefits for high-income people should be dismissed.
标准答案：所以说那个gradual的也是十分不合理的

2.46s
P The average speed of vihicles has risen, but the number of dealth rate has continue falling.
conclusion:The rising speed of the vihicles did not surpass the limitation.
标准答案：切断了因果关系相关性不存在另一段时间速度增加了但是死亡率还是一直在下降
3 40s
neighbor: The air pollution is responsible for killing the plants.
company: The fungi and insects are responsible for killing the plants.
weaken:从前也一直有fungi和insects 但植物没有被杀害
pollution-insect和fungi-killing the plants
大BOSS还是工厂的pollution
4.60s
The first: fact set support the conclusion.
The second: conclusion
5.
1) The lower unemployment rate in H does not mean that H would provide new business opportunities or a new location for corporations. There are others things corporations should know before drawing the conclusion.
2) That H has provided more than its share of the region's manufacturing jobs historically does not mean H will continue to provide. Other factors in the environment would affect.
3) H want to attract companies that focus on research and development of innovative technologies. We do not know which domain do the corporations good at. And before knowing whether the corporations are suitable for H, it is imprudent to dram the conclusion.

1. 超时
BG1: 税收改革向不同收入阶层的人征收同样的税，受到了越来越多的支持
BG2：反对者觉得向高收入者正更多的税会更公平
Premise: 然而实际上由于各种原因高收入者被征的税比低收入者少得多。
Conclusion: 所以这个情况会更加不合理，应该向高收入者正更多的税。

2、38s
BG1: 1978年后实施国家55km/h的高速限速规定之后，交通事故死亡率急剧下降。
BG2：但是从那以后高速上的车辆均速有增加，但是交通事故死亡率还是在下降。
Conclusion: 因此造成交通事故死亡率增加的主要是那些超出最高限速的车辆。

3. 30s
农民说：我们的庄稼收成不好是因为旁边的铝制品加工场的空气污染导致的、
工厂说：你们收成不好我们调查过了，不管我们的事，主要是因为虫害和真菌。

Weaken: 是由于工厂的废气污染直接导致了害虫和真菌的增加。

4。超时
BG1: 天文学家在研究某彗星撞向木星时，彗星的大小。
premise1:该彗星在进入木星外大气层的时候就已经裂为碎片.
Premise2：研究表明在彗星撞向木星之后，木星的外大气层里含有硫。
Premise3): 该彗星碎片本身是不含硫的，而木星大气层下方的云层是含有硫的。
Premise 4: 如果彗星碎片穿过木星大气层的话，就会把硫渗入云层。
Conclusion: 因此推测，该彗星至少是在其燃烧光之前是穿过了木星的大气层的。
1）支持结论的论据 2）结论
