Sales of telephones have increased dramatically over the lastyear. In order totake advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensiveadvertising of this product.

Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones byadopting the plan outlined above?

(A) Although it sells all of the telephones thatit produces, Mammoth Industries' share of all telephone sales has declined overthe last year.

(B) Mammoth Industries' average inventory oftelephones awaiting shipment to retailers has declined slightly over the lastyear.

(C) Advertising has made the brand name of MammothIndustries' telephones widely known, but few consumers know that MammothIndustries owns this brand.

(D) Mammoth Industries' telephone is one of threebrands of telephone that have together accounted for the bulk of the lastyear's increase in sales.

(E)Despite a slight decline in the retail price, sales of Mammoth Industries'telephones have fallen in the last year.

P: adpot the plan
    (expand production+ continue already extensive ads)
C: X increase sale

Answer:E
解析：
正确答案需要否定plan，因为Q： Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above
把不能increase sale的原因，归咎于Plan， 那么正确答案需要说出plan不好的地方
* special attetion tip: 逻辑中名词前面的modifier一定程度上表达了倾向，例如此题，already very extensive advertising of this product
E选项，尽管过去一年中电话的ads已经很intensive了，但是去年的销售还是下降了，那么continue ads（as part of the plan is useless)
A,sell all products,那么 expand production就可以继续sell, support the plan;
B, invetory 等待发货减少了，和销售量无关，说不定是物流进步了呢；
C,brand name irrelevant to plan above；
D，M的电话是去年卖的最好的三个品牌，那可能证明already extensive ads 是有效的，可以continue，不能否定plan；
自己不理解的原因：看选项就用过去 不等于 将来，排除了E项（谨记，千万不能用General rule来排除任何选项！case by case study ）

In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Some commentators have argued, correctly, that since there is presently no objective test for whiplash, spurious reports of whiplash injuries cannot be readily identified. These commentators are, however, wrong to draw the further conclusion that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious: clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.

In the argument given, the two boldfaced portions play which of the following roles?
AThe first is evidence that has been used to support a conclusion that the argument criticizes; the second is that conclusion.  分析A选项
BThe first is evidence that has been used to support a conclusion that the argument criticizes; the second is the position that the argument defends.  分析B选项
CThe first is a claim that has been used to support a conclusion that the argument accepts; the second is the position that the argument defends.  分析C选项
DThe first is an intermediate conclusion that has been used to support a conclusion that the argument defends; the second is the position that the argument opposes.  分析D选项
EThe first presents a claim that is disputed in the argument; the second is a conclusion that has been drawn on the basis of that claim.  分析E选项

In an attempt to promote the widespreaduse of paper rather than plastic, and thus reduce nonbiodegradable waste, thecouncil of a small town plans to banthe sale of disposable plastic goods for whichsubstitutes made of paperexist. The council argues that since most paper is entirely biodegradable, paper goods are environmentally preferable.

Which of the following, if true, indicates that the planto ban the sale of disposable plastic goods is ill suited to the town council’s environmental  goals?

(A)       Althoughbiodegradable plastic goods are now available, members of the town council believe biodegradable paper goods to be safer for the environment.

(B)       Thepaper factory at which most of the townspeople are employed plans to increase production of biodegradable paper goods.

(C)       Afterother towns enacted similar bans on the sale of plastic goods, the environmentalbenefits were not discernible for several years.

(D)       Sincemost townspeople prefer plastic goodsto paper goods in many instances,theyare likely to purchasethem in neighboring towns where plastic goods are available for sale.

(E)       Productsother than those derived from wood pulpare often used in the manufacture of paper goods that are entirelybiodegradable.

P:plans to ban the sale of disposable plastic goods
C:to promote the widespread use of paper,and thus reduce nonbiodegradable waste

OA:  D

The town council’s plan is, however, only as effective as the support it has from the town’s citizens. If the citizens prefer disposable plastic goods and if the goods are also readily available in neighboring towns, there is nothing to stop them from buying the plastic goods elsewhere if that is their preference.

Electric utilities pay less for low-quality coal per ton delivered than for high-quality coal. Yet more low-quality coal   than high—quality coal must be burned to generate the same amount of electricity. Moreover, per ton of coal burned, low-quality coal generates more ash than does high-quality coal, and the disposal of ash is becoming more and more expensive.

The considerations above, if true, most strongly support which of the following claims?

A.   A coal-burning utility might not be assured of benefiting economically by always adhering to the policy of keeping its overall coal purchasing costs as low as possible.

B.  In those regions where the cost of disposing of coal ash is negligible, it is more expensive for coal-burning utilities to use high-quality coal than low-quality coal.

C. Transportation costs represent a smaller proportion of the cost per delivered ton for low-quality coal than for high-quality coal.

D. It is no less expensive to dispose of a ton of coal ash that results from the burning of high-quality coal than it is to dispose of a ton of coal ash that results from the burning of low-quality coal.

E. In regions where coal-ash disposal is the least expensive, reserves of low-quality coal are likely to decline at a faster rate than are reserves of high-quality coal.

T-4-Q2Twenty years ago, Balzania put in place regulations requiring operators of surface mines to pay for the reclamation of mined-out land.Since then, reclamation technology has not improved.Yet, the average reclamation cost for a surface coal mine being reclaimed today is only four dollars per ton of coal that the mine produced, less than half what it cost to reclaim surface mines in the years immediately after the regulations took effect.

Which of the following, if true, most helps to account for the drop in reclamation costs described?

A. Even after Balzania began requiring surface mine operators to pay reclamation costs, coal mines in Balzania continued to be less expensive to operate than coal mines in almost any other country.
B. In the twenty years since the regulations took effect, the use of coal as a fuel has declined from the level it was at in the previous twenty years.
C. Mine operators have generally ceased surface mining in the mountainous areas of Balzania because reclamation costs per ton of coal produced are particularly high for mines in such areas.
D. Even after Balzania began requiring surface mine operators to pay reclamation costs, surface mines continued to produce coal at a lower total cost than underground mines.
E. As compared to twenty years ago, a greater percentage of the coal mined in Balzania today comes from surface mines.
