The Maxilux car company's design for its new luxury model, the Max 100, included a special design for the tires that was intended to complement the model's image. The winning bid for supplying these tires was submitted by Rubco. Analysts concluded that the bid would only just cover Rubco's costs on the tires, but Rubco executives claim that winning the bid will actually make a profit for the company.
Which of the following, if true, most strongly justifies the claim made by Rubco's executives?
In any Maxilux model, the spare tire is exactly the same make and model as the tires that are mounted on the wheels.
Rubco holds exclusive contracts to supply Maxilux with the tires for a number of other models made by Maxilux.
The production facilities for the Max 100 and those for the tires to be supplied by Rubco are located very near each other.
When people who have purchased a carefully designed luxury automobile need to replace a worn part of it, they almost invariably replace it with a part of exactly the same make and type.
When Maxilux awarded the tire contract to Rubco, the only criterion on which Rubco's bid was clearly ahead of its competitors' bids was price.

④选项分析：答案问选项中哪一个更能支持R公司总裁的发言，R公司总裁宣布赢得这种轮胎的标实际上将会为公司赚取利润，要能支持这一论断必须使轮胎的制作和M汽车公司生产的汽车挂钩。选项A：在M的任何一种车型中，备用轮胎和安装在车轮上的轮胎在制作和铸模方面都是完全一样的，其他车型的轮胎跟R公司的竞标没有任何关系，无关选项。
选项B：R公司和M公司签订的合同还有为M公司其他几种车型提供轮胎都与这种轮胎的中标无关。选项C：Max 100的生产设备和R所提供的轮胎的生产设备离得非常近，生产设备的问题和R的这次竞标能不能赚钱没有任何关系。只有选项D当那些买了精心设计的豪华轿车的人需要更换轮胎的时候，他们通常都会更换在制作以及铸模方面完全一样的轮胎(也就是原装轮胎喽)支持了结论。

Which of the following most logically completes the passage?
Most bicycle helmets provide good protection for the top and back of the head, but little or no protection for the temple regions on the sides of the head. A study of head injuries resulting from bicycle accidents showed that a large proportion were caused by blows to the temple area. Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced, especially since .
among the bicyclists included in the study's sample of head injuries, only a very small proportion had been wearing a helmet at the time of their accident
even those bicyclists who regularly wear helmets have a poor understanding of the degree and kind of protection that helmets afford
a helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets
the bone in the temple area is relatively thin and impacts in that area are thus very likely to cause brain injury
bicyclists generally land on their arm or shoulder when they fall to the side, which reduces the likelihood of severe impacts on the side of the head

④选项分析：Which of the following most logically completes the passage?说明题目为解释类题目，提干说一个自行车车祸造成头部受伤的研究显示，大部分的受伤都是由于颞部的撞击引起的。那么要解释为什么自行车头盔能够降低头部受伤的危险就很容易了，这是一个正向解释。选项A说在那些研究调查的自行车手当中，只有很小的一部分在出车祸的时候戴了头盔。但是只有很少的带了头盔也不能说明头盔能够降低头部受伤的危险。因为没有给出结果数据。选项B人们了不了解头盔的保护能力和能否降低头部受伤的风险没有任何关系。
选项C只说明头盔的特性和结论无关。选项E跌倒的姿势会降低对头不造成伤害的可能性。与头盔无关，是无关选项。所以选项D正确。

In order to reduce the number of items damaged while in transit to customers, packaging consultants recommended that the TrueSave mail-order company increase the amount of packing material so as to fill any empty spaces in its cartons. Accordingly, TrueSave officials instructed the company's packers to use more packing material than before, and the packers zealously acted on these instructions and used as much as they could. Nevertheless, customer reports of damaged items rose somewhat.
Which of the following, if true, most helps to explain why acting on the consultants' recommendation failed to achieve its goal?
The change in packing policy led to an increase in expenditure on packing material and labor.
When packing material is compressed too densely, it loses some of its capacity to absorb shock.
The amount of packing material used in a carton does not significantly influence the ease with which a customer can unpack the package.
Most of the goods that TrueSave ships are electronic products that are highly vulnerable to being damaged in transit.
TrueSave has lost some of its regular customers as a result of the high number of damaged items they received.

④选项分析：TS公司增加包装材料，以减少货物在运途中的损坏，但结果却是货物损坏数量却增多了。要解释这种现象，来回答为什么顾问的建议没能成功的达到目的。首先明确，顾问建议的目的是使货物看上去充实，增加销售量。选项A说包装材料费和包装工人费的增加，无结论关项。选项B说包装材料被压得太紧，失去了减震的作用，与没有增加销量无关。选项C说包装材料对收货者拆开包装的影响，与结论无关。选项D说TS公司所运送的大多数都是易碎的电子产品，根据实际情况，该公司前后应当运送的同样的商品，也没有解释包装材料使包装材料的问题。选项E说TS公司失去了一些顾客，因为运输损坏量太高。这是没能达到目的原因。

Wood smoke contains dangerous toxins that cause changes in human cells. Because wood smoke presents such a high health risk, legislation is needed to regulate the use of open-air fires and wood-burning stoves.
Which of the following, if true, provides the most support for the argument above?
The amount of dangerous toxins contained in wood smoke is much less than the amount contained in an equal volume of automobile exhaust.
Within the jurisdiction covered by the proposed legislation, most heating and cooking is done with oil or natural gas.
Smoke produced by coal-burning stoves is significantly more toxic than smoke from wood burning stoves.
No significant beneficial effect on air quality would result if open-air fires were banned within
the jurisdiction covered by the proposed legislation.
In valleys where wood is used as the primary heating fuel, the concentration of smoke results
in poor air quality.

A certain automaker aims to increase its market share by deeply discounting its vehicles' prices for the next several months. The discounts will cut into profits, but because they will be heavily advertised the manufacturer hopes that they will attract buyers away from rival manufacturers' cars. In the longer term, the automaker envisions that customers initially attracted by the discounts may become loyal customers.
In assessing the plan's chances of achieving its aim, it would be most useful to know which of the following?
Whether the automaker's competitors are likely to respond by offering deep discounts on their own products
Whether the advertisements will be created by the manufacturer's current advertising agency
Whether some of the automaker's models will be more deeply discounted than others
Whether the automaker will be able to cut costs sufficiently to maintain profit margins even when the discounts are in effect
Whether an alternative strategy might enable the automaker to enhance its profitability while holding a constant or diminishing share of the market
