1. Advertisement: At most jewelry stores, the person
assessing the diamond is the person selling it so
you can see why an assessor might say that a
diamond is of higher quality than it really is.
But because all diamonds sold at Gem World
are certified in writing, you’re assured of a fair
price when purchasing a diamond from Gem
World.
计时：20.70s
逻辑链：珠宝店鉴定宝石的人就是卖宝石的人，所以他们总是把宝石的质量说的比较好。但是因为GW的宝石是有证书的，所以顾客可以确保宝石的价格是fair的

The reasoning in the advertisement would be most
strengthened if which one of the following were true?
(A) Many jewelry stores other than Gem World also
provide written certification of the quality of
their diamonds. 无关
(B) The certifications of diamonds at Gem World
are written by people with years of
experience in appraising gems. 正确
(C) The diamonds sold at Gem World are generally
of higher quality than those sold at other
jewelry stores. 无关

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of ice and enough seawater, which contains nutrients, reaches that layer after splashing onto the surface.  Even though moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.
推测：要找一个可以解释为什么snow cover可以使得algae增多的选项

Which of the following, if true, most helps to explain the apparent discrepancy?
(A) As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow. 正确
(B) Seawater in the Antarctic often contains higher concentrations of nutrients than does seawater in more temperate regions. 无关
(C) As the air temperature around sea ice decreases during the winter, the likelihood decreases that snow will fall and thus add to any existing snow cover. 无关
(D) The nutrients on which algae rely are common in seawater throughout the Antarctic. 无关
(E) More sunlight filters through a layer of ice than through an equally thick layer of snow.

Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees' cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo does not have the same financial incentive to adopt such a policy, because __________.
(A) early treatment of high cholesterol does not entirely eliminate the possibility of a stroke later in life 错误 不完全消除但是还是比不消除好
(B) the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol 无关
(C) RenCo has significantly more employees than Garnet has 削弱
(D) RenCo's employees are unlikely to have higher cholesterol levels than Garnet's employees比较无关
(E) the average length of time an employee stays with RenCo is less than it is with Garnet 正确

United Lumber will use trees from its forests for two products.  The tree trunks will be used for lumber and the branches converted into wood chips to make fiberboard.  The cost of this conversion would be the same whether done at the logging site, where the trees are debranched, or at United's factory.  However, wood chips occupy less than half the volume of the branches from which they are made.
The information given, if accurate, most strongly supports which of the following?
(A) Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site. 新消息
(B) It would be more economical to debranch the trees at the factory where the fiberboard is manufactured. 正确
(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site. 新消息
(D) Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory. 反信息
(E) In the wood-processing industry, branches are used only for the production of wood chips for fiberboard.未知

Which of the following most logically completes the argument?
Utrania was formerly a major petroleum exporter, but in recent decades economic stagnation and restrictive regulations inhibited investment in new oil fields.  In consequence, Utranian oil exports dropped steadily as old fields became depleted.  Utrania's currently improving economic situation, together with less-restrictive regulations, will undoubtedly result in the rapid development of new fields.  However, it would be premature to conclude that the rapid development of new fields will result in higher oil exports, because __________.
推测：要找一个能说明为什么有新的开采点但是出口不一定会增加的选项
(A) the price of oil is expected to remain relatively stable over the next several years 无关
(B) the improvement in the economic situation in Utrania is expected to result in a dramatic increase in the proportion of Utranians who own automobiles 正确 汽车多了 国内用油量增加
(C) most of the investment in new oil fields in Utrania is expected to come from foreign sources
(D) new technology is available to recover oil from old oil fields formerly regarded as depleted 削弱
(E) many of the new oil fields in Utrania are likely to be as productive as those that were developed during the period when Utrania was a major oil exporter 削弱
