GWD-8-Q19: GWD-2-12
Which of the following most logically completes the passage?
Concerned about financial well-being of its elderly citizens, the government of Runagia decided two years ago to increase by 20 percent the government-provided pension paid to all Runagians over 65. Inflation in the intervening period has been negligible, and the increase has been duly received by all eligible Runagians. Nevertheless, many of them are no better off financially than they were before the increase, in large part because ________.
事实一：为了资助老年人很好的生活，R地政府在两年前决定将对超过65岁居民的退休金提高20%。
事实二：通货膨胀因素不考虑进去
事实三：所有符合条件的R地居民都按这个标准领取到了退休金。
事实四：这些老人的生活并没有比提高退休金前过得更好。
主要的原因是：
A. They rely entirely on the government pension for their income 如果是这样的话，那增加的百分之二十就等于他们的全部收入增加了百分之二十。为什么增加了还和没增加时一样呢?此选项不能回答这个问题。
B. Runagian banks are so inefficient that it can take up to three weeks to cash a pension check 银行没效率只是把老年人把取现的时间往后推了三个星期，可是帐户里面增加了百分之二十不会因为这三个星期就变得没有了。所以仍然无法回答这个问题。
C. They buy goods whose prices tend to rise especially fast in times of inflation.这个因素已经在题干里说了不做考虑。
D. The pension was increased when the number of elderly Runagians below the poverty level reached an all-time high.如果现在仍然很穷，那么以前就是比很穷还穷，那么还是应该是生活有所改善了，只是改善的可能还不够，但不能回答问题。
E. In Runagia children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living 政府给的多了，孩子就给的少了。所以老人实际收到的还是和以前一样。
GWD-8-Q21:GWD-2-18
Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residue ash. In order to reduce the amount of residue ash Shelbyville generates this year to half of last year’s total, the city has revamped its collection program. This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.
去年所有被S城市服务部门收集的垃圾都是被灰化了。因为灰化的过程会产生大量的残渣灰末。为了将残渣灰末的数量减少到去年的一半，S城修改了它的收集垃圾程序。今年城市服务中心将把垃圾按回收、不可回收的分类，以把需要灰化的垃圾数量(按运送的车载量计算)减少到去年的一半。
Which of the following is required for the revamped collection program to achieve its aim?
A. This year, no materials that city services could separate for recycling will be incinerated. 今年，没有可以回收的垃圾被拿去灰化。(这个我不知道怎么排除掉，但和D比起来，好象D更有说明力，就先这么放这儿吧。如果你有好的意见，希望发短信给我。)
B. Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it cost last year to dispose of the residue ash. 这儿没有讨论处理垃圾费用的问题，无关。
C. Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year. 去年垃圾没回收，所以无法比较。
D. The refuse incinerated this year will generate no more residue ash per truckload incinerated than did the refuse incinerated last year. 正确。如果今年烧的垃圾少了，但是平均产生的灰更多了，那么就和结论不一致。
E. The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year. 总共的数量即使超过去年的不要紧，关键是分类后拿去烧的减少一半就够了。
GWD-8-Q22:
When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins. Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.
当保存文艺复兴时期油画作品时，博物馆有统一的标准将环境温度和湿度控制在很少的变化范围内。维持这样的环境是非常花钱的，而且最近的研究表示即使是年代已久的油画涂料也不会因为温度和湿度大的波动而受到影响。因此，博物馆是不需要花这么多钱而同时也可以保护好那些油画的。
Which of the following is an assumption on which the argument depends?
Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards. 刚完成的油画和很多年前完成的油画是不是一样的我们不知道，因为题干没说。所以不能拿这两种来比较。
Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all. 结论是要想证明不需要花这么多钱可以达到同样的效果，而不是说现在花了钱还没有好的效果。
Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.题干就已经说了是针对文艺复兴时期的作品，其它作品没那么熊猫待遇是可能的，但是却无关。
None of the materials in Renaissance oil paintings other than the paint are vulnerable enough to relatively wide fluctuations in temperature and humidity to cause damage to the paintings.正确。既然涂料是最容易受影响的，那么如果涂料不受影响就说明油画就没问题
Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created. 同一个地区不是问题，不同的时代才是重点所在。
GWD-8-Q31: GWD-2-12’
Which of the following most logically completes the argument?
Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour. Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers. Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____.
Y和Z两个公司都有很多按小时计算工资的工人。向社会公开的数据表明两个公司的计时工人数是几乎一样的，但Y公司的年工资支出却大大超过Z公司的工资支出。因为，Y公司所支付给计时工的平均工资比Z公司的高，因为。。。。。。。
Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages 这个是说Z公司付的不一定比Y公司少，明显唱反调，错误。
the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does 两个公司对计时工的技术要求都一样。这个选项是想让你想念Z公司对工人不够意思，可是却不能证明Y公司的确付给计时工的平均工资高于Z公司，所以错误。
the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech 计时工和总雇工人数比没有意义，因为题中限定的是两个公司支付给小时工的工资，而没有比较总工资支出。
overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech 两个公司都没有占相当比例的加工工资。如果有的话，那么两个公司尽管计时工的人数一样，但工作时间数量就不一样，这个选项排除了这个可能。正确。
the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech 最高工资的比较不说明平均工资的情况。
GWD-8-Q33:
In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle populations, even though they seldom burrow.
为了不止于被海浪卷走，未成年的H蟹经常在沙滩上挖洞，挖洞这个动作让B不能粘在H蟹的壳上。当这种蟹完全长成后，它们就不再担心被浪卷走----》所以它们也就不挖洞了---》所以它们身上的B就多了。但是让人奇怪的是，在海浪弱的地区，未成年的的蟹身上并没有很多的B，尽管它们很少挖洞。
Which of the following, if true, most helps to explain the surprising finding?
Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.这个题干中已经说了，是挖洞这个动作，而和海浪没关系。
Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest. 那么为什么B反而少呢?没有解释这个现象。
The strength of the tidal currents in a given location varies widely over the course of a day.不管一天中哪个时间浪高，反正现在的情况是未成年的蟹身上没有B，这是为什么?显然这个选项也没有回答这个问题。
A very large barnacle population can significantly decrease the ability of a horseshoe crab to find food. B有什么坏处和好处都不要紧，关键是要弄清楚为什么在B本来应该多的情况下却不多?
Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year. 不是B少了，而是蟹经常换壳，所以沾上归沾上，一会儿就壳带B全掉了。正确。
