如果看过小编前面的分析的同学肯定知道下面GWD逻辑题目的解题思路，不熟悉的同学也可以翻看一下前面的文章。当然如果大家有时间也建议大家把小编提到的题目整理成册，方便练习。
GWD-9-Q8:
Many large department stores in Montalia now provide shopping carts for their customers. Since customers using shopping carts tend to buy more than those without shopping carts, most of these stores are experiencing strong sales growth, while most other department stores are not. Therefore, in order to boost sales, managers of Jerrod’s, Montalia’s premier department store, are planning to purchase shopping carts and make them available to the store’s customers next month.
M地的一些大型百货公司为顾客提供了购物推车。因为用购物车的顾客比没有用的倾向于购买更多的商品。因此，为了提高销售额，M地最好的(还是最大的?)百货公司---J百货公司的经理计划在下个月也开始在为顾客提供购物推车
Which of the following, if true, casts most doubt whether the managers’ plan, if implemented, will achieve its goal?
Since most customers associate shopping carts with low-quality discount stores, Jerrod’s high-quality image would likely suffer if shopping carts were introduced. 也就是说如果J公司出现了推车，那么以前的顾客有可能就不来了。正确。
Because the unemployment rate has declined to very low levels, Jerrod’s now has to pay significantly higher wages in order to retain its staff.此题中，销售额和工资支出，甚至和利润率都不发生联系。
A number of department stores that did not make shopping carts available to their customers have had to close recently due to falling profits. 也就是说不提供购物推车就可能赚不了钱，赚不了钱就可能关门。那J公司不是就该提供吗?可现在要找的答案是说J公司提供了不一定能提高销售额。显然此项在唱反调。
Shopping carts are not very expensive, but they generally need to be replaced every few years. 购物推车的购买成本和管理成本不在本题讨论范围内。
Stores that make shopping carts available to their customers usually have to hire people to retrieve the carts from parking areas.同D。
GWD-9-Q12:
A mosquito bite can transmit to a person the parasite that causes malaria, and the use of mosquito nets over children’s beds can significantly reduce the incidence of malarial infection for children in areas where malaria is common. Yet public health officials are reluctant to recommend the use of mosquito nets over children’s beds in such areas.
被蚊子叮人后有可能把一种可能引起疟疾的寄生虫传染给(被叮的)人，在疟疾流行的地区，在儿童床上使用的蚊帐可以非常显著地降低由于蚊子被传染上疟疾的可能性。但是公众卫生官员却不太建议这样做。
Which of the following, if true, would provide the strongest grounds for the public health officials’ reluctance?
Early exposure to malaria increases the body’s resistance to it and results in a lesser likelihood of severe life-threatening episodes of malaria. 如果在幼年时期就接触了疟疾病菌有助于产生抗体，并减少了以后得可能危及生命的疟疾的可能性。正确。
Mosquito bites can transmit to people diseases other than malaria.除了传染A病，还可以传染B病，那不是更该用蚊帐吗?
Mosquito nets provide protection from some insect pests other than mosquitoes. 同B。
Although there are vaccines available for many childhood diseases, no vaccine has been developed that is effective against malaria.同B。
The pesticides that are most effective against mosquitoes in regions where malaria is common have significant detrimental effects on human health. 那看来用蚊帐是更安全的措施，那为什么不用呢?这个选项没有回答这个问题。
GWD-9-Q13:
Fact: Asthma, a bronchial condition, is much less common ailment than hay fever, an allergic inflammation of the nasal passages.
Fact: over 95 percent of people who have asthma also suffer from hay fever.
事实一：气喘这种支气管病症比花粉过敏性的鼻炎症更少见。
事实二：超过95%的得了气喘病的人同样也有花粉过敏症。
列数式如下：得气喘病的人数为X， 得花粉过敏症的人数为Y，其中0.95X 也属于 Y中的一部分，同时X
If the information given as facts above is true, which of the following must also be true?
Hay fever is a prerequisite for the development of asthma 没有事实可以推出两个病之间有结果关系，只知道两个病之前有并集出现。
Asthma is a prerequisite for the development of hay fever 同A。
Those who have neither hay fever nor asthma comprise less than 5 percent of the total population 题中的95%是指已经得了气喘病的人数的95%，所以推不出全部人口。
The number of people who have both of these ailments is greater than the number of people who have only one of them 从上面的数式可以推出得了两个病的大于只得了X的，但是由于X小于Y，所以不知道X的95%占Y中的百分比。
The percentage of people suffering from hay fever who also have asthma is lower than 95 percent. 因为Y大于X，所以Y的95%必然大于X的95%。正确。
GWD-9-Q14:
The Eurasian ruffe, a fish species inadvertently introduced into North America’s Great Lakes in recent years, feeds on the eggs of lake whitefish, a native species, thus threatening the lakes’ natural ecosystem. To help track the ruffe’s spread, government agencies have produced wallet-sized cards about the ruffe. The cards contain pictures of the ruffe and explain the danger they pose; the cards also request anglers to report any ruffe they catch.
叫R的这种鱼是近年无意中引进到北美的GREAT LAKE来的，这种鱼以食湖白鱼(一种当地品种)的卵为生，由此严重的威胁了湖的生态系统。为了追踪R鱼的散布情况，当地政府做了皮包大小的卡片，卡片的内容包括R鱼的图片和R鱼所引起的危害，并要求钓鱼者在钓到R鱼后通知有关部门。
Which of the following, if true, would provide most support for the prediction that the agencies’ action will have its intended effect?
The ruffe has spiny fins that make it unattractive as prey. 没有涉及人们会去配合政府部门要求的解释，无关。
Ruffe generally feed at night, but most recreational fishing on the Great Lakes is done during daytime hours.白天不容易钓到怎么办?这个选项好象是想让你觉得因为有了卡片钓鱼者就会白天去钓。明显就是专门为想太多者设计的陷井选项。
Most people who fish recreationally on the Great Lakes are interested in the preservation of the lake whitefish because it is a highly prized game fish. 就是说大家为什么就要钓这鱼并且在钓了这鱼后为什么会去麻烦自己去跑到政府部门呢，就是因为如果R鱼这个问题不解决，会直接影响到钓鱼者的切身利益。正确。
The ruffe is one of several nonnative species in the Great Lakes whose existence threatens the survival of lake whitefish populations there.是不是唯一的不是讨论的话题，题目要求的是找出一个答案来支持人们看了卡片后，钓到R鱼后，会去给政府打招呼。
The bait that most people use when fishing for whitefish on the Great Lakes is not attractive to ruffe. 就是说如果不看卡片，人们可能就不换铒，但是即使换了铒钓到R鱼后，仍没有事实让我们相信人们会去给政府部分报告钓到R鱼这件事。
GWD-9-Q16:
A diet high in saturated fats increases a person’s risk of developing heart disease. Regular consumption of red wine reduces that risk. Per-capita consumption of saturated fats is currently about the same in France as in the United States, but there is less heart disease there than in the United States because consumption of red wine is higher in France. The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.
一种的饮食会增加得心脏病的危险。经常性的喝红葡萄酒会降低这种风险。法国和美国的这种高脂肪食物的人均消耗量是差不多一样的，但是法国人比美国人更少得心脏病，其中原因就在于法国人均的红葡萄饮用量高于美国人。但是这两个国家的红葡萄酒人均饮用量的差别正在逐渐减小，不过并没有相应的心脏病发病率的相应变化出现。
Which of the following, if true, most helps to account for the lack of convergence noted above?
Consumption of saturated fats is related more strongly to the growth of fatty deposits on artery walls, which reduce blood flow to the heart, than it is to heart disease directly. 不管这个含高脂的食物构成是引发心脏病的直接还是间接原因，反正都是一个原因。要回答的问题也不是说引发心脏病的原因是什么，而是为什么喝了葡萄酒心脏病发病的人并没有减少。
Over the past 30 years, per-capita consumption of saturated fats has remained essentially unchanged in the United States but has increased somewhat in France.那为什么法国人没有更多的人得心脏病而美国人没有更少的人得心脏病呢?
Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly. 同B
Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than in the United States.并没有告诉我们法国人因为这个就得心脏病的人多了，而且这个轻微的量词也不足以推出这个结论。
Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age. 因为法国人年青人的红酒饮用量大幅度减少(所以他们中得心脏病的人数会多，)，但是心脏病通常在中年后发作，所以现在还看不出来。正确。
