Q2: GWD-4-14
Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.
旅游指南书作者：我去过这个国家的各地的饭店，经我观察，那些在1930年前修的饭店里的木工活质量总体上来讲质要比在那之后修的饭店的高。所以1930前的木工要比以后的更有技巧、更仔细并且也更肯下功夫。
Which of the following, if true, most seriously weakens the guidebook writer’s argument?
The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.要比的是1930前的饭店木工和1930年后的饭店木工，拿其它的来比明显就是错误选项。
Hotels built since 1930 can generally accommodate more guests than those built before 1930.这句话的目的就是要想让你联想过多，比如说因为客人多所以磨损的就多。但这是陷进喔，人多会不会就造成磨损多要由题干来讲，而不是让你来帮它想。所以不对。
The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.如果用材没什么不一样，那就是说用材的人不一样了。这个是帮指南书在说话而不是在给他唱反调，但题目要求我们的是唱反调。
The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. 也就是说，质量好的才可能到今天你这个写书的也都可以visited，质量不好的早就没影了。相当于你拿一班的尖子生来和二班的留级生比，这样比让人生气不说，你还要加一句，我们大家都可以清楚地看到：一班的学生普遍成绩要比二班的普遍成绩好很多。正确。
The average length of apprenticeship for carpenters has declined significantly since 1930. 同C，战线没站对。
Q3:
The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.
事实一：V国的电视机组装工人的平均小时工资要比邻国B国的低很多(V
事实二：B国在三年前将从V国进口电视机的关税降低了。
事实三：B国每年电视销售量并没有变化。
事实四：B国的电视组装工作数减少了。
结论：从V国进口的电视机数量是增加了。
Which of the following is an assumption on which the argument depends?
The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased. V国增加的组装电视机数量=B国降低的电视机数量。题中没有告诉你V国增加了组装量，完全有可能它在保持甚至减少了生产量的情况下增加了对B国的出口。所以A选项中的情况不是必须出现的。
Televisions assembled in Vernland have features that televisions assembled in Borodia do not have. V国组装的电视有没有新功能不是问题，题干告诉我们两国电视组装的区别是人工成本。
The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.B国在过去三年里每个组装工人组装电视的平均时间并没有减少。如果以前需要五个小时装一个电视，现在需要一个小时，那么也就是说，现在一个人可以干以前五个人的活，那人数降低有可能产量并没有影响。而我们要确定的就是在B国的电视销售量没有变化的情况下，B国的本国电视机生产量减少了，那么明显就是从其它国家买了更多的电视。正确。
The number of televisions assembled annually in Vernland has increased significantly during the past three years.V国装电视装的再多也不能断定多出来的就是销往B国了，有可能在本国就卖完了，也可能出口到别国了。
The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.在未来几年工资的变化也可能会对B国现在的电视进口状况有所影响，但这个影响显然不可能发生在现在，所以是无关选项。
Q8:
When a new restaurant, Martin’s Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville’s only other restaurant, would suffer from the competition. Surprisingly, however, in the year since Martin’s Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.
去年R地新开了一个M咖啡馆。之前此地只有一间餐厅W，当时很多人预言W的生意会因为新的竞争者而变得不好。奇怪的是自从新咖啡馆开业后，W餐厅的每晚平均顾客反而比以前多了很多。
Which of the following, if true, most helps to explain the increase?
Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays. M周末的菜式比平日的多并不能解释为什么W的生意比以前好。最多能说两个餐厅的经营风格不一样有可能造成顾客分流。
Most of the customers of Martin’s Cafe had never dined in Riverville before this restaurant opened, and on most days Martin’s Cafe attracts more customers than it can seat.换句话说本来要去M吃饭的人只能去W吃。正确。
The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn.利润的高低不在此题的讨论范围。
The Wildflower Inn is not open on Sundays, and therefore Riverville residents who choose to dine out on that day must either eat at Martin’s Cafe or go to neighboring towns to eat. 不能解释为什么W的生意为什么变好，反而可以推说它的生意可能不好。
A significant proportion of the staff at Martin’s Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin’s Cafe.M把W的人挖墙角挖走了应该是影响W的生意。
Q13:
It is true of both men and women that those who marry as young adults live longer than those who never marry. This dose not show that marriage causes people to live longer, since, as compared with other people of the same age, young adults who are about to get married have fewer of the unhealthy habits that can cause a person to have a shorter life, most notably smoking and immoderate drinking of alcohol.
年轻的时候就结婚了的比从未结婚的活得长。但是并不是结婚这件事让人们活得长，和同齡人比较，在年轻的时候就结婚的人有较少的影响长寿的不良习惯，最显著的就是抽烟和酗酒。
Which of the following, if true, most strengthens the argument above?
Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm. 题干中提到了长寿和生活的不良习惯，答案就必然和两个有关。而这个答案里面有身体伤害，有不坚持日常锻炼，但是没有我们需要的两项。
A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried. 题干说的是没有不良习惯而不是以前有，后来没有。题干说的是没有不良习惯本身让人长寿，而不是婚姻让人放弃不良习惯从而让人长寿。
A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately. 这个答案简而言之就是什么样的人找什么样的老婆，但是题干关注的不是什么类型的夫妇才长寿，而是年轻的时候结婚的长寿，长寿的原因在于结婚得太早以至于没有机会染上不良习惯。和这个答案完全讨论的是两回事。
Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.同B
Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry. 和题干一样，表明正是不抽烟和不酗酒让人长寿。正确。
Q15:
Lightbox, Inc., owns almost all of the movie theaters in Washington County and has announced plans to double the number of movie screens it has in the county within five years. Yet attendance at Lightbox’s theaters is only just large enough for profitability now and the county’s population is not expected to increase over the next ten years. Clearly, therefore, if there is indeed no increase in population, Lightbox’s new screens are unlikely to prove profitable.
一个拥有W国家几乎全部剧场的L公司最近宣布在五年内把映画放映幕数量翻倍。尽管现在的观众数量刚好够让L公司有利润，而且在未来十处，W国家的人口也不太会增加。所以，既然人口不增长，L公司的这项举措就不太可能帮它赚钱。
Which of the following, if true about Washington County, most seriously weakens the argument?
Though little change in the size of the population is expected, a pronounced shift toward a younger, more affluent, and more entertainment-oriented population is expected to occur.尽管人口不增长，但说明这个公司的消费者会增加。正确。
The sales of snacks and drinks in its movie theaters account for more of Lightbox’s profits than ticket sales do. 卖零食比卖票更嫌钱。但是如果来的人不增多，也就不可能更赚钱。
In selecting the mix of movies shown at its theaters, Lightbox’s policy is to avoid those that appeal to only a small segment of the moviegoing population. 仍然没有说明人口的问题。
Spending on video purchases, as well as spending on video rentals, is currently no longer increasing. 其它行业的经营情况不是讨论的话题，讨论的是现在的顾客不足以让成倍的放映点保持赚钱。所以一般说来凡是没有涉及到人口的答案都不是正确答案。
There are no population centers in the county that are not already served by at least one of the movie theaters that Lightbox owns and operates.就是说肯定赚不了钱，当然是错误选项。
