GWD-9-Q38:
In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.
去年一月以后，M连锁电影院开始用更健康的Canola油取代了之前一直使用的椰子油来制作爆米花。现在M公司准备再重新开始使用椰子油，因为M公司认为就是因为使用了canola油而影响了爆米花的销售。但这个结论是错的，因为根据M公司自己的销售数据，M去年比前年销售的爆米花增加了5%。
Which of the following, if true, most strongly supports the argument against Moviemania’s claim?
Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year. 去年M影院的零食销售增加了不到5%，在这种情况下爆米花销售增加了5%。正确。
Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets. 题目中比的是爆米花不期的销售对比，而不涉及零食销售和电影票销售的对比。
Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil. 喜欢是一回事，买没有买是另一回事，喜欢的人有多少，其中又有多少人买了，这些条件没给，所以此项无关。
Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.看电影的人增加了百分之二十，而爆米花的销售只增加了百分之五，不能说是好成绩，明显是唱反调的先项。
The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year. 前年，M公司销售的爆米花比它上前年增加了百分之十，但不能因为这个就说每年都必须增加百分之十，因为基数不一样了。
GWD-9-Q40:
Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods. All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.
农业社会如果没有主食农作物就不会存在。西非有几种已知的食物农作物，比如K和O，但是这些都不是主食。所有有记录的在西非种植的主食(稻米和甜薯)全是进口的，但是进口的时间不能确定。因此，如果能确定西非进口稻米和甜薯的时间就要以断定西非最早成为农业社会的时间。
Which of the following is an assumption on which the argument depends?
People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced. 西非人在进口稻米和甜薯之前没有种植其它的主食，而在进口之后就停止了本土主食的种植。如果他们在进口之前已经有主食农作物的话，那西非成为农业社会的时间就早于进口稻米和甜薯的时间，那么即使能确定进口时间也没法确定西非成为的农业社会的时间。正确。
There are no plants native to western Africa that, if domesticated, could serve as staple food crops.即使现在有，但没有提供信息让我们知道这些crop是在进口稻米和甜薯之前还是之后出现的，如果是之前是加强，如果是之后是无关。既然两种可能都有，就只有当错误选项处理。(对于这个选项的否定应该有更好的解释才对)
Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa.只在谈西非，其它地区无关。
Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are. 只在谈主食农作物，其它农作物无关。
Kola and okra were domesticated in western Africa before rice and yams were introduced there. 同D。
