CR 大全 test 18 Q 13
13. Canadians now increasingly engage in “out-shopping,” which is shopping across the national border, where prices are lower. Prices are lower outside of Canada in large part because the goods-and-services tax that pays for Canadian social services is not applied.
Which one of the following is best supported on the basis of the information above?
(A) If the upward trend in out-shopping continues at a significant level and the amounts paid by the government for Canadian social services are maintained, the Canadian goods-and-services tax will be assessed at a higher rate.
(B) If Canada imposes a substantial tariff on the goods bought across the border, a reciprocal tariff on cross-border shopping in the other direction will be imposed, thereby harming Canadian businesses.
(C) The amounts the Canadian government pays out to those who provide social services to Canadians are increasing.
(D) The same brands of goods are available to Canadian shoppers across the border as are available in Canada.
(E) Out-shopping purchases are subject to Canadian taxes when the purchaser crosses the border to bring them into Canada.
Ans : A
is not applied指没实施还是不适合??

Og 173 看不懂它的逻辑关系,可指点思路?
6. Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged. They will thus burn significantly fewer calories at the new weight than do people whose weight is normally at that level. Such newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic rate.The conclusion of the argument above depends on which of the following assumptions?
(A) Relatively few very overweight people who have dieted down to a new weight tend to continue to consume substantially fewer calories than do people whose normal weight is at that level.
(B) The metabolisms of people who are usually not overweight are much more able to vary than the metabolisms of people who have been very overweight.
(C) The amount of calories that a person usually burns in a day is determined more by the amount that is consumed that day than by the current weight of the individual.
(D) Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.
(E) Because of the constancy of their metabolic rates, people who are at their usual weight normally have as much difficulty gaining weight as they do losing it.

Ans: a

is not applied指没实施.
题目是说,人们去外地买便宜货.而外地货之所以便宜,是因为不需额外课税用以支持 social services .
论点为：人们去外地买货，便宜货→不用课税→不用支付social services. 问支持.
a) 用举例说明支持了这个论点. 假设越来越多人去买外地货，而social services的费用仍旧维持一定，则课税会增加。

(OG173)

问Assumption则可以利用取非来检验。

Evidence为：超重的人相对而言新陈代谢率低(导致脂肪囤积)，当他们藉由节食来减肥，他们的新陈代谢率并不会改变。即使他们减重成功，相较那些同体重的人，减重成功的人仍旧消耗较少的calories。

Conclusion为：新陈代谢维持不变，则减重成功的人们会慢慢复胖，直到体型和低新陈代谢率相互match.

A)relatively few very overweight people who have dieted down to a new weight tend to continue to consume substantially fewer calories than do people whose normal weight is at that level.

A选项取非验证，亦即，很多超重的人在减重成功之后，会持续节食，消耗较少的calories.→所以他们不会复胖，与conclusion矛盾→亦即，若选项A不存在，则此conclusion也不存在，所以选项A为此题的必要assumption.

太棒了light版主 ,分析细腻仔细,思路清楚易懂,比我自己牵强乱解强太多了,感谢感谢!!

有点小错误, 消耗较少的calories, ----->应该是消耗更多的calories 吧

不过, light还是很棒的.

我来试着翻译一下选项A：相比较而言，很少有节食减至新体重的超重者比这个水平上的正常体重者倾向于继续消费更少的calories.

累死我了
