标题: 关于CR feifei logic又来求助啦~~~
题目如下~~
Questions 5-6
Sales manager: Last year the total number of meals sold in our company restaurants was much higher than it was the year before. Obviously consumers find our meals desirable.
Accountant: If you look at individual restaurants, however, you find that the number of meals sold actually decreased substantially at every one of our restaurants that was in operation both last year and the year before. The desirability of our meals to consumers has clearly decreased, given that this group of restaurants---the only ones for which we have sales figures that permit a comparison between last year and the year before---demonstrates a trend toward fewer sales.
5. If the sales figures cited by the accountant and the sales manager are both accurate, which one of the following must be true?
(A) The company opened at least one new restaurant in the last two years.
(B) The company’s meals are less competitive than they once were.
(C) The quality of the company’s meals has not improved over the last two years.
(D) The prices of the company’s meals have changed over the past two years.
(E) The market share captured by the company’s restaurants fell last year.
这题为什么不选D呢,A也能讲通,but why not D?
6. Which one of the following, if true, most seriously calls into question the accountant’s argument?
(A) The company’s restaurants last year dropped from their menus most of the new dishes that had been introduced the year before.
(B) Prior to last year there was an overall downward trend in the company’s sales.
(C) Those of the company’s restaurants that did increase their sales last year did not offer large discounts on prices to attract customers.
(D) Sales of the company’s most expensive meal contributed little to the overall two-year sales increase.
(E) Most of the company’s restaurants that were in operation throughout both last year and the year before are located in areas where residents experienced a severe overall decline in income last year.

5. E,你不知道price的变化方向是什么。

补充A:
“Both accurate“,还是explain the situation/resolve the paradox。
经理:去年所有餐厅卖出的meal总数比之前多。
会计:去年每一家卖的meal其实都比之前卖的变少了。
Commonsense可以推测出,去年的餐厅数量肯定比之前的餐厅数量多。
比如:
去年10家餐厅,每家卖了10meal,总数是10*10=100。
之前X家餐厅,每家卖了11meal,总数是11X
根据两人说的话,100>11X,即X最大为9,也就是至少新开了1家餐厅。

6. “已知现象,回溯原因”的推理,如侦探查案。
几乎所有的现象解释题都是果因推理(结论是解释)。

会计的conclusion:“The desirability of our meals to consumers has clearly decreased”,我的目标就是说“每一家卖的少,不能说明desirability has decreased”。
预想:其他原因导致的卖的少;果因之间没有关系。
