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.

答案是A。我不明白原文哪里可以推出新开restaurant啊。恳请大家指点。

经理说：销售总量增加了，可以看出顾客更喜欢咱们的菜；

会计说：但每一个今年和去年已经营业的餐馆销售确在下降（后面不看也行）。

接下来就是算术题了，总量增加，营业2年以上的销售量减少，总量肯定大于2年餐馆销售量，差额就是两年内开业餐馆的销售量，也就是说总量增加并不是原有餐馆的销售量增加，而是开了新餐馆。

得出A
