九山环一湖

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.

Which of the following, if true, most helps to explain the increase?

1. Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays.
   



2. 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.
   



3. The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn.
   



4. 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.
   



5. 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.

偶选B。

     原文推理：R地新开了M餐饮店——》W餐饮店生意会降低

            结论：M店开张以后，W店每晚的就餐数量大大增加

     问解释

     A，D，E无关

     我选B，B说M店就餐的人在M店开张之前大多都没在R地吃过饭（说明M的开张增加了总的吃饭人数），而且M店总是有人抢不到位置吃饭（说明增加人数有部分没吃到饭）——》只好到W店去吃了

     C我差点选了，选之前反思了一下，这个选项还是无关的。选C的可能的理解是：因为M店利润高——》M店食物贵——》人去W店吃

     但是这个推理是不严密的，因为M店利润高——》M店食物贵，原文没有这种信息暗示

注意原文的"only",  从这个only可以推出-->>要么在M要么在W. 既然客源增多，M又take不了那么的客人，剩下的客人正好解释了W客源的上升。所以，B可以解释。

但C就不行了，利润高不一定推出价格就高，很多其他的原因比如：人工成本低，材料成本低。。。都可以产生高利润。想想咱们国家是靠什么成为输出大国的的 ：）

b is right

blur的解释让偶豁然开朗,谢谢!

以下是引用yuli5在2004-10-6 21:00:00的发言：
B说M店就餐的人在M店开张之前大多都没在R地吃过饭（说明M的开张增加了总的吃饭人数），而且M店总是有人抢不到位置吃饭（说明增加人数有部分没吃到饭）－－》只好到W店去吃了，有人抢不到位置吃饭并不表明只好到W店去吃，可以回家或go to neighboring towns to eat.这个推理就象因为M店利润高－－》M店食物贵一样不严密，请解释一下。

我想，大概是解释题只要解释到原因就算数了吧~?没得吃可回家吃，或不吃，或排队，或去W吃。可能是解释到"有机会去W吃"就算合理。

我只能这么想，因为我跟你有相同的困惑。所以用消去法选了B。

至于C，就算你说的那个不严谨的推理成立，没有理由说W会增加顾客啊，因为那个推理顶多说明顾客会选W不选R，因此只说明了W不会下降，但不能说一定增加。

如同上几楼所说的，B比C多表达了"客源总量增加"。如果把B的第一句话加进C中，这样C才有机会成立。

嗯，看到B中的profit偶就排除啦，因为只有人数是相关的

文中说number of meals per night…

anyway,profit跟人数关系不如Ａ解释得好

权衡一下，还是选B
