再问GWD5-Q8

GWD5-Q8:

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?

 

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

B.       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.

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

D.      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.

E.       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.

ans: B, I choose C, totally lost...

没有人理吗？。。。

在Martin没开之前大多数人从来都不出去就餐，Martin开了之后，很多人都出去就餐了，但是由于Martin很多天人都满了，所以那些人只有去Wildflower Inn了，因此Wildflower Inn的the average number of meals per night served 提高了

C 选项,M餐厅赚的PROFIT高, 不一定就是价钱高, PROFIT跟价钱无关的.

而B选项, 因为M餐厅根本就没位置了给你坐下来吃饭了, 那客人还不如去W那里吃饭, 这样就是提供了一个机会给W餐厅, 比较合理.

Martin’s Cafe在Riverville开店以前，cafe的customer（可能都在别的地方的martin's cafe吃）是不会来riverville的。在riverville开了店后，这些原本cafe的customer才来riverville，又因为在cafe里没位置坐，所以去了Wildflower 。也就是说wildfower实际上因为cafe而得到了一些原先根本不来riverville的客户，因此the number of customers increase了。
c是个无关选项，gmat最喜欢在你推不出来的时候给你一个让你认为是有点common sense的选项。但题目中根本没有涉及到profit, 而c中的profit跟the number of customers 没有直接联系。

GWD5-Q8:
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.
【
“因果推理”
因：Martin’s Café opened
果：Wildflower Inn meals increased
CQ1  因果概况问题（一因有多果，或者因果没有联系）
CQ2 干扰因素（原文前提+选项≠结论）
Martin’s Café opened (logical gap)  wildflower Inn meals increased
】
Which of the following, if true, most helps to explain the increase?
A.        Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays. （跟weekend 和weekday的区别没关系，而且无法解释WI的meal为啥增加）
B.        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. （这里涉及到了MC这个“因”的特点，解释了CQ1因果联系，说明为啥WI increase）
C.        The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn. （我们是在讨论average number of meal 的问题，不是在讨论profit per meal的问题）
D.        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. （如果在MC吃，反而是削弱选项）
E.        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. （跟员工没直接关系，也没有涉及到“因”的特点）


profit= revenue-cost

［关于B、C项的一点个人理解]

BACKGROUND: at R, M open---> threaten to W (the only restaurant at R)   (M开业--->影响当地唯一一家饭店w的生意）
FINDING: avg meal/ night at w INCRESE significantly（ 要解释的现象）－－》本题核心

Choice B
B.   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.

point 1:吸引了许多从M 没开业之前从未来R吃过饭的人-->扩大了客源
point2: 客人数量多到在M坐不下--->M新吸引的客人＝从未到R吃过饭的客人（most)＋其他在R吃过饭的客人---->坐不下---->不会影响去W店的客人数,至少不会大幅减少
point3: Before M opened,W is the only restaurant---->暗示了如果总客流量既定，去不了M就会去M

Given the information provided above,
I will choose B.
我不认为如果m坐不下没得吃，会导致那些没得吃的客户回家或者去其他城市吃，因为基于题目已经给出 the only，是提示性信息。如果非要提出其他可能，是为了证明B有漏洞而过于牵强。

Choice C
至于c项，错误相当明显，profit per meal 与 avg meal/ night 没有直接相关，meal price= cost+profit
假设： M的profit per meal 是5，cost是5，meal price＝10
          W的profit per meal 是3，cost是8，meal price＝11，
         那作为消费者，我会选择M 而不是W的，因为顾客本身只会看到价格，无法知道利润和成本。

究其本质来说，C是无关选项。
avg meal/ night 的上涨，只与吃饭的人数 和 nights opening有关。

以上。
