GWD #5 #8 Help Thanks

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.

Please help me expain this question. Thanks! The solution is b.

这是一个因果关系的命题。

但是effect can not be derived from the cause.那么肯定是他因了。

A。这道题目注明了是average meals per night所以跟是weekdays还是weekends没关系

B 是一个他因： martin带来了很多新的客源，所以没有威胁到wildflower的生意，反而因为新的客源太多，很多客人只有跑到wildflower去吃饭。 很好的解释了这个increase.

C profit在原文中根本没有提到，无关

D 这样的话wildflower 的客人应该减少才对。

E staff没有提到，无关

Thanks a lot

It makes sense to me.
