做题做到脑袋实在转不过来弯，谁来帮帮我

1. 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. 答案

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.

觉得解释的优点牵强，为什么C 不对呢？

 

2. In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy domestic demand.  Teruvia’s total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably.  Teruvia’s population, however, will be increasing significantly for years to come.  Clearly, therefore, Teruvia will soon have to begin importing rice.

 

Which of the following is an assumption on which the argument depends?

 

A.      No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia. 答案

B.       Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.

C.      None of the strains of rice grown in Teruvia are exceptionally high-yielding.

D.      There are no populated regions in Teruvia in which the population will not increase.

E.       There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

E为什么不对？？？

From 1980 to 1989, total consumption of fish in the country of Jurania increased by 4.5 percent, and total consumption of poultry products there increased by 9.0 percent.  During the same period, the population of Jurania increased by 6 percent, in part due to immigration to Jurania from other countries in the region.

 

If the statements above are true, which of the following must also be true on the basis of them?

 

A.      During the 1980’s in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish.

B.       For people who immigrated to Jurania during the 1980’s, fish was less likely to be a major part of their diet than was poultry.

C.      In 1989 Juranians consumed twice as much poultry as fish.

D.      For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.

E.       Per capita consumption of fish in Jurania was lower in 1989 than in 1980.答案

谢谢大家

第一题，the average number of meal increase没办法通过profit per meal大小的比较来解释。利润率的大小只能说明Martin's的价格较高or成本较低，而销售量的大小主要取决于产品对客户的吸引力。所以跟吸引力有关的只有B

第二题，E里面提到major crops other than rice，属于跟rice无关的信息，Irrelevant information.

第三题，B说在移民当中，消费poultry比fish多。而原题是说两者都在增加，而增加的部分究竟大部分被原著民消耗了还是新移民消耗了？文中并无说明。如果家禽增加的消费量大多被原著民消费了，这就weaken了B选项了。所以是E

明白了～～～～～谢谢：）

文科生的逻辑真的无药可救了么

文科生怎么了，我也是文科生，楼主不要觉得自己是文科生逻辑就一定不行。如果你是才开始做题，思路不清楚很正常的，花点时间就好了。等题做到一定量的时候，你就会发觉其实逻辑是Verbal里最好做的部分。
