202.Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.

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

(A) The total acreage devoted to grain production in Gortland will not decrease substantially.

(B) The population of Gortland has remained relatively constant during the country’s years of growing prosperity.

(C) The per capita consumption of meat in Gortland is roughly the same across all income levels.

(D) In Gortland, neither meat nor grain is subject to government price controls. E

(E) People in Gortland who increase their consumption of meat will not radically decrea se their consumption of grain.

谢谢指教，很有收获。我看到很多NN们都说assumption是模式最固定，比较好掌握的一个题型，可是我在assumption上却总也找不到感觉。也看了一些大家对排出他因和gap的分类（题目的划分），却发现有的甚至和og的解释不一样，感觉很困惑...有的题目有人列为他因，有人列为gap...

例如

8. To prevent some conflicts of interest, Congress could prohibit high-level government officials from accepting positions as lobbyists for three years after such officials leave government service. One such official concluded, however, that such a prohibition would be unfortunate because it would prevent high-level government officials from earning a livelihood for three years.

 

 

The official’s conclusion logically depends on which of the following assumptions?

A. Laws should not restrict the behavior of former government officials.

B. Lobbyists are typically people who have previously been high-level government officials.

C. Low-level government officials do not often become lobbyists when they leave government service.

D. High-level government officials who leave government service are capable of earning a livelihood only as lobbyists. D

E. High-level government officials who leave government service are currently permitted to act as lobbyists for only three years.

还有有的题目不知道是他因还是gap，如

 

 

76. A famous singer recently won a lawsuit against an advertising firm for using another singer in a commercial to evoke the famous singer’s well-known rendition of a certain song. As a result of the lawsuit, advertising firms will stop using imitators in commercials. Therefore, advertising costs will rise, since famous singers’ services cost more than those of their imitators.

 

 

The conclusion above is based on which of the following assumptions?

(A) Most people are unable to distinguish a famous singer’s rendition of a song from a good imitator’s rendition of the same song.

(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.

(C) The original versions of some well-known songs are unavailable for use in commercials.

(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers. E

(E) The advertising industry will use well-known renditions of songs in commercials.

 

再次请教，不胜感激.....

看了楼上的分析，我就会有些明白，但是一到自己做的时候，很多地方就又很糊涂。我个人认为，反复分类做og是个解决的办法，不知道您认为如何？或者还有什么更好的建议？谢谢!
