78 The country of Baurisia has, until now, been self-sufficient in both grain and meat.  However, with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat.  Therefore, since per capita income in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely, Baurisia is soon likely to become an importer of grain.

Which of the following, if true, most seriously weakens the argument?

A. When people increase their consumption of meat, they also tend to increase their consumption of grain.

B. The per capita consumption of meat in Baurisia is roughly the same across all income levels.

C. Per capita consumption of meat has not increased substantially in recent years in those countries from which Baurisia is likely to import meat.

D. It is more economical for Baurisians to import meat than grain.

E. During Baurisia's years of growing prosperity, the country's population has remained relatively stable.

Advertisement:  Ten years ago, the Cormond Hotel's lobby was carpeted 铺地毯with Duratex carpet while the lobby of a nearby hotel was being carpeted with our competitor's most durable carpet.  Today, after a decade in which the two hotels have had similar amounts of foot traffic through their lobbies, that other hotel is having to replace the worn-out carpeting near its lobby entrances, whereas the Cormond's Duratex carpeting has years of wear left in it.

Which of the following, if true, most seriously weakens the force of the advertisement's evidence for concluding that Duratex carpet is more durable than the carpet of its competitor?

A. The lobby of the Cormond Hotel has five different entrances, but the lobby of the other hotel has only two.

原题说 since if the products disappoint consumers, the magazine's reputation suffers, with consequent reductions in circulation and advertising

又说However, experts have evaluated the cookware and found it superior to all other cookware advertised in Kitchen.这句就把reductions in circulation 排除掉了

而C又把reduction in advertising排除掉了，所以选C

73 广告是说 10年间,C Hotel大厅使的D牌地毯依然完好并且还有几年使用期, nearby Hotel使的D牌竞争者地毯(铺在大厅入口处的)已然烂了, 人流量两家差不多 ,所以D牌地毯好。
选A因为设人流量都是100, D牌被踩100/5=20次 而 competitor的被踩100/2=50次， 从而不能推出D好
