Day 119
1. 认真的修理厂
A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company’s warranty. The reworked jobs are invariably satisfactory. When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.
The argument above assumes which of the following?
A. There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
B. There is no company that successfully competes with Ace Repairs for complex repair jobs.
C. Ace Repairs' warranty is good on first-time jobs but does not cover rework jobs.
D. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.
E. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

2. 鱼、猪肉和移民
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.

3. 生物制油
某 plantation 种植园有大量 soybean，可以制成燃料给拖拉机？用，但是成本很高，做一桶这种生物燃料的成本都可以买 2 桶汽油了，但是这里的人还是在这么做，为什么？
