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.
-A，结论返工的更认真，那达成结论需要排除其他差异因素，比如负责返工的都是高级工，初次的是实习生

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.
-E

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？
-处理废弃soybean的成本更高/汽油油价比这个新的低，但是运到园里运费太高/对于拖拉机而言新燃料燃烧效率是汽油2倍以上

1. 都要二次返工—不是因为技术问题—而是因为会更加注意力集中
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.
2.B ❌ D
3.p：soybean油贵
c：但人们还是要用
问原因
1.其他优点，比如耐用或者环保
2.支持成本这个点：生产成本不等于运输成本

E. There is no category of repair jobs in which Ace Repairs invariably carriesout first-time jobs satisfactorily.

F：一部分由ace修理工担当负责修理的工作需要返工，返工的工作让人满意。

P：？

C：开始的工作完成得不好不是因为这些人没有胜任的能力，而是因为这个复杂的修理工作返工的时候比第一次工作时能有更高的注意力

Q：问假设

思路：找gap

选项：A，返工的人跟第一次做的人并无系统性差别，说明两群人具有一样的能力，从而能推出结论，对；B，无关；C，无关；D，与有无补贴无关；E，没有哪类工作总是能让人第一次满意，无关；

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

F：1980-1989年，鱼消耗量增长4.5%，猪肉消耗量增长9%，J地人口增长6%，有一部分是因为他国的人口迁移

P：？

C：？

Q：问结论

思路：根据已有信息推论

选项：A，只是知道消耗量又不知道价格与成本，无法推知产品的利润；B，无法推出；C，只是消耗量增长，未知原本消耗量无法推知倍数关系；D，无关；E，对，鱼的消耗量增长率比不上人口增长率，4.5<6；

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？

F：种植园有好多大豆，可以当燃料给拖拉机用，但成本很高

P：？

C：这里的人仍然在用大豆炼油

Q：问原因

思路：找大豆的优点或者种植园一些不得不做的理由

方向：大豆炼油过程中产生的副产品卖价高，能让种植园获利；大豆炼的油使用效率高，耐用，所以卖家高，依然能让种植园有利可图；大豆没有其他能获利的销路，种植园只能炼油赚取一些成本费用。
