逻辑第8套：
8.1Auditor from Acme Industries: Last week at Acme Bakery, about six percent of the pastries baked during the night shift were found to be imperfect, but no imperfect pastries were found among those baked during the day shift. Pastries are inspected during the same shift in which they are baked, so clearly the night-shift quality control inspectors were more alert, despite their nighttime work hours, than the dayshift quality control inspectors.
The argument depends on the assumption that：
(A) at least some imperfect pastries were baked during the day shift at Acme Bakery last week
(B) not all of the pastries that the night-shift quality control inspectors judged to be imperfect were in fact imperfect
(C) the night-shift quality control inspectors received more training in quality control procedures than did the day-shift quality control inspectors
(D) in a normal week, fewer than six percent of the pastries baked during the night shift at Acme Bakery are found to be imperfect
(E) there are only two shifts per day at Acme Bakery, a day shift and a night shift
我选B，答案A。我认为文章为了强调加强监测夜班查出残缺率，支持的应该是由于夜班检测的正确率存在争议吧。A说白天存在残缺却没有检查出来，和加强夜班检测力度有咩关系？费解。求指教！

8.6 When amphibians first appeared on Earth millions of years ago, the amount of ultraviolet radiation penetrating Earth’s atmosphere was much greater
than it is today. Therefore, current dramatic decreases in amphibian populations cannot be the result of recent increases in ultraviolet radiation penetrating Earth’s atmosphere.
Which of the following is an assumption on which the argument depends?
(A) The eggs of modern amphibians are not significantly more vulnerable to ultraviolet radiation than the eggs of the first amphibians were.
(B) Modern amphibians are not as likely as the first amphibians were to live in habitats that shield them from ultraviolet radiation.
(C) Populations of modern amphibians are not able to adapt to changing levels of radiation as readily as populations of early amphibians were.
(D) The skin of amphibians is generally more sensitive to ultraviolet radiation than the skin of other animals is.
(E) The skin of amphibians is less sensitive to ultraviolet radiation than to other types of radiation.
我选E，答案A。A我认为是对的。但是E为啥错类？既然两栖动物对紫外线都不敏感了，那肯定不是紫外线的错~~很dependent的结论啊~求指正。

8.11 Legislator: We should not waste any more of the taxpayers’ money on the government’s job-creation program. The unemployment rate in this country has actually risen since the program was begun, so the program has clearly been a failure.
Which of the following is an assumption on which the legislator’s argument depends?
(A) The budget of the job-creation program has typically increased every year.
(B) The unemployment rate would not have risen even more than it has if the job-creation program had not been in existence.
(C) The unemployment rate is higher now than at any time before the inception of the job-creation program.
(D) If the job-creation program had been run more efficiently, it could have better served its purpose.
(E) Other government programs are no more effective in reducing unemployment than is the job-creation program.
选C，答案B。B是说这个项目不存在，失业率不会上升。和C，自项目启动始失业率达到最高，有咩区别不？求指教。

8.13No one can be licensed as an electrician in Parker County without first completing a certain course in electrical safety procedures. All students majoring in computer technology at Parker County Technical College must complete that course before graduating. Therefore, any of the college’s graduates in computer technology can be licensed as an electrician in Parker County.
The answer to which of the following would be most helpful in evaluating the argument?
(A) Is a college degree a requirement for being licensed as an electrician in Parker County?
(B) Do all students majoring in computer technology who complete the course in electrical safety procedures at Parker County Technical College eventually graduate?
(C) Is completion of a course in electrical safety procedures the only way a person licensed as an electrician in Parker County can have learned those procedures?
(D) Is a period of practical apprenticeship a requirement for becoming a licensed electrician in Parker County but not for graduating from the college in computer
technology?
(E) Do any of the students at Parker County Technical College who are not majoring in computer technology take the course in electrical safety procedures?
选B，答案D。这个完成课程和答案中的实习学徒经历有必然关联不？

逻辑为啥老出错？明明觉得蛮简单的题，真是摧毁自信心啊！

第一题，题目说晚上监测有6%的pastries存在问题，但白天监测都合格。结论是：晚上的inspectors比白天的inspectors更加警觉。潜在结论：白天的那群inspectors太水了，啥都检测不出来...
所以很明显答案是A，一定要假设白天确实生产出有缺陷的pastries才能证明白天的那群inspectors不怎么alert，只不过白天的那群水货inspectors没有检测出来而已，因此才能得出题目的结论：晚上的inspectors比白天的好。
个人愚见。

第二题，关于紫外线的对比，只能是时间上的对比：millions of years ago和现在的对比，但E选选项却是同类型射线的对比：less sensitive than to other types of radiation.这种横向对比不能作为结论的假设。如果E选项改为less than millions of years ago就对了。故E错。
个人愚见。

第三题，请注意题干“The unemployment rate in this country has actually risen since the program was begun”。说这个legislator觉得，实施的这个计划后的失业率事实上却上升了，所以这个计划很失败。很明显，legislator是从“失业率上升”推出结论“计划很失败”，所以跟失业率是否是最high没有关系。所以C要排除掉了。
个人愚见。

至于最后一题，这是典型的三段论啊
1.没有完成一个certain course的人不能拿到电气师执照
2.所有在PCT学院主修计算机的学生在毕业前都要完成这个course
3.故所有在PCT学院主修计算机的毕业生都能拿到电气师的执照。
但是我选的是E...选错了，桑心啊...所以这一题，本人还在揣摩中...LZ还是忽略我这条回复吧...

okqishi(ok橙)尊是给力啊！！看懂好几道！但是第二道还是不了解。紫外线的横向对比，它的语态代表了一直以来~~是一种常规的比较。也就是时间上的比较~~我认为也对啊~最后一道是一道神奇的题目！

你看看第二题的E选项“The skin of amphibians is less sensitive to ultraviolet radiation than to other types of radiation.”

它只是和其他类型的射线比了，但是并没有说明ultraviolet radiation和之前比是不是less了，人家题目只是说以前的紫外线比现在的少啊云云之类的，所以假设中要有时间上的纵向对比。


所以你看ABC选项都有时间上纵向的对比，DE选项都是同类间的横向对比（D是不同的animals，E是不同的radiation）,所以最先排除的就应该是DE了。

恰巧新三十六套增添了这一道逻辑题，没有答案，看了你的解释豁然开朗，谢谢！

第四题少了一层逻辑：
1.没有不参加course的人能拿到执照
2.所有的CT学生在毕业前都要参加这个course
3.因此，所有CT的毕业生都有执照
缺乏一层逻辑：参加了这个course的人就能拿到执照？
即course是执照必要条件而不是充分条件
