弱弱的问下，那个他们所说的狗狗使用是什么？

camelo777

对你的理解是正确的，E就是说就算有tax code也提高不了saving，因为这个年纪的saving 历来是很低的

狗狗就是一些考完试的同学把考试中能回忆起来的内容分享给大家，因为在一段时期内的题库是一样的，狗狗就是JJ，你可以去搜索一下就知道了

B是一个必须的假设，如果取非的话，变成换新车的cost会超过你的收益，那不就是亏了吗？所以这个取非会削弱，所以是必须的假设。

D不是一个必须的假设，好不好开无所谓，能赚钱就可以，题目要讨论的是换新车是不是能继续盈利，D无关

The cities with the densest population have the highest ratio of police officers to citizens. Such cities also have the lowest rates of property crime without contact between perpetrator and victim. Thus maintaining a high ratio of police officers to citizens can serve as an effective deterrent to at least certain kinds of property crime.
Which of the following, if true, most seriously weakens the argument above?
(A) The quality of training that police receive varies from city to city.
(B) High population density itself makes it difficult to commit a property crime that involves no contact between perpetrator and victim.
(C) Many nonviolent crimes in large cities are drug-related.
(D) A majority of the perpetrators of property crimes in densely populated cities are not apprehended by the police.
(E) Property crimes without contact between perpetrator and victim represent only a small proportion of overall crime.

答案是B，但是我觉得d；好像也可以，因为那些crime不归警察管的话，不就可以说那些police officer没有用吗？还有b是什么意思？

我不知道..我没有做过那个...你去论坛里搜一下吧，或者google以下有没有

B是给出了一个他因，B说因为人口太密集了，property crime 本身就变的困难了，所以这个犯罪率才这么低，不是因为警察多了的缘故。
D不对是因为它没有给出解释，就算这些crime不归警察管，但是有可能因为这些警察的存在而启到了震慑的作用也说不定，所以D没有削弱题目的结论。

People living in the undeveloped wilderness area want jobs, and commercial development of the area will create jobs. But if the new commercial development plan is carried out, the wilderness will suffer. Thus the board considering the area’s future must choose between the preservation of the wilderness and the wishes of the local people.
The answer to which of the following questions would be LEAST relevant to evaluating whether the board indeed faces the choice the author says it faces?
(A) Could commercial development be carried out under an alternative plan without damaging the wilderness?
(B) Would commercial development of the wilderness area significantly benefit people living elsewhere?
(C) Would the jobs created by the new development plan be filled by the local people?
(D) Do local people support or oppose commercial development of the wilderness area?
(E) Can job be provided without commercial development of the wilderness area

答案是B，可是我觉得那个工作不是用来提供给当地的居民的吗？为什么要问有利于外面的居民？
还有，想一般的评价题要怎么做。我做评价的时候老是没方向感。

camelo777

因为问的是least啊，是选最不相关的，所以外面的居民就是无关了，你要读清楚题。简单的来说评价题答案取正支持，取非削弱
