坑，mark，是让选择能否判断确定， 那么（1）24 ≤ n ≤ 28，n可以取24、25、26、27、28，这五个数均不是质数，可以确定不是prime numbe，，，，只想着怎么确定是prime了
问是不是的问题。。。一定要想着有是，和不是两个判断方向，而不是只想是的方向去判断

2-> {11,12,13,14,15} 不可能是{12， 13， 14， 15， 16} ，只能有两个偶数

mark，只让比大小（1）就可以，没让算具体值，说了positive，所以1就充分 了

mark， the range of the amounts of money 重点词是range，其他几个project有多重可能，造成range无法确定

with/without the restrictions of A and/or B

take hold 抓住，固定下来，生根，确立

done 结构通常就近修饰

习惯用语-介词 under，表示“协议、法律或制度”的名词常与介词 under 连用，under 在这种情况下的意思是 according to“根据，按照”。

2^96*(2^4-1)

分不清主结论和中间结论时，用therefore把两个结论连接一下，看谁能推导谁就ok了

其他样本问题，枚举推理

shifting boundries。。be charted，边界被绘制。。
问village村庄村民属于哪里
d无法确定这一点

注意认真对照原文重点词汇

a不对是因为： 重点是This policy reduces wastage of police time but results in a loss of protection for some residents.
而不是will not cover the expenses police typically incur when they respond to a false alarm.

D：时间状语从句不对，另外， for example不能把从句隔开； E同理时间状语从句不对，同时When they have a prescription也不对，应该是他们拿到了剂量太少的处方

People will repeat a tale if it fits their purpose. They may not deliberately spread untruths, but neither are they particularly motivated to investigate deeply to determine if the tale they are telling is true.

----investigate deeply to determine if...is ture--->people will not verify the truth of a story that fits their purpose

a不对是因为问题问的是基于什么假设。。。看清题目。。。assumptions： If an animal does not have the capacity for MSR, it does not have the capacity for self-awareness.

B& E 错在also - 无意义，重复，没有C好

if true, ------the most serious weakness in the marketing executive's advice? if true--- most-------
Spending on charitable ventures would require Magu to decrease direct advertisements, which are the most effective means of reaching its target customer。。。。。。most effective means

E项除了固定搭配be known to do错了以外，还有问题是把species做了主语，但已知的应该是人是species 灭绝
