1
小孩

有个说玩block的小孩对文字理解更好 做个试验小孩分成玩block和不玩的考察他们的communication能力 结果玩block的好 so家长要多让小孩玩block

type：evaluation
reference answer:

E 玩block的小孩家人有没有对小孩有verb训练 （大概意思）

讨论

结论：家长让小孩玩block

原因：试验显示玩block的小孩比不玩block的小孩的communication能力高

分析：看试验对象的差异， 如果玩或不玩block是两组试验对象的唯一差异， 则能说明结论成立， 如果还有其它差异， 如 玩block的有verb训练， 则结论不成立

2  捕鱼
有一道很简单的逻辑，GWD有的，说要保护一种鱼，然后引入旅游业，让捕鱼的去搞旅游，问你要考虑神马问题，
type:
RA:
应该就是旅游带来的危害和捕杀相比会不会更严重。

考古（来自brendaqian）：
In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat.  Having noted the manatee hunters’ expert knowledge of manatees’ habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.  Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees’ survival.

Which of the following, if true, raises the most serious doubt about the plan’s chance of success?
1.Many tourists who visit these parts of the Caribbean are uninterested in manatees and would not be willing to pay what the former manatee hunters would have to charge for boat rides to see manatees.
2.Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again.
3.In areas where manatees have traditionally been hunted for food, local people could easily replace the manatee meat in their diets with other foods obtained from the sea.
4.There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees.
5.To maintain their current income, manatee hunters who switched to guiding tourists would have to use far larger boats and make many more trips into the manatees’ fragile habitat than they currently do.

3 用小孩实验
V1：还有个说children 用的药经常用adults做实验，government为了鼓励用children做实验，给那些企业发个patent，这样会有most profits，
问你考考虑神马问题，

5 whale 与海狮
whale吃海狮，由于海狮在80年代之后数量剧减，所以专家认为这是天敌whale增加的结果，问weaken。
我选了有个选项说，正如鱼吃什么一样，反正不是whale的原因。

6  戒烟
这次我碰到的逻辑都很简单。。题目都不太记得了。。只记得一个smoke的抽烟造成的health cost 让政府决定宣传戒烟。但是戒烟后的人都会发胖(导致胖病 = =），也会increase health cost，所以宣传戒烟也不会降低health cost.

问哪个论据可以支持政府倡导戒烟降低cost.
我选的是很大一部分health cost是人们吸二手烟导致的

7： baby  food
一个研究机构调查市场上baby food preservative，说都低于政府公布的data，所以婴儿吃这些food不会有坏处，
问削弱，
我选了因为成人和婴儿的能接受的preservative不同。

8： corn and profit
corn的price受数量影响，数量多价格就低，数量少价格就高，农民有储存corn的习惯，为的是得到高的profit。  this year corn数量很少，但是价格并没有升高，
问为什么？

10.  旅游  环保（不全，待考古）
