Day 40
1. 修桥
一个地方要修桥。修桥的钱要从民众募集。但是这个桥只有一部分居民经常使用，另一部分住在偏远地方的人用不上。所以向所有人募集钱是不公平的。Assumption
答：
假设题
假设：偏远地方的人不会间接受益于修桥

2. 珍稀白鲸
有一种珍稀白鲸 死亡率很高 而且原因是因为colison（忘了怎么拼了就是撞击那个单词）with ships 所以就调低了在某些白鲸密集区域船只航行速度的limit 果然白鲸数量上升了 说明政策有效 问还需要知道什么条件 我选的是在没限速的区域白鲸的数量
答：
假设题
政策没有改变该区域船只的数量

3. 三文鱼和小虾米
The economy around Lake Paqua depends on fishing of the lake's landlocked salmon population. In recent years, scarcity of food for salmon there has caused a decline in both the number and the size of the adult salmon in the lake. As a result, the region's revenues from salmon fishing have declined significantly. To remedy this situation, officials plan to introduce shrimp, which can serve as a food source for adult salmon, into Lake Paqua.
Which of the following, if true, most seriously calls into question the plan's chances for success?
(A) Salmon is not a popular food among residents of the Lake Paqua region.
(B) Tourists coming to fish for sport generate more income for residents of the Lake Paqua region than does commercial fishing.
(C) The shrimp to be introduced into Lake Paqua are of a variety that is too small to be harvested for human consumption.
(D) The primary food for both shrimp and juvenile salmon is plankton, which is not abundant in Lake Paqua.
(E) Fishing regulations prohibit people from keeping any salmon they have caught in Lake Paqua that are smaller than a certain minimum size.
答：
D

其他人不是必须通过这座桥跟偏远地区的人联系？

船只数量没变

光考虑adult不合适吧，是不是得考虑young salmon，D

1.修桥：
假设住在偏远山区的人绝对不会用桥，不考虑其间接用桥的情况（eg:如偏远地区的粮食的供应的车辆需要通过这座桥）

2.珍惜白鲸：
即控制变量。如果限制前区域的白鲸数量比限制后同一个区域的白鲸数量多，则该政策的信度缺乏说服力，所有还需要知道限制区限制前后白鲸的数量。

3.D。虾的引入是为了增多三文鱼的食物来源，如果虾和三文鱼的食物来源有重叠，则虾的引入可能会减少三文鱼的食物来源，从而使得三文鱼数量进一步减少。

按照使用频率收费是公平的

没限速的区域白鲸的数量就很少

1. 修桥
一个地方要修桥。修桥的钱要从民众募集。但是这个桥只有一部分居民经常使用，另一部分住在偏远地方的人用不上。所以向所有人募集钱是不公平的。Assumption

P：一部分偏远的人用不上桥却要给钱修桥
C：向所有人募集钱不公平

逻辑：太远了用不上桥却要给钱-不公平
gap：1.修桥对偏远的人是否有用桥以外的好处
2.虽然偏远不容易用桥，但必要时是否很有用
3.公平的定义？
assumption：
1.修桥不是偏远的人去某地的必经之路
2.公共事务都是一起给钱的，其他好处那些不偏远的人捞不到也同样要给钱

2. 珍稀白鲸
有一种珍稀白鲸 死亡率很高 而且原因是因为colison（忘了怎么拼了就是撞击那个单词）with ships 所以就调低了在某些白鲸密集区域船只航行速度的limit 果然白鲸数量上升了 说明政策有效 问还需要知道什么条件 我选的是在没限速的区域白鲸的数量

背景：和船撞击导致白鲸死亡率高
事实现象：白鲸数量上升
相关现象：此处限制了船速
C：限制船速可以导致白鲸数量上升
gap：是否有其他原因导致白鲸数量上升
同意狗主答案，有可能那段时间白鲸数量就是上升了

目的：增加成年三文鱼数量
方案：增加shrimp
有效性：shrimp并不足以挽救食物少的状况/shrimp会被其他鱼吃掉
副作用：shrimp导致三文鱼的predators更多

Which of the following, if true, most seriously calls into question the plan's chances for success?
(A) Salmon is not a popular food among residents of the Lake Paqua region.
(B) Tourists coming to fish for sport generate more income for residents of the Lake Paqua region than does commercial fishing.

D ABE都没提到方案
C无关
