Day 80
1. 抓鱼的渔网
有个鸟port地方捕鱼,用一种grill(?貌似,反正是g看头的单词),然后这种东西会在捕鱼的时候干掉很多珍稀鱼类,于是当地渔业委员会强制推广一种渔网,这种网捕鱼之后抓得珍稀鱼类会放掉,在鸟地方的很多渔船已经开始用了,因此结论是这个新渔网措施的implement会保护珍稀鱼类的时候不伤害当地渔业经济.
削弱题
选项有 A,这个措施实行之后渔船少了好多;
B,那个g啥啥的即使小心使用也比新发明的渔网容易坏.
C,这个珍稀鱼被recreational神马抓走的比被渔船抓走的多,
D,这个鱼变这么in danger不是因为原来那个捕鱼的鸟东西
E,不记得了
P:换渔网
C:这个新渔网措施的implement会保护珍稀鱼类的时候不伤害当地渔业经济
Weaken:
原理:解释为啥新的欲望会伤害经济:渔网不太能正常使用;具体解释这个新渔网如何导致收成下降。
2. P的检测
In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results.
Which of the following, if true, gives the most support to the recommendation above?
A.The accepted treatment for pironoma does not have damaging side effects.
B.The laboratory test that has the lowest proportion of false positive results causes the same minor side effects as do the other laboratory tests used to detect pironoma.
C.In treating pironoma patients, it is essential to begin treatment as early as possible, since even a week of delay can result in loss of life.
D.The proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma.
E.All laboratory tests to detect pironoma have the same proportion of false negative results.
C:physicians should use the laboratory test that has the lowest proportion of false positive result
Support:
- 原理:所有的lab的false negative都一样,因此选择false positive低就好
3. 家庭影院新策略
一厂家生产家庭影院的,发现销量没以前好了,决定做点新的改变,要整个什么没有smoke 款的?计划如果这种新款推出,将吸引更多的消费者。具体什么意思没太整明白,问削弱。
P:整个什么没有smoke 款
C:将吸引更多的消费者
Weaken:
- 原理:否定性副作用(没有smoke款如何损坏现有的客户等);可行性(没有smoke如何无法吸引更多消费者);可操作性(不能造出无smoke款)
