Day 45
1. 飞机航空业
还有一题说航空业 internet发达了 很多人网上交流了 business出差也减少了 所以对航空业必定是个很大的冲击 问assumption
我的答案: 网上交流会取代面对面的交流
Language 答案: 网上交流多了,航空业利润受损
假设-取非削弱,网上交流多了,出差少了, 买票的人也少了,所以利润下降了。答案-机票销量的减少所带来的损失没法从别的方面弥补
2. 抢地盘
说一个地方有本土的 fox,他们本身数量正常,但是某年某日,带来一 种新的 red fox,他们来了以后导致本土 fox 的数量锐减,但是发现 red fox 并没有影响本土 fox 的捕猎,也木有侵占本土 fox 的领地,问到底 是肿么回事。
Red fox comes, it follows that local fox number declines sharply; however red fox did not affect the preys and habitat of the local fox. Explain
My answer: They fight with each other and red fox killed local fox, or drove local fox away
3. 经济现象
Rate of return on stocks is higher than that of bonds because stocks are more risky. However, research has found that the potential returns of stocks/bond do not balance with their respective risks. This is because financial planners tend to prefer lower risks, leading to a higher demand for bonds. Therefore we see the impact on the returns. Assumption?
Language answer: there are no other parties of financial players who prefer high risks that has a higher return
