作文
a real estate agent mentioned the below:
"Over the last five years, the housing prices in our city have doubled. During the same time, the stock market has fallen. So now it is a good time for the city residents to buy houses as an investment. In additional, home owners can also live in the houses they bought and that can improve one's quality of life, whereas there is no such similar benefit if one buys stocks."

1. car dealer
-because cars nowadays are not distinguishable in terms of quality and functions, car dealers need to distinguish themselves via sales and services.
-sales and services are defined whether they are "best in kind." Customers define "best in kind" services as being able to have their cars fixed in one-go. 35% of the time car dealers cannot fix customers' cars in one go
-traditional mindset to solve this problem is to improve training for technicians at car delears.
-but there are three reason why such training approach actually cannot improve services for clients.
2. medevial women
这篇挺长的，有1.5屏，很多细节题，估计是难题库。
p1
-medevial time was considered a "golden time" for women in a lot of historians' minds. These historians believe that women's economic rights did not deteriate until 16th and 17th century when industrial revolution happened.
-mentiond two historians' studies to support the above conclusion. The studies were all about women in the 16th and 17th century.
p2
- but we cannot use evidence about women in the 16th and 17th century to argue points about women in the 15th century
-such economic deteriation for women in fact happened before 16th century. Quote some evidence to support this conclusion
P3
-There are some historians who are still very adament about believing women during Medeival time was doing fine.
-for example, quote two historians' studies and argue how they were flawed and over-simplified.
3. innovation in big vs. small companies
p1
-common belief is that big companies are more effective in their research and development (R&D) work and can get more out of R&D investment.
-but that is actually not the case. Small companies can actually get more out of their R&D investment than big companies can.
p2
-why can small companies get more out of their R&D investment than big companies can?
-once a new technology/ knoweldge is developed, it is very different to ring-fence. So over time other people will know this knowledge.
-small companies get as much knowledge from this "R&D" spillover as big companies do. Yet small companies pay less for R&D than big companies.
-so small companies get more bang for their buck
逻辑
1. somebody did a research on the relationship between people being kind to their spouses and their happiniess level. the researcher concluded that people being kind to their spouses will lead to higher happiness level. How to strengthen the argument?
答案是researcher found out that just because people are happier, it doesn't mean they will be nicer their spouses.
