坐稳：
From a memo of a manager in a Fitness company:
A recent survey of our customers indicates that most people are interested in eating healthier. Organic food is food without chemical... bulabulabula. Based on the survey, our city is ready to support organic grocery stores. I recommended that our company expands a section of an organic store in each fitness center every location, before national chains come into the city. So our company can increase benefits which have remained stable in the past few years.

IR:

应该小于60吧……也没思路，求高人解答

最后一题不对啊，怎么算都是30度？180-90-60然后除以2=15，90+15=105，60-15=45，180-105-45=30？

方脸团子

嗯，算错了，是60度……60看成90，脑子秀逗

Checked, but I don't think there is much similarity between the two tests. Sorry for the late reply.
