推荐答案

这听起来像某些学习材料的学校作业或案例研究。尝试谷歌或阅读与课程相关的书。没有帮助做一个研究，也没有做它附带的材料和作业。



祝你好运！

It sounds like some school assignment or case study from some learning material. Try google it or read the book associated with the course. No help to do a study and not do the material and assignments that come with it.

Good luck!
