This is my first time to deal with case study in the university so the question may seem silly. The professor of my marketing class sent us some background info about a restaurant and asked us to answer some questions he mentioned at the end of the document. The doc is mainly some history and strategy about the restaurant. Should I search for other data/information about my case, for example visit their website or look for some statistics? Or just write my essay as the answer to some reading comprehension questions?
