dear candidate great question,

when asked questions thst we are not sure sbout in csse studies we hsve several ways to approsch this. First, we clarify the meanings eg are text… marketing any of the following…? Secondly if still unsure we can answer more broadly. Eg Without further specifying these services, one coukd group them under marketing tools and use the following perspectives to anslyze the situation ( pick your favorite marketing analysis). thirdly we can also ask or make a suggetion what broader question the client msy want to answer with this quetion. eg summarize the results snd potential conclusions of the case so far and propose another data question that you can handle to solve the case eg instead of  marketing could we look at a breakdown of sales with the same customer snd product segments? these are some ways to handle challenging questions in a case .i wish you a lot of success. best wishes.
