3000 words, 16 primary resources, 2 secondary resources, 2 general resources. please be based on the introduction draft that I have attached below. the literature review must be based on those questions “research questions” in the introduction. each question must be explained and must be a hypothesis (proposed relationships between the variables) that explains each question.- variables are also included in the introduction part. => analyzing and interpreting data, suggest key-dependent and independent variables.
at the end of the literature review, please also present a model (a graph) to make a better understanding. if you have any better research questions in mind, please feel free to change them and adapt them better to our introduction (that would be really helpful).

Along with the introduction draft attached, please also find some background information about CAT (the company).
please when you are finished with the literature review, attach a word document with all the sources you used for it.
