fred is writing a literature review for his research proposal. he selects several books and peer-reviewed papers related to his subject. fred has pared down his list of reading materials so that they will not include redundant or unnecessary information. there is one new area of discussion directly related to his problem area which fred has selected a reading on but he doesn't really understand the findings of this research and he is running short on time so he chooses to leave it out. has fred made a good decision?
