On my FAR exam, I used the research page to try to help find the answers to the communication portion. For example, if they ask what the difference between Cash Basis and Accrual Basis accounting is, you can look up the definition of revenue and/or expense. Or if they ask you what kind of internal controls you would recommend to a small business, look up the purpose of internal controls and reference them and then try to think of specific controls that will fulfill those purposes. If they ask you about substantive analytics in an Audit exam, and how you would use them to mitigate risks, you can even look that up in the accounting literature.
If you are able to find information in your research tab that directly speaks to the question you are being asked, then you are golden. Not only do you get to sound really smart by referencing the authoritative reference number (although they will make sure that you are keeping your audience in mind so if you are writing to a client, you don't want to just throw APB and FAS #'s at them) but you can also be 100% certain that what you are saying is factual. Plus authoritative reference automatically includes those keywords that I know the examiners are looking for.
