@anjanja,
Everyone has minutes. Auditors have to read the minutes each quarter, year end and subsequently, make summary notes and keep in the audit file.
Your RMM question: The purpose of equation is to keep 1 item ‘fixed' at all times. Your question says ‘to keep the audit risk at same level', right? So the options are moving the equation elements up and down and asking you what to do to keep audit risk at the same point.
If RMM goes up, wonderful. You can't change that, something made it go up => Either the entity is in a risky environment or the Controller is a moron (inherent risk) or your control environment was designed by a toddler (control risk).
The question doesn't tell you which one kicked the RMM up, correct? If you increase your inherent risk, or assume inherent risk should go up as well as RMM, then your AR will go up as well. You don't want that.
Unless the question asks you to fix the problematic risk, you always attack the other item in the equation. RMM went up? Let's work on more effective substantive testing techniques so DR will go down. DR went up? We need to test OE of controls, and do it well to decrease CR.
Evidence question:
Persuasive evidence = Evidence that satisfies the explanation you received from a client.
Conclusive evidence = Evidence that satisfies auditor's conclusion at the assertion level.
Edit based on your DR vs. RMM note;
DR is independent from RMM. RMM is based upon IR and CR, both of which exist independent of your audit/auditor. DR is based on the audit, hence has an inverse relationship with RMM.
