For problem types, maybe give an example problem from a past CMO. I need to create a hypothetical example if I don't have a real one. Wait, but if the report is about the CMO in general, maybe not providing a specific problem is better unless I can ensure accuracy. Alternatively, refer to types of problems without giving exact solutions. Or perhaps mention that the problems are similar to international olympiads in style.
