Here's the final riddle:

Pottermore

The Order of Merlin is awarded by the Wizengamot, an organisation that predates the Ministry of Magic and nowadays functions as a combination of court and parliament.

The Order of Merlin, commemorating the most famous wizard of his time, has been given since the fifteenth century. Legend says that the green ribbon, on which the First Class Order hangs, is to reflect Merlin's Hogwarts house.

The First Class Order is awarded 'for acts of outstanding bravery or distinction' in magic, the Second Class is awarded for 'achievement or endeavour beyond the ordinary' and the Third Class is given to those who 'have made a contribution to our store of knowledge or entertainment.'

While nobody argued when Albus Dumbledore received his O.M. (First Class) for defeating the Dark Wizard Grindlewald, there was a good deal of muttering in the wizarding community when Cornelius Fudge, Minister for Magic, awarded himself an O.M. (First Class) for a career many considered less than distinguished.
