summarize the rules the host proposes for the storytelling competition. what's the prize? who will be the judge?

What the Host describes is a tale-telling game, in which each pilgrim shall tell two tales on the way to Canterbury, and two more on the way home; whoever tells the tale 'of best sentence and moost solas' shall have supper at the cost of all of the other pilgrims, back at the Inn, once the pilgrimage returns from Canterbury. The pilgrims agree to the Host's suggestion, and agree to accord to the Host's judgment as master of the tale-telling game. Everyone then goes to bed.
