Answer

Chaucer draws on the  ESTATES satire prevalent in his time to bring out the traits of the different classes of society. He uses the technique of  FRAME story to hold the narrative together.

Explanation:

Geoffrey Chaucer's "The Canterbury Tales" is a frame narrative story told by numerous pilgrims on their way to Canterbury. The tales told by the different characters all reflect their true selves, according to their professions and backgrounds.

In this tale, Chaucer draws on the estates satire which is a writing genre that focuses on the societal classes of the time. Most writings of this genre occurs during the Medieval times where class/ status plays a huge role in the identification and understanding of a person.

Chaucer also uses the technique of a frame narrative to make the stories stick together. This type of frame narrative is when a story is included in the main story, like different sub-branches from the main part. In simple words, we can say a frame narration is "a story within a story". This happens when a narrator tells a story about a person who then narrates a story too.
