Answer:
His observations about who each pilgrim is, what his/her position in society is, and what he/she looks like.
Step-by-step explanation:
Geoffrey Chaucer's "The Canterbury Tales" is a collection of stories/ tales told by the thirty pilgrims on their way to Canterbury. These tales are told by people from different backgrounds, and from differing professions.
The given excerpt given in the question is from the initial part of "The General Prologue" where the narrator is giving the readers an introduction about the pilgrims before the start of their tales. He states that before he goes on to begin his story, he will first introduce the twenty nine pilgrims in the group. This introduction will give the picture of who they are, what they do and how they are dressed at that moment of the story.
Thus, through the excerpt, Chaucer is going to reveal his observations about the pilgrims, what their positions are in the society and what they look like.
