Answer:
Approving tone.
Step-by-step explanation:
In Geoffrey Chaucer's "The Canterbury Tales", the prologue gives a details of the pilgrims travelling to Canterbury Cathedral. The narrator gives a short introduction of all the pilgrims before their actual journey to Canterbury.
The description of the cleric from Oxford shows that not much is given of his appearance except that his clothes were a bit threadbare, suggesting his poor condition. He spent whatever money he gets, even from friends, in buying books about Aristotle. Such was his interest in studies. And whenever he speaks, he just says what's needed and doesn't seem to talk much. The tone used by the narrator in his description of the Oxford cleric is an approving tone, a favorable depiction of his character, not only as a cleric but also as an educated philosopher.
