give three details that chaucer uses to characterize the doctor. note if it is direct or indirect

The doctor was a strange man. Chaucer describes him as a man who knows all of the medical authorities by heart, although those medical authorities are based on astronomy and the four humors (sanguine, choleric, phlegmatic, and melancholic), none the less he was also a man who didn't know the Bible. He handed out bogus cures during the plague and made enormous amounts of money; his relationship with local apothecaries enabled him to procure medicines and afforded them all with large profits, and yet he was miserly and didn't spend a penny of it. His favorite thing was gold, the narrator even jokes that the doctor’s favorite medicine is gold.
