Final answer:
Machaut held the positions of Court musician, Secretary, and Farmer, but not Bishop.
Step-by-step explanation:
Machaut held the positions of Court musician, Secretary, and Farmer during his career. The position of Bishop is not one that Machaut held. As a court musician, Machaut composed music for the French royal court, including chansons, motets, and mass settings. As a secretary, he held an administrative role, managing correspondence and paperwork. However, there is no evidence to suggest that Machaut was a bishop. Finally, Machaut was also known to be a farmer, owning and managing agricultural land in his hometown.
