I want to know the answer to the following question:
Who was in charge of counties that had fewer than 10,000 people in them?
All the background I'm provided with is that "He was the top civil and military leader of the commandery and handled defense, lawsuits, seasonal instructions to farmers and recommendations of nominees for office sent annually to the capital in a quota system first established by Emperor Wu.". Is that enough to answer the question?
Answer: no
