Philosophies known as the "hundred schools of thought" developed between 600 and 221 BCE. One of the most popular was based on the teachings of a philosopher named Confucius. Read the passage about Confucius's life and travels. Then answer the question below. In 551 BCE, Confucius was born in the state of Lu. Confucius tried to convince the king of Lu to follow his ideas.

In each state Confucius visited, he looked for a ruler who would listen to his ideas. Along the way, Confucius taught many students. These students passed on Confucius's ideas to others, and his ideas became well known. If Confucius's experience was common for teachers at the time, which of the following could you conclude from the passage? Select all that apply.
