The document is a history assignment asking students to answer questions based on three sources about the Qin dynasty in China. Source A describes how weapons found with terracotta warriors were well-preserved and had chrome plating, showing advanced metalworking techniques. Source B states that Emperor Qin Shi Huang adopted legalism to strengthen rule and unified the empire through harsh punishments, though later dynasties were less severe. Source C notes Emperor Qin Shi Huang only allowed legalism and banned other philosophies, burning books. He built the Great Wall using forced labor, causing resentment, and made people work without pay on other projects like roads and his tomb.
