Question

what was a major reason the qin dynasty collapsed shortly after unifying china? natural disasters immediately ruined crop production; succession disputes peacefully transferred authority; harsh rule and peasant revolts weakened its control; frequent foreign invasions destroyed its armies

Explanation:

The Qin Dynasty had harsh legalist rule with heavy taxes, forced labor (like the Great Wall), and strict punishments. This led to peasant revolts (e.g., Dazexiang Uprising) that weakened its control. Natural disasters weren't the main collapse cause, succession disputes weren't peaceful (e.g., Huhai's usurpation), and foreign invasions weren't frequent then. So the correct option relates to harsh rule and revolts.

Answer:

C. Harsh rule and peasant revolts weakened its control
