The verified response to “Ancient History question: The Harappan social order is often described as:” is Relatively egalitarian, option D. The original question-specific evidence states: Archaeological evidence suggests a relatively balanced social structure rather than a rigid caste order. Relatively egalitarian is the correct answer to “The Harappan social order is often described as:”. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. Harappan evidence must be interpreted from excavated settlements, artefacts, environmental data and comparisons among sites; a single object should not automatically support a wider claim than the evidence permits. The choices Caste-based, Slave-based only and Feudal do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Relatively egalitarian as the keyed response for this Ancient History question.
