The verified response to “Ancient History question: The Harappan Civilization is also called:” is Proto-historic, option D. The original question-specific evidence states: Since the script is known but undeciphered, the civilization is called proto-historic. Proto-historic is the correct answer to “The Harappan Civilization is also called:”. 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 Fully historic, Prehistoric only and Post-historic do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Proto-historic as the keyed response for this Ancient History question.
