The verified response to “Ancient History question: Which river or river-region is associated with Dholavira?” is Mansar-Manhar system, option B. The original question-specific evidence states: Dholavira is associated with the Mansar-Manhar system region. Mansar-Manhar system is the correct answer to “Which river or river-region is associated with Dholavira”. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. The choices Pravara, Indus and Saurashtra coastal region do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Mansar-Manhar system as the keyed response for this Ancient History question.
