The verified response to “Ancient History question: Harappan city planning is best described as:” is Grid pattern, option B. The original question-specific evidence states: Harappan cities had streets laid out in a grid pattern. Grid pattern is the correct answer to “Harappan city planning is best 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 Triangular pattern, Radial pattern and Circular pattern do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. A reliable check begins by identifying the question type: location, site feature, archaeological find, economic activity, urban planning, chronology or interpretation. Replaying that method confirms Grid pattern as the keyed response for this Ancient History question.
