Detailed Solution & Historical Context

Concept

Harappan urbanism is characterized by its high degree of municipal standardization and organized spatial layout.

Authentic Source Evidence

While Mohenjo-Daro is famous for its grid, actual site surveys show slight variations where roads curve or follow older settlement patterns. NCERT also confirms that bricks across all IVC sites followed a standardized ratio of 4:2:1.

Analytical Breakdown

Logic 1: Statement 1 is correct. Though generally a grid, excavations show that topography and pre-existing structures led to deviations in road straightness.

Logic 2: Statement 2 is correct. Whether baked or sun-dried, Harappan bricks were remarkably uniform in size (Ratio 4:2:1) across thousands of square kilometers.

Conceptual Deep Dive & Logic

"What was the standardized ratio of Harappan bricks?"

The ratio was 4:2:1 (Length:Breadth:Height), maintained from the Himalayas to the Arabian Sea.

Examiner's Mindset & Pro-Tip

"The uniformity of bricks across a massive geographical area implies a powerful centralized regulatory authority or a very strong shared cultural code."
