Harappa was indeed a well-planned city, and its drainage system was one feature of that planning, but drainage alone doesn't explain the full scope of urban planning. Both statements are correct, but the reason is incomplete.

The Harappan civilization (c. 2600–1900 BCE) represents one of the earliest examples of sophisticated urban planning in human history. When we say a city is "well-planned," we mean it shows evidence of deliberate design, standardization, and forethought in its layout—not haphazard growth.

Harappa and other Indus Valley cities demonstrate this through multiple features: a grid pattern of streets intersecting at right angles, standardized burnt bricks (in a ratio of 4:2:1), a clear division between the citadel (raised platform with public buildings) and the lower town (residential areas), uniform house construction, and yes, an elaborate drainage system. The planning extended to weights and measures, which were standardized across the civilization.

Now let's examine both statements:

  1. Assertion (A): "Harappa was a well-planned city"

    This is unquestionably correct. Archaeological evidence from multiple Harappan sites confirms systematic urban planning. The regularity of street layouts, the standardization of construction materials, and the functional zoning all point to centralized planning authority.

  2. Reason (R): "It had a well-planned drainage system"

    This is also correct. The drainage system was remarkably advanced: covered drains ran along the streets, house drains connected to street drains through ceramic pipes, manholes allowed maintenance access, and soak pits filtered wastewater. This level of sanitation engineering was unmatched in the ancient world.

  3. Does (R) correctly explain (A)? …
