Consider the following statements about the archaeological findings in Harappan towns :

I. There is wide occurrence of spindle-whorls in the houses but absence of spinning wheels.
II. Weights and measurement scales, complete with graduations have been discovered.
III. There are houses built in large part with baked bricks, around relatively spacious courtyards, with their own wells, bathing platforms, and large rooms.

Which of the following inferences can be drawn from the above statements ?

1. Statement I suggests that spinning was a laborious activity done at home.
2. Statement II suggests the extent of the scientific knowledge that the Harappans possessed.
3. Statement III suggests the emergence of a common property system.

Select the answer using the code given below :

Inference 1 is correct: The widespread discovery of spindle-whorls in individual houses indicates that spinning was a common domestic activity. The absence of the spinning wheel (which was invented much later) meant that yarn was spun by hand using a drop spindle, making it a slow and laborious process.

Inference 2 is correct: The discovery of standardized weights (typically cubical and made of chert) and graduated measurement scales (such as the ivory scale found at Lothal) demonstrates a high degree of precision, standardization, and advanced scientific and mathematical knowledge among the Harappans.

Inference 3 is incorrect: The presence of houses with their own private wells, bathing platforms, and large rooms points towards individual household autonomy, wealth disparities, and a private property system, rather than a common property system. Common property would be characterized by shared public amenities.

Therefore, only inferences 1 and 2 are correct.
