Archaeological Artifacts in Harappan Towns

Inferences 1 and 2 can be correctly drawn from the statements. Inference 1 is correct because the presence of handheld terra-cotta or terracotta spindle-whorls without mechanized wheels shows that yarn production was a manual, household activity. Inference 2 is correct because discovering standardized chert weights and ivory linear scales with systematic graduated markings confirms that the Harappans possessed advanced, uniform scientific and mathematical knowledge. Inference 3 is incorrect because spacious multi-room brick houses with personal wells and private bathing platforms indicate the growth of deep social stratification and private wealth, rather than an egalitarian 'common property system'.
