Read the following passage and answer the questions:

The regimented cantonment of Harappa may suggest the priest-controlled industries of Sumer. It may even be permissible to propose a priest-king for Mohenjodaro. But all these points, real or imagined, may be ascribed rather to the inherent cousinship of a social phase than to literal, local interchange. They are common generalities, the product of stray seeds readily fertilized in similar historical and geographical settings. The particularities, on the other hand, show abundant and significant local variation. In such sculptural art as the Indus has produced, there is no real affinity with the sculpture of Sumer. No one would mistake a stone carving from Mohenjodaro for one from Tell Asmar or Mari. The Indus terracottas are in a different world from those of Mesopotamia. The art of the Harappan seals has no close parallel in the whole history of glyptic.
