Which of the following was the unique feature of the Mohenjo-Daro, not found in any other ancient civilization? A) Double storeyed houses B) Wide roads C) Underground drainage systems D) Citadels
Hint: The word Mohenjo Daro is used to mean "dead mound," and the site's archaeological significance was first recognised in 1922. Following excavations, it was discovered that the mounds hold the ruins of the Indus civilization's largest settlement.
Complete answer: Double storeyed houses: The architecture of Mohenjo Daro is planned, with multi-story buildings organised in a grid pattern. The majority is made of fired and mortared stone, with some sun-dried mud-brick and wooden superstructures mixed. Double storeyed houses were not a unique feature of Mohenjo-Daro. Hence this is not the correct answer.
Wide roads: The major roads had a width of 9.75 metres. A wide road was not a unique feature of Mohenjo-Daro. Hence this is not the correct answer.
Underground drainage systems: Mohenjo-Daro had quite an impressive drainage system. The house's water drained through the streets, which had drained. Manholes were installed in the street drains. No other bronze-age civilization placed such an importance on health and cleanliness as the inhabitants of the Indus Valley. Hence this is the correct answer.
Citadels: The citadel, or 'acropolis,' is the part that was constructed on a higher level. The citadel included public buildings such as Mohenjo Daro’s Great Bath and Granary, as well as religious structures. Citadel was not a unique feature of Mohenjo-Daro. Hence this is not the correct answer.
Therefore, the correct option is C) Underground drainage systems.
Note: R. D. Banerji was an officer of the Archaeological Survey of India. He discovered Mohenjo Daro in 1922, two years after major excavations at Harappa, 590 kilometres to the north.
