Read the passage and answer the questions:
The most ancient system yet discovered

About the drains, Mackay noted: “It is certainly the most complete ancient system as yet discovered.” Every house was connected to the street drains. The main channels were made of bricks set in mortar and were covered with loose bricks that could be removed for cleaning. In some cases, limestone was used for the covers. House drains first emptied into a sump or cesspit into which solid matter settled while wastewater flowed out into the street drain. Very long drainage channels were provided at intervals with sumps for cleaning. It is a wonder of archaeology that “little heaps of materials, mostly sand, have frequently been found lying alongside drainage channels, which shows... that the debris was not always carted way when the drain was cleared”. Drainage systems were not unique to the larger cities but were found in smaller settlements as well, At lothal for example, while houses were built of mud bricks, drains were made of burnt bricks.

2

The correct answer is Option 2 - 2 [(B), (D)only]

Given statements about features of Harappan Civilisation:

(A) It had a planned drainage system. (Correct)
(B) It comprised mostly of rural settlements. (incorrect)
(C) The roads and streets were laid out along the grid pattern. (Correct)
(D) Most settlements have a larger high section and a smaller lower section. (incorrect)
(E) Burials were mostly in the form of pits. (Correct)

Correction:

(B) It comprised mostly of rural settlements.
The Harappan Civilization was predominantly urban, with well-planned cities being a distinctive feature. The civilization had several urban centers with advanced infrastructure, challenging the notion that it comprised mostly of rural settlements.

(D) Most settlements have a larger high section and a smaller lower section.
The settlement is divided into two sections, one smaller but higher and the other much larger but lower. Archaeologists designate these as the Citadel and the Lower Town respectively. The Citadel owes its height to the fact that buildings were constructed on mud brick platforms. It was walled, which meant that it was physically separated from the Lower Town.
