Read the passage carefully and answer the following questions:

Supply of water to rural settlements in developing countries is not adequate. People in village, particularly in mountainous and arid areas have to walk long distances to fetch drinking water. Water borne diseases such as cholera and jaundice tend to be a common problem. The countries of South Asia face conditions of drought and flood very often. Crop cultivation sequences, in the absence of irrigation, also suffer.

The general absence of toilet and garbage disposal facilities cause health related problems.

The design and uses of building materials of houses vary from one ecological region to another. The houses made up of mud, wood and thatch, remain susceptible to damage during heavy rains and floods, and require proper maintenance every year. Most house designs are typically deficient in proper ventilation. Besides, the design of a house includes the animal shed along with its fodder store within it. This is purposely done to keep the domestic animals and their food properly protected from wild animals.

Unmetalled roads and lack of modern communication network creates a unique problem. During rainy seasons, the settlements remains cut off and pose serious difficulties in providing emergency services. It is also difficult to provide adequate health and educational infrastructure for their large rural population. The problem is particularly serious where proper villagisation has not taken place and houses are scattered over a large area.

Which one of the following is not a rural settlement problem?

Congested housing and streets

The correct answer is Option (4) → Congested housing and streets

Congested housing and streets are typically more characteristic of urban settlement problems rather than rural settlement problems. Rural areas generally have more open space and lower population density compared to urban areas, which may experience issues related to congestion in housing and streets due to higher population concentrations. In rural areas, challenges are often related to infrastructure, basic services, and access to resources rather than issues of congestion.
