97. What is the environmental effect of urbanization on rural wildlife populations?
(A) Increased habitat availability
(B) Habitat fragmentation and population decline
(C) Enhanced species migration
(D) Increased food availability
(B) Habitat fragmentation and population decline
Explanation: Urbanization often leads to habitat fragmentation, making it difficult for wildlife to migrate and survive, which contributes to population decline.
98. What is a solution to mitigate the impacts of water pollution in both rural and urban areas?
(A) Use of more chemicals in agriculture
(B) Treatment of industrial effluents and sewage
(C) Encouraging deforestation
(D) Increased consumption of water
(B) Treatment of industrial effluents and sewage
Explanation: Treating industrial effluents and sewage before they are released into water bodies can significantly reduce water pollution, improving water quality in both rural and urban areas.
99. Which of the following urban practices helps reduce the urban heat island effect?
(A) Increasing the use of concrete and asphalt
(B) Expanding green spaces and urban forests
(C) Constructing more industrial buildings
(D) Reducing the amount of green roofs
(B) Expanding green spaces and urban forests
Explanation: Expanding green spaces and urban forests helps cool the urban environment by providing shade, increasing evapotranspiration, and reducing the absorption of heat by impervious surfaces.
100. What is one of the major consequences of the over-extraction of groundwater in rural areas?
(A) Improved water availability
(B) Reduced water table levels and water scarcity
(C) Increased soil fertility
(D) Increased water quality
(B) Reduced water table levels and water scarcity
Explanation: Over-extraction of groundwater depletes aquifers and lowers the water table, leading to water scarcity in rural areas, which can impact agriculture and local communities.
