Read the given passage and answer the four questions that follow: -
Rainwater harvesting is an innovative method to conserve water by collecting and storing rainwater for future use. This practice has been an integral part of Indian culture for centuries, especially in arid and semi-arid regions. It is a simple, eco-friendly technique to address the growing water crisis caused by over extraction of groundwater, climate change, and increasing demand for freshwater resources.
The process involves collecting rainwater from rooftops, roads or open spaces and directing it to storage tanks or underground reservoirs. This water can be used for domestic purposes like drinking, cooking and gardening as well as for recharging groundwater. Several states have made rainwater harvesting mandatory for buildings, significantly improving water availability and management.
One major advantage of rainwater harvesting is that it reduces dependence on municipal water supplies, particularly during droughts. It also helps prevent flooding and soil erosion by capturing rainwater before it runs off into rivers or drains. Moreover, it is cost-effective, environmentally sustainable, and relatively easy to implement even on a small scale.
However, challenges such as lack of awareness, poor maintenance and improper design of harvesting systems hinder its widespread adoption. With proper education, public participation and government support, rainwater harvesting can play a crucial role in water management.
As the world faces increasing scarcity of water resources, rainwater harvesting offers a sustainable solution. By integrating this ancient practice into modern urban planning, we can secure water for future generations while preserving our environment and ecosystems.
A challenge to the widespread adoption of rainwater harvesting is ______.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → lack of awareness and poorly designed systems
The fourth paragraph names the challenges directly: lack of awareness, poor maintenance and improper design of harvesting systems hinder its widespread adoption. "Poorly designed systems" is another way of saying improper design, so Option 1 repeats two of the challenges listed.
Why the Other Options are Incorrect?
Option 2: surplus water availability in cities — Incorrect. Contradicted: surplus means more than is needed, but the passage speaks of a growing water crisis and increasing scarcity, not a surplus.
Option 3: high dependence on advanced technology — Incorrect. Contradicted: the passage calls rainwater harvesting a simple technique that is relatively easy to implement even on a small scale.
Option 4: mandatory government regulations — Incorrect. Contradicted: the passage says several states have made it mandatory for buildings, significantly improving water availability. Government rules and support are shown as a help, not as a challenge.
