Q.1	Your village receives heavy rainfall during the monsoon months of July and August as shown in the graph below. However, the remaining months experience significantly less rainfall, leading to water scarcity during the dry season. What would be the most effective strategy to address this water scarcity issue? 1. Plant more trees throughout the village to increase overall rainfall. 2. Implement rainwater harvesting systems on every household rooftop. 3. Educate villagers about water conservation practices and rainwater harvesting techniques.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.2	In a village, there lived a young girl named Maya. She loved exploring nature and understood the importance of conserving natural resources. Why did Maya think conserving soil was essential?
	a) Because soil erosion doesn't impact farming.		b) Because healthy soil is vital for growing crops and preserving biodiversity.
	c) Because soil degradation doesn't affect water quality.		d) Because adding chemicals to the soil benefits the environment.

Q.3	Sarah watches how camels survive in the hot desert. What adaptations of camels, observed by Sarah, to survive in this harsh desert habitat?
	a) Long eyelashes, ear hairs, fat storage in humps, specialied kidneys		b) Having retractable claws for better grip on sandy surfaces.
	c) Ability to flatten their bodies to absorb heat from the desert sand.		d) Ability to close their nostrils to prevent sand from entering while breathing.

Q.4	In a study comparing the environmental effects of traditional light bulbs to energy-efficient LED bulbs, researchers found that LED bulbs contribute to reducing greenhouse gas emissions. What feature of LED bulbs contributes to this positive outcome?
