	a) Land degradation		b) Air pollution
	c) Biodiversity loss		d) Greenhouse gas emissions

Q.2	A city primarily using natural gas for domestic purposes experiences a sudden rise in respiratory ailments among its residents. Which gas, released during incomplete combustion of natural gas, is a major concern for human health?
	a)		b)
	c)		d)

Q.3	A farmer uses a private well to irrigate his crops. He notices that the well water has become increasingly salty over the past few years, affecting the growth and yield of his crops. What could be the most likely reason for this increase in salinity?
	a) Overextraction of groundwater from nearby wells		b) Intrusion of seawater into the freshwater aquifer
	c) Application of fertilisers and pesticides on the farmland		d) Changes in rainfall patterns and natural recharge rates

Q.4	A group of students, with a keen interest in studying a wide array of plant and animal species in their natural habitat, is planning an educational expedition. They aim to explore a biome that offers the highest biodiversity for their research. Which biome among the following options would provide the most diverse range of plant and animal species for the students to observe?
