Q.1	Consider the following statements and choose the correct option: Statement 1: Groundwater is primarily recharged through precipitation that infiltrates into the soil. Statement 2: Groundwater, once depleted, can be quickly replenished through human interventions like pumping water from surface reservoirs.
	a) Statement 1 is correct but statement 2 is incorrect.		b) Statement 1 is incorrect but statement 2 is correct.
	c) Both the statements are correct.		d) Both the statements are incorrect.

	a) Choosing locally sourced fruits and vegetables over imported ones.		b) Consuming organic meats instead of conventionally raised meats.
	c) Opting for packaged vegetarian convenience foods.		d) Eating seafood exclusively sourced from sustainable fisheries.

Q.3	During a science fair, a student presented a project on the impact of wildfires on climate change. They highlighted that wildfires release vast amounts of carbon dioxide, methane and nitrous oxide into the atmosphere as shown in the table given below. What inference can be made from this presentation? 1. Wildfires can act as a positive feedback loop, contributing to further warming and potentially more frequent fires. 2. Wildfires are primarily responsible for the rising levels of greenhouse gases in the atmosphere. 3. All wildfires should be suppressed to prevent any carbon dioxide, methane and nitrous oxide emissions. 4. The release of greenhouse gases from wildfires is balanced by the absorption of carbon dioxide by new plant growth.
