Q.1	You're at the supermarket deciding between locally-grown organic vegetables and conventionally-grown vegetables shipped from a distant country. Both cost the same. Considering climate change:
	a) The local organic option is always better due to reduced transportation emissions.		b) Choose conventionally grown vegetables, as organic farming uses more water.
	c) Consider additional factors like packaging and water usage alongside transportation emissions.		d) Both options have similar climate impacts, so focus on personal preference.

Q.2	A city council plans to implement a policy mandating the separation of organic waste (such as food scraps and yard waste) from other household garbage. Which environmental impact is most directly addressed by this policy?
	a) Reducing methane emissions from landfills		b) Minimising soil erosion in nearby agricultural lands
	c) Curbing air pollution caused by burning waste		d) Mitigating water contamination from landfill leachate

Q.3	Consider the following statements and choose the correct option: 1. Debris accumulation in oceans primarily consists of organic waste, which enhances marine biodiversity by providing habitats for various species. 2. Sustainable aquaculture involves utilising antibiotics to control diseases and enhance fish growth in farms. 3. Coastal development and shoreline alterations significantly impact marine habitats or disrupt the natural flow of sediments in coastal areas. 4. Overfishing contributes to the creation of dead zones due to the imbalance in marine ecosystems caused by the removal of certain fish species.
	a) Statements 1 and 2 are correct but statements 3 and 4 are incorrect.		b) Statements 1 and 2 are incorrect but statements 3 and 4 are correct.
	c) Statements 2 and 4 are incorrect but statements 1 and 3 are correct.		d) Statements 1 and 3 are incorrect but statements 2 and 4 are correct.

Q.4	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.
