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) Minimising soil erosion in nearby agricultural lands		b) Reducing methane emissions from landfills
	c) Curbing air pollution caused by burning waste		d) Mitigating water contamination from landfill leachate

Q.3	You are an environmental scientist analysing water quality parameters from two different sources, Source A and Source B. These sources provide water to nearby ecosystems. Consider the following data table showing water quality parameters from two different sources. Based on this data, which of the statements is most likely true? 1. Higher nutrient levels in Source A suggest an increased likelihood of eutrophication. 2. Source B has higher Dissolved Oxygen and Total Dissolved Solids (TDS) than Source A, implying better water quality for the nearby ecosystems. 3. Lower Dissolve Oxygen levels in Source A indicate the potential for oxygen depletion due to increased organic matter decomposition. D. Hypoxic and alkaline conditions in Source B can lead to the formation of algal blooms. Parameter Source A Source B pH 6.8 8.2 Dissolved Oxygen 2.5 mg/L 5.0 mg/L Nitrate Levels 2.0 mg/L 0.5 mg/L Total Dissolved Solids (TDS) 300 ppm 500 ppm
