Q.1	In a nature reserve, a team of ecologists is assessing the impact of biodiversity on ecosystem resilience following a natural disaster. Which statement best describes the relationship between biodiversity and ecosystem resilience?
	a) Increased biodiversity directly weakens an ecosystem's ability to withstand disturbances.		b) Diverse ecosystems are more prone to invasive species due to the abundance of niches.
	c) Higher species richness leads to greater stability and ability to recover from environmental changes.		d) The number of unique species has no significant impact on an ecosystem's overall health.

Q.2	Blair, an environmentally conscious consumer, is shopping for groceries at a local store. She notices a food product with an eco-label that states "Organic" on the packaging. Curious about its meaning, she checks the information available to understand the significance of the label. In the context of eco-labelling, what does the presence of an "Organic" label on a food product signify based on Emily's observation?
	a) The product is made using recycled materials.		b) It is manufactured using renewable energy sources.
	c) It's produced using sustainable farming methods without synthetic pesticides or fertilisers.		d) It contains natural ingredients.

Q.3	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.4	A power plant generates electricity using coal as its primary fuel source. The burning of coal releases various pollutants into the atmosphere, including carbon dioxide, sulphur dioxide, and nitrogen oxides. These pollutants can have significant environmental and health impacts. Which of the following statements accurately describes the relationship between coal combustion and air pollution?
	a) Coal combustion directly leads to air pollution, and the severity of pollution is proportional to the amount of coal burned.		b) Coal combustion is an indirect cause of air pollution, as the pollutants released during combustion interact with other atmospheric components to form harmful compounds.
	c) Coal combustion is the sole source of air pollution, and other factors, such as vehicular emissions and industrial activities, have negligible effects on air quality.		d) Coal combustion is a necessary evil for electricity generation, and the environmental consequences are outweighed by the economic benefits of reliable energy.
