Q.1	Dylan is considering buying a new smartphone. He knows that smartphones have a short lifespan and contribute to e-waste. He finds a company that offers a phone made with recycled materials and ethical sourcing practices. Compared to a conventional phone, how would this choice impact Dylan's environmental footprint?
	a) It would only slightly lessen his environmental impact, as smartphone production is inherently resource-intensive.		b) It would significantly reduce his e-waste generation and support ethical labour practices.
	c) It would have a negligible effect, as the majority of the environmental impact comes from smartphone usage.		d) It would increase his footprint due to the higher production cost and potential for shorter lifespan.

Q.2	A community experiences an outbreak of a waterborne disease called Amoebiasis, characterised by severe abdominal cramps, diarrhoea with blood, and high fever. Individuals affected report exposure to contaminated water sources. Identify the causative agent responsible for these symptoms.
	a) Entamoeba histolytica		b) Giardia lamblia
	c) Vibrio cholerae		d) Shigella dysenteriae

Q.3	A group of scientists studying the melting glaciers in Antarctica discovered ancient air bubbles trapped within the ice. Analysing these bubbles, they find significantly lower concentrations of carbon dioxide compared to the present atmosphere. This information suggests that:
	a) Human activities have significantly increased the concentration of carbon dioxide in the atmosphere.		b) The current levels of carbon dioxide are within the natural range of variation for Earth's climate.
	c) The melting glaciers are a major source of carbon dioxide emissions contributing to global warming.		d) Ancient civilisations had developed advanced technologies to capture and store carbon dioxide.

Q.4	Consider two restaurants: one follows a "zero food waste" policy, while the other does not. Which environmental impact is most likely to be affected by the "zero food waste" policy?

If both gases have seen a 20% rise in concentration since pre-industrial times, which of the following statements is accurate based on their effect on raising global temperatures?
	a) Nitrous oxide would have a lower warming effect due to its longer atmospheric lifetime.		b) Methane would cause more significant warming due to its higher global warming potential.
