Q.1	Imagine you're a development consultant working with a government agency in a developing country concerned about the high levels of post-harvest food losses. You're tasked with recommending the most impactful intervention based on the data provided in the graph below. Which intervention would likely yield the greatest reductions in overall food losses while maximising impact across multiple commodities?
	a) Investing in improved storage facilities at the farm level.		b) Strengthening cold chain infrastructure across the supply chain.
	c) Training retailers on proper handling and display techniques.		d) Promoting consumer awareness about food waste reduction.

Q.2	You are troubleshooting a high electricity bill and notice that even when all appliances are turned off, the energy meter is still registering a small amount of power usage. This phenomenon is known as a vampire load. What is the main reason why vampire loads occur in most appliances?
	a) Appliances are not properly grounded, which causes them to leak electricity.		b) Appliances continue to draw a small amount of power even when they are turned off.
	c) Appliances are designed to be constantly turned on, so they use more energy when they are off.		d) Appliances are not properly connected to power outlets, which causes them to malfunction.

Q.3	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.4	A tropical country experiences frequent severe weather events, including but not limited to drought, hurricanes and cyclones, due to climate change. Its current reliance on large-scale hydropower plants makes it vulnerable to these extreme weather events.
