Q.1	In a small town, the local government implemented a waste reduction program. They observed a decrease in greenhouse gas emissions over the years. To what extent do dietary choices contribute to this positive change?
	a) No impact, as waste reduction is solely related to recycling efforts.		b) Significant impact, as certain food choices can result in lower carbon emissions.
	c) Negligible impact, as emissions are primarily influenced by industrial activities.		d) Unrelated impact, as the waste reduction program focuses on non-food waste.

Q.2	You've been tasked with managing a community composting project. Over a period of 20 days, you monitored the temperature changes within the compost pile. Based on the data depicted in the graph below, what could be the likely reason behind the observed fluctuations in temperature throughout the composting process?
	a) Insufficient aeration leading to anaerobic conditions and temperature fluctuations.		b) Adequate moisture levels causing microbial activity and temperature rise.
	c) Lack of moisture causing temperature variations as the decomposition process slows down.		d) Lack of compostable materials resulting in temperature fluctuations due to microbial imbalance.

Q.3	A research team investigated the effects of climate change on the migration patterns of marine species. What implications can changing migration patterns have on marine ecosystems, and how might this impact human communities reliant on these species for sustenance?
	a) Altered migration patterns might disrupt food chains, affecting species abundance and diversity in marine ecosystems		b) Changing migration patterns will have no significant impact on marine ecosystems
	c) Human communities relying on these species can easily adapt to changes in migration patterns		d) Altered migration patterns will lead to increased catch and abundance of marine species, benefiting human communities

Q.4	Which practice aligns with the goal of "recycling" household waste?
	a) Throwing away mixed materials in one bin.		b) Composting organic waste separately.
	c) Discarding electronics with regular trash.		d) Mixing paper and plastic in the recycling bin.

Q.5	Consider the following scenario and choose the correct option. Scenario: You're a college student living in a shared hostel room with two other roommates. You've noticed increased common illnesses among your roommates, like colds, flu, and stomach upsets. You suspect poor hygiene might be playing a role. Instructions: Choose the MOST LIKELY way your hygiene habits could contribute to your roommates' health problems, and explain your reasoning.
