	c) Area C		d) Area D

Q.2	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.3	Maria, a marine biologist, conducted a study in a coastal area. She noticed a decline in the population of a specific species of fish. Further research revealed that the rising ocean temperatures were affecting their breeding grounds. Which of the following best explains how increased ocean temperatures impact fish populations?
	a) Elevated temperatures facilitate better breeding conditions for fish.		b) Higher temperatures decrease predator's presence, causing a decline in fish populations.
	c) Increased ocean temperatures reduce oxygen levels, affecting fish reproduction.		d) Warmer temperatures encourage the migration of fish to colder regions for breeding.

Q.4	In a biology class, students are discussing the various components of the water cycle. How does transpiration contribute to this natural process?
	a) It adds water vapour to the atmosphere from plant leaves.		b) It causes rainfall directly.
	c) It prevents the water cycle from functioning.		d) It decreases the humidity in the atmosphere.

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.
	a) You always shower after gym class, but you only wash your hands before eating.		b) You keep your laundry hamper overflowing with dirty clothes for days before washing them.
	c) You clean your desk surface regularly, but you rarely disinfect your phone or laptop keyboard.		d) You use a common towel to dry your hands after washing them in the shared bathroom.

Q.6	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

During their research, the scientists observed a correlation between land-based environments and the overall health of marine ecosystems. Choose an appropriate option that best reflects the importance of terrestrial ecosystems for marine life.
	a) Land-based environments have minimal impact on marine ecosystems, thus their significance is negligible.		b) Terrestrial environments act as a buffer, filtering pollutants before they reach the oceans, thus preserving marine habitats.
