Q.1	Researchers conducted an experiment to evaluate the impact of controlled burning on grassland ecosystems. The results indicate an increase in plant diversity post-burn. What is the likely reason for this observation?
	a) Controlled burns reduce soil fertility, promoting diverse plant species.		b) Controlled burns remove invasive species, encouraging native plant diversity.
	c) Controlled burns eliminate all vegetation, allowing invasive species to dominate.		d) Controlled burns clear space for monoculture growth.

Q.2	Researchers conducted an experiment to assess the impact of ocean acidification on marine snail populations. They exposed snails to different pH levels in controlled environments and measured their growth rates over time. The graph below illustrates the relationship between pH levels, carbonate ion concentration. Based on this data, what is the probable outcome for marine snail populations as the H+ increases in the seawater?
	a) Snails will exhibit accelerated shell growth due to higher calcium carbonate availability.		b) Snails will exhibit reduced shell growth and vulnerability to shell dissolution.
	c) Snails will show no change in growth rates regardless of pH variations.		d) Snails will develop stronger, thicker shells to withstand changing pH conditions.

Q.3	As a responsible homeowner, you are considering installing a smart thermostat to control your home's heating and cooling system. You are aware of the potential benefits of smart thermostats, such as energy savings and improved comfort. However, you are also hesitant to make the switch due to concerns about cost and complexity. Which of the following benefits would NOT incentivise you to install a smart thermostat?
	a) Reduced energy consumption and lower utility bills		b) Ability to receive real-time energy usage data
	c) Increased complexity in operating the heating and cooling system		d) Remote access and control from anywhere using a smartphone or tablet

Q.4	Consider the case study given below and answer the following question: Case Study: The Green Guardians of Greenhill High Greenhill High, a bustling school with over 1,000 students, faced a rising energy bill and growing concerns about its environmental impact. The principal and teachers knew they needed a change, and thus, the "Green Guardians" were born! This student-led initiative focused on three key areas: energy-efficient appliances, LED lighting, and well-insulation. Appliance Upgrade: The Green Guardians convinced the school board to replace ageing appliances with ENERGY STAR certified models. New washing machines used cold water effectively, while newer dishwashers boasted shorter cycles and automatic shut-offs. These changes resulted in a 20% reduction in kitchen and laundry energy consumption. Lighting the Way: Replacing traditional incandescent bulbs with LED lights was a game-changer. These LED bulbs lasted 25 times longer, used 80% less energy, and provided brighter, cooler light. Not only did the classrooms become more comfortable, but the school also saved 15% on its lighting costs. Insulating for Impact: The Green Guardians knew that keeping the school warm in winter and cool in summer would significantly reduce energy use. They proposed adding insulation to the attic and walls, sealing air leaks, and upgrading windows. The results showed a 10% drop in heating and cooling energy needs, creating a more comfortable and sustainable learning environment. The Green Guardians' efforts didn't stop there. They launched awareness campaigns, organised energy-saving competitions, and even convinced the cafeteria to source local, organic food. Their success story inspired other schools to join the green movement, proving that even small changes can make a big difference. The case study mentions the Green Guardians' focus on local, organic food. How does this relate to the concept of clean and affordable energy? 1. Reducing transportation emissions associated with food distribution. 2. Supporting agricultural practices that maximise energy use. 3. Encouraging healthy eating habits, leading to increased energy levels.
