Q.1	At a science camp, Mia learns about solar energy. She analyses data and finds that a solar panel generates an average of 1.5 kilowatt-hours (kWh) of electricity per day. If a household uses 6 kWh of electricity daily, how many solar panels would they need to cover their entire daily energy consumption?
	a) 2 solar panels		b) 3 solar panels
	c) 4 solar panels		d) 5 solar panels

Q.2	In a coastal city, students investigated the impact of nutrient runoff on marine ecosystems. They discovered that agricultural practices contributed to excess nutrients reaching the ocean. How do nutrient runoff and eutrophication affect marine life?
	a) Nutrient runoff causes algal blooms, leading to oxygen depletion and harming marine life.		b) Nutrient runoff benefits marine plants, enhancing their growth and diversity.
	c) Eutrophication leads to increased oxygen levels, supporting marine species.		d) Introducing more fishing activities can balance the effects of nutrient runoff.

Q.3	During a marine conservation seminar, a panel discusses the diverse range of threats posed by ocean plastics to marine life. They emphasise the severe consequences and challenges faced by various species due to plastic pollution in oceans. Which scenario best illustrates the impact of discarded plastic on marine life?
	a) Volunteers find intact plastic bottles floating near a reef, causing minor obstructions to fish.		b) Discarded fishing nets entangle sea turtles, causing injuries and hindering their swimming.
	c) Seabirds consume small plastic debris, with unclear effects on their health.		d) Marine biologists locate scattered plastic bags on the ocean floor with minimal impact on organisms.

Q.4	Sarah is a teacher at an elementary school. She collects scrap paper from her students and uses the blank sides for drawing, thereby extending the life of the paper before recycling it. What is Sarah doing in this scenario to contribute to waste reduction and sustainability?
	a) Throwing scrap paper away		b) Promoting the use of new paper
	c) Reusing paper before recycling it		d) Increasing paper waste

Q.5	The government of a city wants to switch to renewable energy sources to help the environment. Which of the following strategies could the city use to promote renewable energy adoption and reduce environmental impact?
