Q.1	In your research on marine ecosystems, you've found evidence suggesting shifts in the distribution of certain fish species. Fish that were once abundant in cooler waters are now migrating to different regions. What is the primary factor influencing this phenomenon?
	a) Changes in ocean salinity		b) Reduced predation in the new habitats
	c) Increasing acidity in the oceans		d) Rising ocean temperatures

Q.2	In the quest for cost-effective, safe, and carbon-neutral energy sources, various technological options have been under scrutiny for their potential to provide a seamless transition. Among the listed energy technologies, which option is often regarded as a solution capable of enabling a smooth transition to affordable, safe, and carbon-free energy sources? 1. Natural gas 2. Biomass energy 3. Solar energy
	a) Only 2 and 3		b) Only 2
	c) Only 3		d) 1, 2 and 3

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	Emma's family discussed ways to reduce their carbon footprint. Which action contributes most to mitigating climate change on a personal level?
	a) Carpooling or using public transportation		b) Buying products with excessive packaging
	c) Leaving electronic devices on standby mode		d) Using single-use plastics regularly

Q.5	Maya and Ethan observe vibrant coral reefs, but they notice patches of white, bleached skeletons amidst the colourful corals. Choose the MOST likely factor triggering coral bleaching.
	a) Increased nutrient runoff from coastal farms, promoting algal growth that smothers corals.		b) Overfishing by large trawlers, disrupting the food chain and reducing herbivores that control algae.
	c) Rising ocean temperatures exceeding corals' stress tolerance, causing them to expel vital symbiotic algae.		d) Increased water pollution from industrial waste, introducing toxic chemicals that directly harm coral tissues.

Q.6	Daniel's school initiated a project to implement bioenergy sources to reduce its carbon footprint. As part of their research, they explored various options for renewable bioenergy.
