Q.1	In the city of Sustainia, authorities plan to reduce carbon emissions by integrating renewable energy sources. If a solar panel system installed on public buildings generates 500 kilowatt-hours (kWh) of electricity per month, how much electricity can it generate in a year, and what's its potential impact on carbon emissions if each kilowatt-hour not generated by fossil fuels reduces 0.9 pounds of Carbon dioxide emissions?
	a) 6000 kWh, reducing 5400 pounds of CO2		b) 4500 kWh, reducing 4050 pounds of CO2
	c) 5500 kWh, reducing 4950 pounds of CO2		d) 6500 kWh, reducing 5850 pounds of CO2

Q.2	Coastal regions have been experiencing a rise in sea surface temperatures due to climate change, causing concern among local communities and authorities. As part of a coastal environmental study project, your team is investigating the potential impact of this situation. Based on your research and understanding, which extreme weather event is expected to become more severe or frequent in coastal areas due to climate change ?
	a) Tornadoes		b) Hurricanes/Cyclones
	c) Snowstorms		d) Hailstorms

Q.3	A family went on a camping trip and drank water from an untreated stream. Several days later, they all became ill with vomiting and diarrhoea. Which of the following is the most likely cause of their illness? 1. Contaminated water from the stream 2. Ingestion of a parasite present in the stream water 3. A contagious respiratory illness
