Q.1	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.2	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.3	In a study comparing two diverse regions, a Coastal City and a Desert Region, several factors influencing annual rainfall were analysed and recorded in the table below. Based on this information, which of the following statements is most accurate?
	a) The coastal city experiences high evaporation rates due to its proximity to the ocean, leading to increased rainfall.		b) The desert region receives less rainfall because the water cycle doesn't operate there.
	c) The coastal city receives more rainfall because it has more vegetation to trap moisture.		d) The desert region gets less rainfall because the water cycle is more active over the ocean.

Q.4	In the following question, you will find an assertion and a reason. Select the appropriate option that applies. Assertion: While deserts like the Sahara are notoriously arid, some coastal regions also experience water scarcity. Reason: Rising sea levels due to climate change can contaminate freshwater sources with saltwater intrusion.
	a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.		b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
	c) The assertion is true, but the reason is false.		d) The assertion is false, but the reason is true.
