Q.1	Sarah and Jake embarked on a fun adventure to explore a nearby wind farm. They were fascinated by the massive wind turbines spinning gracefully in the wind. What is the primary function of these wind turbines?
	a) Capturing wind energy to create artificial rainfall in the area.		b) Filtering air pollutants to make the environment cleaner.
	c) Using wind power to pump water from underground reservoirs.		d) Generating electricity by using wind to turn turbines connected to generators.

Q.2	Why are oceans considered the "lungs of the Earth"?
	a) Because they produce a significant portion of the world's oxygen through phytoplankton photosynthesis		b) Because they are a source of clean air for the planet
	c) Because they release carbon dioxide into the atmosphere		d) Because they help in the transportation of oxygen to land-based ecosystems

Q.3	Your village receives heavy rainfall during the monsoon months of July and August as shown in the graph below. However, the remaining months experience significantly less rainfall, leading to water scarcity during the dry season. What would be the most effective strategy to address this water scarcity issue? 1. Plant more trees throughout the village to increase overall rainfall. 2. Implement rainwater harvesting systems on every household rooftop. 3. Educate villagers about water conservation practices and rainwater harvesting techniques.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.4	A tourist is exploring a kelp forest. What is the primary benefit of kelp forests in the marine ecosystem?
	a) Kelp forests have no impact on providing food and shelter for various marine species		b) Kelp forests do not assist in absorbing excess carbon dioxide from the atmosphere
	c) Kelp forests have no connection to maintaining the balance of marine food webs		d) Kelp forests provide habitats for numerous marine organisms and contribute to nutrient cycling

Q.5	In a coastal town, residents have noticed a significant increase in the intensity and frequency of storms and hurricanes over the past few years. What could be linked to the observed stronger and more frequent storms and hurricanes?
	a) Declining sea levels providing more energy for storm systems.		b) Warmer ocean waters intensifying storm development.
	c) Decline in global population density.		d) Reduced levels of atmospheric humidity.

Q.6	At a bustling street market, Orry and Sara dig into delicious street food. Sara washes her hands with tap water provided by the vendor, while Orry opts for a quick wipe with a tissue provided by his friend. Who is more likely to experience foodborne illness, and why?
	a) Sara, because tap water in crowded places might be contaminated.		b) Orry, because tissues are ineffective against grease and foodborne bacteria.
	c) Both, as neither tap water nor tissues, provide sufficient protection against foodborne bacteria.		d) Neither, because the street food was probably freshly prepared and hygienic.

Q.7	During one of their hikes, the friends encountered a variety of wildlife, including polar bears and penguins that seemed displaced. What could be a likely reason for these animals to be found far away from their natural habitats?
