Q.1	Nick installed a solar panel system on his rooftop to harness solar energy for his home. He wants to understand the practical process behind solar energy generation. Help him understand what happens when photons from sunlight strike the photovoltaic cells in a solar panel system.
	a) They generate heat energy for space heating.		b) They release electrons, creating an electric current to power appliances.
	c) They produce hydrogen gas for fuel cells.		d) They heat up a storage tank of water for domestic use.

Q.2	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.3	Robert, an environmentally conscious individual, has recently initiated a practice of composting her food scraps and yard trimmings. He intends to utilise the resultant compost as soil enrichment for her garden beds, aiming to reduce dependency on commercial fertilisers and promote sustainable gardening practices.
