Q.2	You're the sustainability coordinator for your school, tasked with analysing and improving waste management practices. To assess current methods, you gather information on various practices used by students and staff. Analyse each scenario and identify the most appropriate 5R category it falls into: Reduce, Reuse, Recycle, Repurpose, or Refuse. Scenario 1: The school cafeteria replaces single-use plastic water bottles with reusable water bottles for students to bring from home. Scenario 2: The school declines any subscription to promotional materials. Scenario 3: The school installs motion sensor lights in hallways and classrooms to minimise unnecessary energy usage. Scenario 4: The art department uses leftover fabric scraps from previous projects to create new artwork and decorations. Scenario 5: The school has separate bins for paper, cardboard, and plastic bottles.
	a) Scenario 1: Reuse Scenario 2: Refuse Scenario 3: Reduce Scenario 4: Repurpose Scenario 5: Recycle		b) Scenario 1: Repurpose Scenario 2: Refuse Scenario 3: Recycle Scenario 4: Reuse Scenario 5: Reduce
