• 3, 1, 2 and 4

• 2, 4, 3 and 1

• 4, 2, 1 and 3

Answer 1

3, 1, 2 and 4

Explanation:

Here's what each structure represents in the context of rooftop rainwater harvesting:

• Catchment area (3): This is the surface area (typically rooftops) from which rainwater is collected.
• Conduit (1): This includes gutters and pipes that collect rainwater from the catchment area and transport it.
• Recharge structure (2): This can include pits, trenches, or recharge wells where rainwater is directed to recharge groundwater or diverted to storage.
• Storage tank (4): This is where rainwater is stored for later use.
