Answer 2

Drains get blocked by PLASTICS and TOILETRIES.

Explanation:

• Plastics and toiletries are often put into drains or flushed off after we use them.
• These substances slowly build up at narrow drains which eventually block these drains.
• This leads to the failure in drainage system and water starts to get collected in the drains.
• In case of slight rains, areas become waterlogged.
• This is reason we should stop flushing toiletries into our drains and start using proper dustbins for these.
