Statement A: Leaf plates are safer than plastic plates. Statement B: Plastic particles may enter food.

Here are the solutions to the problems:

25. Statement A: Leaf plates are safer than plastic plates. Statement B: Plastic particles may enter food.

• Statement A is correct. Leaf plates are biodegradable and do not leach harmful chemicals into food, making them safer than plastic plates.
• Statement B is correct. Plastic plates, especially when heated or scratched, can release microplastic particles into food.

Therefore, both statements are correct.

The correct option is 3) Both statements are correct.

26. Match the worker to food process:

• A. Farmers: Are involved in Growing grains. (A-1)
• B. Agricultural labourers: Are involved in Helping in fields. (B-2)
• C. Millers: Are involved in Processing grains. (C-3)
• D. Vendors: Are involved in Selling grains. (D-4)

So the correct matching order for A, B, C, D is 1, 2, 3, 4.

The correct option is 1) 1, 2, 3, 4.

27. A village receives less rainfall one year. Which water source will be affected first?

A village tank is a surface water body that collects rainwater. If there is less rainfall, the water level in the village tank will drop significantly and quickly, affecting it first. Underground metro water is not a typical village water source, seawater is not directly affected by local rainfall, and taps are just distribution points.

The correct option is 3) Village tank.

28. A water drop falls from cloud to river. Which sequence is correct?

The natural sequence for a water drop falling from a cloud and reaching a river is precipitation (rain) from the cloud, which then flows into the river.

The correct option is 2) Cloud → Rain → River.

29. Statement A: Water from purification plant goes into overhead tanks. Statement B: Overhead tanks supply clean water to houses.

• Statement A is correct. Water is purified and then often pumped into overhead tanks for storage and distribution.
• Statement B is correct. Overhead tanks are designed to store and supply clean water to houses through a distribution network.

Therefore, both statements are correct.

The correct option is 3) Both statements are correct.

30. Match tank part:

• A. Bund: A bund is an embankment that forms the Boundary of tank. (A-1)
• B. Canal: A canal is a channel that serves as a Pathway for water. (B-2)
• C. Outlet: An outlet is a point from which water is released, often for Excess water release. (C-3)
• D. Catchment area: This is the area from which rain flows into tank. (D-4)

So the correct matching order for A, B, C, D is 1, 2, 3, 4.

The correct option is 1) 1, 2, 3, 4.

31. Spongy stems help aquatic plants:

Aquatic plants often have spongy stems containing air spaces (aerenchyma). These air spaces provide buoyancy, helping the plants to Float on water.

The correct option is 3) Float on water.
