things are made of plastic. There are some other materials. But they are not used as much as these five materials.

usually feel cool if you touch it. We use metal to make lot of things. Next let's talk
about glass. Glass is very smooth. It feels cool to touch. It is not as heavy as metal. It
is hard but it is not strong. It breaks very easily. Now let's talk about wood. Wood is
lighter than metal and glass. It is not as strong as metal. But it is much stronger than
glass. Things made from wood are usually light and hard and strong. Now let's talk
about cloth. Cloth is very light. It is much lighter than wood. And it is very soft. Now
let's talk about plastic. Plastic is also very light. But it is different from cloth.
Sometimes it is soft and some time it is hard. Plastic can be used to make thin plastic
bags. These are light, soft and strong.

Answer 2

Answer: plastic.

• Material is a tangible substance that constitutes a physical object.
• Air is not a tangible, concrete substance. It is in gaseous form and has small particles of dust in it. Thus, the air is not material.
• Water is a liquid that is used in the manufacturing of several things. However, it's not considered material as the question itself suggests.
• A window is a complete physical object. It does not go into the making of anything else. It is a final good in itself and hence not a material.
• In this context, plastic is the most appropriate example of "material".
• Hence the answer is (b) plastic.
