Quaternary sector of the economy

The economy is like a big toy box with lots of kinds of toys in it. We have toys like rocks, plants, animals, and machines.

The quaternary sector of the economy is like the toy box's special section for the smartest and fanciest toys. These toys can do things that the other toys can't because they need special skills and knowledge to use them.

In the quaternary sector, people use things like computers, science, and technology to do their work. They help make new ideas, create new products, and solve problems that are too hard for other toys to figure out.

For example, the people who work in the quaternary sector might be computer programmers who write code to make a new app, scientists who study diseases to find new medicines, or engineers who design new machines to make our lives easier.

So basically, the quaternary sector is like the smart and special section of the toy box where people use their brains and skills to create new things and solve big problems.
