An administrator of the government is like a big helper who makes sure everything in the government works smoothly. Just like how your parents or teachers make sure everything runs smoothly in your home or classroom.
The administrator is usually in charge of a certain area in the government, like making sure that laws are being followed or that important papers are filed correctly. They also help make decisions on what the government should do to make things better for the people who live there.
Think of the government like a big tree with lots of branches. The administrator is like a gardener who takes care of one branch to make sure it grows strong and healthy.
So just like how your parents or teachers help you and your friends, the administrator of the government helps everyone in their area to be safe and happy.
