The basis is like the foundation of a house. Imagine building a house with blocks. The first row of blocks you lay down is the most important because it holds everything else up. Without a strong first row, the house might fall over. So, the basis is the main part that supports everything else.
Think of the basis as the roots of a tree. The roots are buried underground and you can’t see them, but they are super important because they hold the tree in place and help it grow tall and strong. Without roots, the tree would fall over easily. So, the basis is like the roots that keep things steady and secure.
Picture a big cake. The bottom layer of the cake is the basis. It’s the part that all the other layers sit on. If the bottom layer is wobbly or weak, the whole cake might tip over. So, the basis is like that bottom layer that keeps everything balanced and in place.
