Answer 2

Here is your answer-

Before using a substance, we need to separate harmful or non-useful substances that may  be mixed with it. Sometimes, we separate even useful components if we need to use them  separately.

Two examples when we need separation

>We used to separate slightly larger sized impurities like the pieces of dirt, stone,  and husk from wheat, rice or pulses by handpicking method.

>Rice or pulses are usually washed before cooking. When we add water to these,  the impurities like dust and soil particles get separated.
