Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Sieving is a method in which fine particles are sieved through holes of the sieve while the bigger impurities remain on the sieve. Sieving is used in a flour mill to separate impurities like husk and stones from wheat before grinding it. It is also used at construction sites to separate pebbles and stones from sand.
