In villages, it is common to observe how women at home remove the husk from the grain. This method is known as: Correct Answer Winnowing

Explanation:

Winnowing:

  • This method of separating components of a mixture is called winnowing.
  • Winnowing is used to separate heavier and lighter components of a mixture by wind or by blowing air.
  • This method is commonly used by farmers to separate lighter husk particles from heavier seeds of grain.
  • In the household women also use this process for separating grain from the husk.
  • The husk particles are carried away by the wind.
  • The seeds of grain get separated and form a heap near the platform for winnowing.
  • The separated husk is used for many purposes such as fodder for cattle.

Additional InformationSieving:

  • Sieving allows the fine flour particles to pass through the holes of the sieve while the bigger impurities remain on the sieve.
  • In a flour mill, impurities like husk and stones are removed from wheat before grinding it.
  • Usually, a bagful of wheat is poured into a slanting sieve.
  • The sieving removes pieces of stones, stalk and husk that may still remain with wheat after threshing and winnowing.
  • At the construction site sieving is used to separate pebbles and stones from sand.

Handpicking:

  • This method of handpicking can be used for separating slightly larger sized impurities like pieces of dirt, stone, and husk from wheat, rice or pulses.
  • The quantity of such impurities is usually not very large.
  • In such situations, we find that handpicking is a convenient method of separating substances.

Threshing:

  • The process that is used to separate the grain from stalks etc, is threshing.
  • In this process, the stalks are beaten to free the grain seeds.
  • Sometimes, threshing is done with the help of bullocks.
  • Machines are also used to thresh large quantities of grain.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ the passage is split into four parts and named P, Q, R and S.

By contrast, the study also found a reverse gender bias in the public’s perception of business leadership: women leaders faced less flack for failures of competence than men. S.

Perhaps, slowly, we’re realizing men should be as responsible for ethical conduct as women — which means we may not be far off from considering women just as competent as men.
