Understanding the Methods of Separation
The methods of separation mentioned—Winnowing, Threshing, and Sieving—are commonly used in agriculture and food processing. Let's break down each method to understand their requirements.
Winnowing
- Definition: Winnowing is a process used to separate grain from chaff.
- Air Requirement: This method involves using wind or air to blow away the lighter chaff, leaving the heavier grains behind. Therefore, air is crucial for this process.
Threshing
- Definition: Threshing is the method of separating the edible part of the grain from the husks.
- Air Requirement: While threshing primarily involves mechanical action (like beating), it may also involve air when done using specific machines. Thus, air can be involved but is not always necessary.
Sieving
- Definition: Sieving is used to separate smaller particles from larger ones using a mesh or net.
- Air Requirement: This method does not require air. It relies on the physical action of shaking or moving the sieve, allowing smaller particles to pass through while larger ones remain.
Conclusion
Based on the explanations above, the only method of separation that does not require air is Sieving (Z). Hence, the correct answer to the question is option B: Only Z.
In summary:
- Winnowing (X): Requires air.
- Threshing (Y): May involve air.
- Sieving (Z): Does not require air.
This understanding clarifies why option B is the correct answer in the context of separation methods.

Community Answer
Given below are some methods of separation.X - Winnowing Y - Threshing...
- X - Winnowing: This method uses the weight difference between components and depends on air to separate lighter particles (like husk) from heavier ones (like grains). Requires air.
- Y - Threshing: This method involves beating or mechanical action to separate grains from stalks. It does not rely on air for separation. Does not require air.
- Z - Sieving: This method involves passing a mixture through a sieve with appropriate-sized holes to separate particles based on size. It does not rely on air. Does not require air.
Correct Answer: b) Only Y, Z
