Assertion Reason Analysis
Assertion (A) Analysis
The assertion states that the kneading and squeezing method is used while washing woollen garments. While gentle washing is typically recommended for wool, methods involving some level of manipulation like kneading and squeezing can occur during the washing process. These actions create friction and agitation.
Therefore, based on the provided context and the correct answer, this assertion is considered correct, implying these actions are relevant to wool washing procedures or their consequences.
Reason (R) Analysis
The reason correctly identifies the scaly structure of wool fibres. When subjected to friction, moisture, and heat (common in washing), these scales tend to lift and interlock. This process is known as felting, which causes woollen items to shrink and thicken.
This statement is a scientifically established fact about wool's properties.
Relationship Between Assertion and Reason
The friction generated by the kneading and squeezing method mentioned in Assertion (A) directly interacts with the scaly structure of wool described in Reason (R). This interaction causes the fibres to felt, leading to potential damage or shrinkage of the garments.
Thus, the reason (R) provides a clear explanation for the effect observed when the method described in Assertion (A) is applied to woollen garments.
Conclusion
Both the assertion and the reason are factually correct, and the reason effectively explains the assertion.
- Assertion (A) is correct.
- Reason (R) is correct.
- Reason (R) is the correct explanation for Assertion (A).
