Concept:Assertion-Reason questions test your ability to judge both the truth of each statement and the logical connection between them.
Explanation:The Assertion (A) is true because traditional Social Science teaching often presents facts about distant societies and periods without linking them to a child's own real-world surroundings.
The Reason (R) is also true — NCF-2005 based texts transformed Social Science by replacing rote fact-memorization with inquiry-based learning, which is indeed a strength.
However, (R) does not explain (A). The reason talks about a positive reform (NCF-2005’s approach), while the assertion points out a weakness of older methods.
For (R) to be the correct explanation of (A), it would need to directly justify why conventional teaching ignores children’s experiences. Instead, (R) describes a separate, newer improvement.
Thus, both statements are independently true, but (R) is not a cause or explanation for (A).
Answer:Both (A) and (R) are true but (R) is not the correct explanation of (A). Hence, the correct option is B.
