Concept:
Belgium is a country with diverse linguistic and cultural communities, mainly the Dutch-speaking, French-speaking, and German-speaking populations. To maintain peace and stability, Belgium adopted a system of power sharing that accommodated these differences.
Step 1: {\color{red}Analyze the Assertion (A).}
Belgium introduced a unique power-sharing arrangement to address conflicts among different linguistic groups. This system ensured equal representation and participation of different communities in governance.
Therefore, Assertion (A) is true.
Step 2: {\color{red}Analyze the Reason (R).}
Belgian leaders understood that their country had significant linguistic and cultural diversity. Recognizing these differences helped them design a political system that would fairly represent all communities.
Thus, Reason (R) is also true.
Step 3: {\color{red}Determine the relationship between (A) and (R).}
The recognition of regional and cultural differences by Belgian leaders led them to create a power-sharing system that could accommodate these divisions.
Hence, Reason (R) correctly explains Assertion (A).
