Two statements are given, one is labelled as Assertion (A) and the other as Reason (R):
Assertion (A) :Adopting the policy of cultural diversity is good for a nation-state.
Reason (R) : Subordinated communities will not feel alienated in such a policy.

Both (A) and (R) are true and (R) is the correct explanation for (A)

The assertion and the reason are both true, and the reason provides a correct explanation for the assertion. Cultural diversity as a policy is considered beneficial for a nation-state because it recognizes and accommodates the diversity within the population, promoting inclusivity and social harmony. The reason complements the assertion by highlighting that in such a policy, subordinated communities are less likely to feel alienated, contributing to a more cohesive and integrated society.
