Statement & Assumption — “So long as society remains caste-based, there is no harm in having caste-based organisations to look after caste welfare.” Which assumptions are implicit? I. There is nothing wrong with religious organisations spreading their ideals. II. Political parties cannot look after caste welfare as well as caste-based organisations can.

Introduction / Context:
The claim is narrowly framed: the existence of caste-based organisations is “no harm” so long as caste persists. It neither comments on religious bodies nor compares efficacy with political parties.

Concept / Approach:
Assumption I is about religion, a different axis. Assumption II asserts comparative incompetence of parties—an added thesis the statement does not require. The minimal premise is simply that where social structure is caste-based, having organisations aligned to that structure is not inherently harmful; this does not entail I or II.

Final Answer:
Neither I nor II is implicit.
