Statement — “If children are to manage our world in the future, they need to be equipped to do so.”\nAssumptions:\nI. The world has always educated children.\nII. It is possible to educate and equip children.

Introduction / Context:
The conditional claim argues for present investment (education/equipment) based on a future role of children. This presupposes that such equipping is feasible; it does not rely on historical constancy.

Given Data / Assumptions:

• Statement: If children will manage the world, they must be equipped now.
• Assumption I: The world has always educated children.
• Assumption II: Equipping/educating children is possible.

Concept / Approach:
Necessity analysis: the recommendation collapses if equipping is impossible. Whether the world “has always” educated children is a historical claim, not required.

Step-by-Step Solution:
1) Identify enabling condition: feasibility of education → II.2) Historical regularity (I) is irrelevant to the present prescription.

Verification / Alternative check:
Even if there were eras without formal education, the recommendation still makes sense provided education is possible now.

Why Other Options Are Wrong:
Only I/Either/Both/Neither misstate necessity.

Common Pitfalls:
Confusing background facts with enabling conditions.

Final Answer:
Only Assumption II is implicit.
