Statement: It will be a substantial achievement in the field of education if one provides one school for every village in our country and enforce attendance. Assumptions: Children in villages do not attend school regularly. Providing school to every village is desirable.

Given data

• Statement: Substantial achievement if each village has a school and attendance is enforced.
• Assumption I: Children in villages do not attend school regularly.
• Assumption II: Providing a school to every village is desirable.

Concept/Approach

The claim of 'substantial achievement' relies on a need (irregular attendance) and on the desirability of the proposed provision.

Step-by-step reasoning
Enforcing attendance presumes attendance is currently irregular ⇒ I is assumed.Calling the outcome a 'substantial achievement' presumes that providing a school per village is desirable/beneficial ⇒ II is assumed.

Verification/Alternative

If attendance were already regular, 'enforce attendance' would be pointless. If a school per village were not desirable, calling it a substantial achievement would be incoherent.

Common pitfalls

• Treating 'achievement' as purely rhetorical without embedded desirability/need.

Final Answer
Both I and II are implicit.
