Statement–Assumption (School Punctuality Instruction): Statement: The principal instructs: “For the coming month, all students must reach school at least 15 minutes before the usual reporting time.” Assumptions: I) Parents of students are likely to protest this instruction. II) Parents may request the principal to withdraw the instruction.

Introduction / Context:
The principal issues a punctuality directive. We must detect which hidden beliefs are indispensable for issuing such an instruction. Note that speculative reactions of third parties (parents) are not automatically assumed unless the instruction depends on anticipating them.

Given Data / Assumptions:

• Given instruction: Reach 15 minutes earlier for one month.
• Assumption I: Parents will protest.
• Assumption II: Parents may ask for withdrawal.

Concept / Approach:
An implicit assumption must be necessary. Ask: If we deny I and II (no protests/withdrawal requests), does the instruction lose logic? No—the directive is justified by school needs (e.g., assembly, safety checks, traffic management) irrespective of parental reaction predictions.

Step-by-Step Solution:
1) Identify the purpose of the instruction: improve punctuality/logistics.2) Test Assumption I: If parents do not protest, the instruction still stands; not necessary.3) Test Assumption II: If parents do not request withdrawal, the instruction still stands; not necessary.

Verification / Alternative check:
School administrations routinely issue time-bound reporting rules for examinations, drills, or events. Such directives do not presuppose opposition; they anticipate compliance. Therefore, neither I nor II underpins the instruction’s validity.

Why Other Options Are Wrong:
“Only I/Only II/Both/Either” incorrectly treat speculative parental behavior as a precondition, which it is not.

Common Pitfalls:
Confusing potential stakeholder reactions (which may or may not occur) with logical prerequisites for issuing an administrative directive.

Final Answer:
Neither Assumption I nor II is implicit.
