Statement–Assumption — “Teachers should be careful in class because some students may disturb others,” instructed the Principal. Assumptions: I. Teachers can handle such disturbances and identify the disruptive students. II. Students will welcome the Principal’s decision.

Introduction / Context:
A supervisory directive is effective only if implementers can act on it. The Principal’s instruction presumes teacher capability, not student approval.

Given Data / Assumptions:

• Goal: maintain order and learning environment.
• Means: teacher vigilance, classroom management, reporting.

Concept / Approach:
The necessary premise is that teachers can notice and address disruptions. Student “welcome” is irrelevant to the directive’s logic.

Step-by-Step Solution:
1) I is implicit: without teacher capacity to act, the instruction is futile.2) II is not necessary: the policy does not depend on student approval.

Verification / Alternative check:
School rules are enforced regardless of student enthusiasm.

Why Other Options Are Wrong:
I-only captures the operative assumption; the rest add a nonessential attitudinal claim.

Common Pitfalls:
Conflating compliance capacity with stakeholder feelings.

Final Answer:
if only assumption I is implicit.
