Statement & Assumption — A government public-interest notice says: “For a child’s better mental health, admit him/her to school only after completing five years of age.” Which assumptions are implicit? I. A child cannot learn anything before five years of age. II. Some schools do admit children below five years of age.

Introduction / Context:The advisory prescribes a minimum age for school entry in the interest of mental health. We test which premises are necessary.

Given Data / Assumptions:

• Target behavior: delay formal admission until age 5.
• Audience: parents choosing school entry timing.

Concept / Approach:Assumption II is necessary; if no school admitted children under five, the advisory would be redundant. Assumption I is too strong; the guidance favors later formal schooling, but it does not deny all learning before five (learning can occur at home or preschool).

Step-by-Step Solution:Accept II: Policy presumes an existing practice of earlier admissions.Reject I: “Better mental health” rationale does not entail zero learning earlier.

Why Other Options Are Wrong:“Either” overreaches; “Neither” ignores the advisory’s practical target.

Final Answer:if only Assumption II is implicit
