School health — Should sex education be imparted in schools? Statement: Should we impart sex education in schools? Arguments: I. Yes. All the progressive nations do so. II. No. We cannot impart it in co-educational schools. III. Yes. It would reduce misunderstandings and make the younger generation physically and mentally healthier. IV. No. It will destroy moral fibre and traditional values.

Introduction / Context:
The prompt is whether schools should impart sex education. We must identify which arguments are strong in principle and evidence, not based on popularity or vague fears.

Given Data / Assumptions:

• Sex education can address myths, promote consent, and encourage safe health practices.
• Delivery can be age-appropriate and culturally sensitive within co-educational or single-sex formats.
• Appeals to “progressive nations” (I) are not, by themselves, reasons; they are appeals to popularity.

Concept / Approach:
Argument III presents a substantive benefit and is the genuinely strong point. Arguments II and IV rely on blanket assertions without mechanism. Argument I is an appeal to what others do, not why it should be done.

Step-by-Step Solution:

Verification / Alternative check:
Public health experience shows that comprehensive, age-appropriate programs correlate with better outcomes (delayed risky behavior, improved consent awareness), underscoring III.

Why Other Options Are Wrong:

• Only I, III and IV / Only II, III and IV / Only II and IV: all include weak arguments and/or omit the evaluation that I and II are weak.
• None is strong: incorrect because III is strong.

Common Pitfalls:
Confusing “how to implement” with “whether to implement.” Delivery can be tailored; that does not negate the core benefits.

Final Answer:
None of these
