Statement–Argument — Should people below 18 years be allowed to join the armed forces? Arguments: I) No; under-18s generally lack the physical and mental maturity to shoulder such burdens. II) Yes; earlier entry gives the country a longer-serving force. Choose the strong argument(s).

Introduction / Context:
Military service demands high physical fitness, emotional resilience, and legal capacity. Minimum-age thresholds exist to protect minors and ensure readiness.

Given Data / Assumptions:

• Most regimes place lower bounds near adulthood for combat roles.
• Training is strenuous; legal liabilities and consent are complex.
• Longer tenure alone does not offset maturity concerns.

Concept / Approach:
Argument I directly addresses suitability: maturity/readiness—core to defense effectiveness and duty of care—making it strong. Argument II prioritizes tenure length, but ignores readiness, safeguarding, and international norms; hence weak.

Step-by-Step Solution:

Verification / Alternative check:
Cadet pipelines often start pre-18 but defer enlistment until legal adulthood—reflecting I’s logic.

Why Other Options Are Wrong:
Options crediting II elevate tenure over safety/readiness.

Common Pitfalls:
Confusing earlier start with better outcomes regardless of maturity.

Final Answer:
if only argument I is strong.
