Difficulty: Easy
Correct Answer: Only III is strong
Explanation:
Introduction / Context:This item examines whether to ban aerated drinks. Strong arguments hinge on evidence and proportionality. A ban is a severe measure; it typically requires confirmed harm and lack of less-restrictive alternatives.
Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
I is weak: Risk can be reduced via information, taxation, and regulation; a ban is not the sole method.II, while important as a liberty claim, is not by itself decisive in public-health contexts where proven harms justify restrictions. As framed in general terms, it is not a strong policy determinant.III is strong: If there is no confirmed evidence of harm, a total ban lacks justification; policy should await or seek robust evidence and consider lighter measures.IV is weak: “Others do it” is not a reason; contexts differ and imitation is not evidence.Verification / Alternative check:
Public-health practice typically escalates interventions with the strength of evidence; absence of confirmed harm argues against a blanket ban.Why Other Options Are Wrong:
Options crediting I or IV rely on absolutes or bandwagon; including II overstates liberty without addressing evidence of harm.Common Pitfalls:
Confusing policy proportionality with laissez-faire; evidence remains the key determinant for a ban.Final Answer:
Only III is strong
