Accepted Answer

Introduction / Context:This problem tests your ability to detect necessary, unstated beliefs (implicit assumptions) that make a practical action sensible. A society posts a “salespersons not allowed” notice. What must the society be assuming for this act to have the intended effect? Given Data / Assumptions: Action: A prohibition notice is displayed at the society gate. Assumption I: All salespersons will voluntarily stay away. Assumption II: The gate security can enforce the rule and stop violators. Concept / Approach:An implicit assumption is required for the action to be effective. A posted rule typically relies on a combination of compliance and enforcement. However, a 100% voluntary compliance claim is too strong; realistic policies also assume some enforcement capability (e.g., a guard who can intercept violators). Step-by-Step Solution: Ask: If II were false (no enforcement at the gate), would the notice deter determined salespersons? Effectiveness would drop drastically, undermining the purpose. Hence II is necessary.Ask: If I were false (not all salespersons stay away), can the notice still work overall? Yes—some may still be deterred by the sign and others by the guard. Therefore I is not required. Verification / Alternative check: Real-world policies combine signage plus security. Rules with zero enforcement are widely ignored; thus enforcement capacity is the operative assumption. Why Other Options Are Wrong: I-only: Assumes perfect voluntary compliance—unrealistic and not necessary.Either I or II / Both: Overstate the requirement; only enforcement capability is essential.Neither: Incorrect because some enforcement assumption is required. Common Pitfalls: Confusing “helpful” with “necessary.” Voluntary compliance helps but is not required to justify posting the rule; enforcement is the key necessity. Final Answer:Only assumption II is implicit
