Critical Reasoning — Conclusions Statement: 'This book Z is the only book that focuses on the problem of poverty in India between 1950 and 1980.' Which conclusion(s) follow?

Introduction / Context:We are told book Z is the only one focusing on poverty in India during 1950–1980. We test: (I) there was no poverty before 1950; (II) no other book deals with poverty in India in 1950–1980. We must accept only what is directly implied by 'only book' within the specified period.

Given Data / Assumptions:

• Uniqueness claim for the period 1950–1980 (focus on poverty in India).
• Conclusion I: No poverty before 1950 (a historical claim beyond the statement).
• Conclusion II: No other book covers poverty in India for 1950–1980.

Concept / Approach:

• 'Only book' for a time window implies exclusivity relative to other books for that same window.
• It says nothing about times outside the window (before 1950), so we cannot infer I.
