Difficulty: Easy
Correct Answer: Only conclusion I follows
Explanation:
Introduction / Context:We are told that video libraries are thriving. We must decide which inference is justified: (I) people have a 'video craze'; (II) watching many movies via video is much cheaper than visiting cinema halls. Only what is reasonably implied by flourishing demand can be concluded.
Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
Conclusion I: Increased popularity is a reasonable inference from flourishing businesses; I follows.Conclusion II: While possibly true in many contexts, it is not stated or entailed. Thriving could result from convenience, content variety, or availability, not necessarily price alone. II does not follow.Verification / Alternative check:
Even if cinema prices fell, video libraries could still flourish due to home convenience; hence price inference is not mandatory.Why Other Options Are Wrong:
Any option accepting II over-reads the text. 'Neither' ignores a clear implication (popularity).Common Pitfalls:
Assuming a single cause (cost) for success when multiple drivers could exist.Final Answer:
Only conclusion I follows
