The correct option is B - 2 and 3.
[as per provisional answerkey]Why this is correct
The passage provides specific details regarding the convergence theory and its application across different economic eras. Let us evaluate the statements based on the text:
- Statement 2: The passage explicitly states, "The process by which countries close their labour-productivity gap with the technology leader is based on convergence theory." This confirms that the closing of the gap between labour and productivity is the central theme of the theory.
- Statement 3: The passage describes technology leaders as those who experience a rise in per capita income during the "breakaway phase" while followers remain unchanged. It lists leaders (e.g., Western Europe and North America) and notes that followers "adopt the new technology" later during the catch-up phase. This implies that leaders arrive at these economic eras earlier than followers.
Why the other options are incorrect
- Statement 1 - The convergence model divides nations into three phases: This is a subtle misinterpretation. The passage states the model "divides economic eras into three phases" and "divides economic entities into two categories" (leaders and followers). It does not divide the nations themselves into three phases.
- Statement 4 - The time period encompasses 4,012,200 years: This is a mathematical error based on a literal summation of the dates mentioned. The passage mentions distinct starting points for technologies (3 MYA, 1 MYA, 12,000 years ago, and 200 years ago). These are overlapping or nested timelines within human history, not a cumulative sum of years. Furthermore, "3 million years ago" already encompasses the subsequent dates mentioned.
- Option (a) - 2 and 4: Incorrect because Statement 4 is logically and mathematically flawed based on the context of historical timelines.
- Option (c) - 3 only: Incorrect because it ignores Statement 2, which is directly supported by the opening sentence of the passage.
- Option (d) - 1, 3 and 4: Incorrect because it includes Statement 1 (misclassification of phases) and Statement 4 (incorrect temporal calculation).
Key Concept
Critical reading and precise attribute association: distinguishing between how a theory categorizes "eras" versus "entities" and identifying the core objective of a stated economic model.
