What does the history of developed countries indicate about the shifts that have taken place between sectors?
The history of developed countries indicates a clear pattern of sectoral shifts over time. At the initial stages of development, the primary sector was the most important sector of economic activity, with most goods produced being natural products and most people employed in this sector.
Over time, as new methods of manufacturing were introduced and factories expanded, people who earlier worked on farms began working in factories. The secondary sector gradually became the most important in terms of total production and employment.
In the past 100 years, there has been a further shift from secondary to tertiary sector in developed countries. The service sector has now become the most important in terms of total production, and most working people are employed in this sector. This is the general pattern observed in developed countries.
Explanation
This question tests students' understanding of the historical pattern of sectoral shift in developed countries. The textbook clearly outlines three stages: (1) Primary sector dominance at initial stages of development, (2) Shift to secondary sector with industrialization and factory expansion, and (3) Recent shift to tertiary/service sector in the last 100 years. Students should mention all three stages with key terms like 'primary sector', 'secondary sector', 'tertiary sector', and 'service sector' to score full marks.
Solution Steps
Step 1: Identify the initial stage - primary sector was most important at early development
Step 2: Explain the first shift - from primary to secondary sector with factory expansion
Step 3: Explain the second shift - from secondary to tertiary/service sector in last 100 years
