A country is described as industrialized if

Step 1: Analyze the question The question asks what makes a country "industrialized." We need the option that best describes the economic structure of an industrialized country.

Step 2: Explain the concept An industrialized country is one where manufacturing and other industrial activities form a large part of the economy. The key signs are:

• Industry (especially manufacturing) contributes a large share of GDP or national income.
• A large share of the workforce is employed in industry.
• Mass production, advanced technology and high output per worker.

Examples: the USA, Germany, Japan, the UK.

Step 3: Evaluate each option

• A. The contributions of industries to national income are high. Correct. This is the standard measure of industrialization, since a high industrial share of national income shows that industry drives the economy.
• B. Traditional and modern sectors coexist. This describes a dual economy, typical of developing countries, not an industrialized one.
• C. The country adopts an import promotion strategy. Industrialization strategies usually involve import substitution or export promotion. "Import promotion" would not make a country industrialized.
• D. Primary industries dominate the economy. Primary industries (farming, fishing, mining) dominating an economy indicates an agrarian or underdeveloped economy, the opposite of industrialized.

Step 4: Answer The correct option is A.

Step 5: Exam tip For "industrialized" questions, think "industry's share of national income/output is high." Link the other options to their own terms:

• Traditional + modern together = dual economy
• Primary sector dominance = agrarian/developing economy
• Replacing imports with local production = import substitution
