Many workers are employed in the agricultural sector of developing countries because

Step 1: Analyze the question The question asks why agriculture in developing countries employs so many workers. We need the reason connected to how production is carried out.

Step 2: Explain the concept Production methods fall into two types:

• Labour-intensive: uses more labour than capital (hoes, cutlasses, manual planting and harvesting).
• Capital-intensive: uses more machinery and equipment than labour (tractors, combine harvesters).

Developing countries like Nigeria have abundant labour but scarce capital. Most farmers are smallholders who cannot afford machinery, so they rely on manual work. This is why agriculture absorbs so many workers.

Step 3: Evaluate each option

• A. Labour intensive method is mostly adopted: Correct. Manual farming needs many hands, so many workers are employed.
• B. Abnormal profits are made: Incorrect. Subsistence and small-scale farmers usually earn low returns, not abnormal profits.
• C. Wages in the sector is high: Incorrect. Agricultural wages are typically low compared with other sectors.
• D. They practice mechanized system of farming: Incorrect. Mechanization reduces the need for labour, which is the opposite of the situation described.

Step 4: Answer The correct option is A, labour intensive method is mostly adopted.

Exam tip: When you see "many workers" in a production question, think "labour-intensive". "Few workers" points to "capital-intensive" or "mechanized". Also remember that developing countries are labour-abundant and capital-scarce.
