Efficiency of labour in a country is determined by the following factor except the

1. Analyze the question The question asks which option is NOT a factor that determines the efficiency of labour. Efficiency of labour means how productive each worker is, that is, the output per worker.

2. Explain the concept Efficiency (productivity) of labour depends on the quality of workers and their working environment, not on how many workers there are. Key determinants include:

• Education and training: skills and knowledge raise output per worker.
• Health and nutrition: healthy workers work better.
• Working conditions: safe, comfortable workplaces, fair pay, and good incentives motivate workers.
• Social attitude to work: a culture that values hard work and discipline improves productivity.
• Tools and technology available to workers.
• Quality of management and supervision.

By contrast, total population affects the size or quantity of labour supply, not its efficiency.

3. Solution, option by option

• A. Social attitude to work: affects willingness and discipline, so it is a determinant.
• B. Education and training: builds skills, so it is a determinant.
• C. Working conditions of workers: affects morale and output, so it is a determinant.
• D. Total population: determines how many people are available, not how productive each one is. It is not a determinant of efficiency.

4. Answer The exception is D. total population.

5. Exam tip Separate quantity from quality. Population size, labour force size, and working hours concern the quantity of labour. Education, training, health, attitude, and working conditions concern the quality (efficiency) of labour. When you see "except" questions, find the option that belongs to the other group.
