All economic activities namely primary, secondary, tertiary and quaternary, revolve around obtaining and utilising resources necessary for survival. Secondary activities add value to natural resources by transforming raw materials into valuable products. Cotton in the boll has limited use but after it is transformed into yarn, becomes more valuable and can be used for making clothes. Iron ore, cannot be used; directly from the mines, but after being converted into steel it gets its value and can be used for making many valuable machines, tools, etc. The same is true of most of the materials from the farm, forest, mine and the sea. Secondary activities, therefore, are concerned with manufacturing, processing and construction (infrastructure) industries.

Which of the following is NOT true about economic activities ?

Secondary activities deal with service sector

The correct answer is option 3: Secondary activities deal with service sector

Option 3: Secondary activities deal with service sector. This is incorrect. Secondary activities involve processing and manufacturing, where value is added to raw materials. The service sector belongs to tertiary activities, not secondary activities.

Option 1: It includes all the activities which generate income. This is true because economic activities are undertaken to earn income or livelihood.

Option 2: Primary activities generate income by extracting natural resources. This is true. Activities such as agriculture, mining, fishing, and forestry involve extraction and use of natural resources.

Option 4: Value addition is done in secondary activities. This is true because secondary activities convert raw materials into finished or semi-finished products.
