With reference to the sectors of the Indian economy, consider the following pairs : 1. Storage of agricultural produce - Secondary 2. Dairy farm - Primary 3. Mineral exploration - Tertiary 4. Weaving cloth - Secondary How many of the pairs given above are correctly matched ?

Gives the standard threefold classification and labels primary = agriculture, secondary = manufacturing/industry, tertiary = services.

A student can use this rule to ask whether 'storage' is closer to production (primary), transformation (secondary) or a service (tertiary).

Lists examples: primary includes agriculture, fishing, etc.; tertiary includes trade, transport, communication, banking, services—showing storage-like activities often appear among service-type examples.

Combine this with the observation that storage is a post-harvest handling activity (not production or manufacturing) to consider if it fits the tertiary/service list.

Defines secondary as activities that change natural products into other forms through manufacturing, distinguishing manufacturing from other post-harvest activities.

Use this to rule out secondary if storage does not materially transform the produce (i.e., no manufacturing).

Mentions 'setting up of cold storage facilities by the governments' as an item listed under what can be considered public investment in agriculture—linking storage infrastructure with agricultural policy.

A student could interpret cold storage provision as either agriculture-related public investment (link to primary) or as an infrastructural/service input (link to tertiary) and seek further classification based on whether the activity is treated as service provision.

Contains an exercise to classify occupations (e.g., courier, milk vendor) into primary/secondary/tertiary, suggesting classification is often based on function (production vs. processing vs. service/transfer).

Apply the same functional test to 'storage' — is it production, processing, or a service supporting distribution — to judge its sectoral placement.
