Which of the following is not an example of a primary sector industry?

Appeared in: DSSSB - 29 August 2019 (Shift-1)

Explanation

Light manufacturing is an activity of the secondary sector of the economy.
The secondary sector is defined by the processing of raw materials (obtained by the primary sector) into finished or semi-finished goods.
This includes activities like textile production, car manufacturing, and electronics assembly, which transform materials rather than extracting them.

Option A: Farming (agriculture) is a core activity of the primary sector, as it involves cultivating land and growing crops, which are raw materials.
Option B: Logging (forestry) is a primary sector industry because it involves harvesting a natural resource (timber) directly from the environment.
Option C: Mining is a classic primary sector industry focused on extracting minerals, metals, and other geological materials from the earth.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of economic activities into primary, secondary, and tertiary sectors as background academic context rather than a clinical decision trigger.
This is a general knowledge question. Understanding economic structures is important for general awareness as a well-rounded professional.
The economic profile of a region (e.g., heavily industrial vs. agricultural) can influence public health trends, occupational hazards, and the types of health services needed by the community.
A country's stage of development is often linked to the dominance of these sectors, moving from primary to secondary and then to tertiary, which impacts national funding for healthcare and education.

How to Approach the Question

First, identify the negative keyword 'not' in the question. This signals that you must find the option that is an exception.
Next, define the key concept: 'primary sector industry'. Recall or deduce that this sector involves the extraction and harvesting of raw materials directly from nature.
Systematically evaluate each option against this definition.
Analyze 'Farming': It involves growing crops from the earth. This fits the definition.
Analyze 'Logging': It involves cutting down trees for wood. This fits the definition.
Analyze 'Mining': It involves extracting minerals from the ground. This fits the definition.

Concept Tested & Keywords

Concept Tested: Classification of economic activities into primary, secondary, and tertiary sectors.
Stem keywords: primary sector, industry, example
