Which of the following sectors is primarily concerned with extracting raw materials?

The primary sector is concerned with extracting raw materials from the earth or natural environment. This sector includes activities such as agriculture, mining, forestry, and fishing, where businesses directly obtain resources that can be used as inputs for other sectors of the economy. The primary sector is fundamental because it provides the raw materials that are essential for production and manufacturing processes in the secondary sector, which involves transforming these raw materials into finished goods.

In contrast, the secondary sector focuses on manufacturing and construction, taking the raw materials sourced from the primary sector to create products. The tertiary sector is centered on providing services rather than goods, such as retail, hospitality, and healthcare. The quaternary sector represents knowledge-based activities involving services such as research and development, financial services, and information technology, which typically require specialized skills. Therefore, the primary sector stands out as the one specifically dedicated to extraction.
