AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
(i) Aluminium smelting — Mineral-based, as it uses bauxite (a mineral) as its raw material.
(ii) Silk textiles — Agro-based, as it uses silk obtained from silkworms reared on mulberry leaves (an agricultural product) as raw material.
The source passage directly lists aluminium under mineral-based and silk textile under agro-based industries. In a 1-mark question like this, simply name the category and give one clear reason (the raw material source) for each. No elaboration needed.
