Answer
Correct Answer: d, c, e, a, b
Explanation
Introduction / Context:This sequencing question checks everyday process knowledge from extraction to finished goods in metallurgy and jewellery making.
Given Data / Assumptions:
- d = Mine (place of extraction)
- c = Ore (raw mineral-bearing rock)
- e = Process (crushing, concentration, smelting/refining)
- a = Gold (refined metal)
- b = Ornaments (finished jewellery)
Concept / Approach:Follow the industrial chain: source → raw material → processing → refined metal → finished product.
Step-by-Step Solution:1) Start at the Mine (d).2) Extract Ore (c).3) Process/refine (e).4) Obtain Gold (a).5) Craft Ornaments (b).
Verification / Alternative check:This mirrors standard mineral processing and fabrication sequences used worldwide.
Why Other Options Are Wrong:
- Sequences that place ornaments before refining ignore manufacturing reality.
- Starting from ore before mine breaks causal location-to-material logic.
Common Pitfalls:Confusing ore (raw) with refined gold (metallic element), or assuming processing happens after ornaments.
Final Answer:d, c, e, a, b
