Answer
Correct Answer: (c), (b), (d), (a)
Explanation
Introduction / Context:Order techno-cultural eras from earliest tool materials to modern energy age.
Given Data / Assumptions:Stone Age → Metallic Age → Alloy Age → Atomic Age.
Concept / Approach:Advances progress from natural stone tools to metalworking, then alloys, then atomic science.
Step-by-Step Solution:Stone Age (c) earliest.Metallic Age (b) follows with native metals.Alloy Age (d) adds metallurgy sophistication.Atomic Age (a) modern nuclear era.
Verification / Alternative check:World history outlines reflect this arc.
Why Other Options Are Wrong:They place atomic or alloy ages before stone/metal beginnings.
Common Pitfalls:Assuming “metallic” includes alloys; alloys are a distinct, later sophistication.
Final Answer:(c), (b), (d), (a)
