Historical technology sequence (earliest to latest): On arranging Stone Age, Metallic Age, Alloy Age, Atomic Age chronologically, which occupies the 3rd position?

Introduction / Context:
Civilizational timelines often appear in reasoning exams. Here you must place broad technological eras in order and identify the one at the third position.

Given Data / Assumptions:

• Sequence to order: Stone Age → Metallic Age → Alloy Age → Atomic Age.
• Assume the conventional progression from earliest lithic tools to modern nuclear era.

Concept / Approach:
Start with Stone Age (prehistoric lithic tools), followed by the adoption of simple metals (copper/bronze/iron). As metallurgy advances, deliberate alloying becomes systematic. The Atomic Age represents the most modern period.

Step-by-Step Solution:

Verification / Alternative check:
Cross-check with history of technology: lithic → metal → alloys → nuclear. The third slot is Alloy Age.

Why Other Options Are Wrong:
The other ages belong to positions 1, 2, or 4, not 3.

Common Pitfalls:
Confusing “Metallic Age” with “Alloy Age”; assuming alloys precede single-metal utilization.

Final Answer:
Alloy Age
