SSC CGL 2025 Tier-I · 16 September 2025, Shift 2 · General Intelligence and Reasoning · Question 11 of 100

We transcribed this text from the pictures on a candidate's response sheet for this shift; the answer is the key SSC colour-marked on that sheet. Solution last reviewed 13 September 2026.

Where this paper and its answers come from

SSC does not publish CGL question papers or a public answer key. From 2025 the candidate response sheet prints every question and option as a picture, so the text here is transcribed from those pictures for this shift and checked against them independently; where the layout carries meaning, the picture is shown as well. Each answer is the key SSC colour-marked on that sheet. SSC released a tentative key for challenge and later its final one, both only to candidates behind a login, and the sheet does not say which of the two it carries. The solutions are written by UnlockIAS.

Arrange the following in chronological order (Based on Age/History): 1. Industrial Revolution 2. Bronze Age 3. Information Age 4. Iron Age 5. Stone Age

(a)5, 2, 4, 1, 3
(b)2, 4, 5, 1, 3
(c)5, 4, 2, 1, 3
(d)1, 2, 3, 4, 5

Answer

Why

Correct — A.
Rule: tools went stone → bronze → iron, and the industrial and information eras come much later.

Stone Age (5)
Bronze Age (2): copper alloyed with tin
Iron Age (4)
Industrial Revolution (1), then Information Age (3)

5, 2, 4, 1, 3 → option (a).

Why the others are wrong

(b)
2, 4, 5, 1, 3 — 2, 4, 5 puts the Stone Age after the Bronze and Iron Ages. Stone tools came first, and metal working came after them.
(c)
5, 4, 2, 1, 3 — 5, 4, 2 swaps the two metal ages. Bronze came before iron, which is why the order runs Stone, Bronze, Iron.
(d)
1, 2, 3, 4, 5 — 1, 2, 3, 4, 5 is just the printed order of the list. It opens with the Industrial Revolution, the second-latest of the five.

Concept

Chronological ordering asks for the sequence in time, not the order printed. Split the list into two groups: the prehistoric ages, named for the main material of tools, and the modern eras.

The prehistoric ages run Stone, Bronze, Iron. The Industrial Revolution, which began in 18th-century Britain, comes next, and the Information Age of computers and the internet comes last.

The dates of these ages differ from region to region, which is why the question asks only for their order.

Key facts

The three-age system orders prehistory as Stone Age, Bronze Age, Iron Age.
Bronze is an alloy of copper and tin.
The Industrial Revolution began in Britain in the 18th century.
The Information Age is the era of computers and the internet, from the late 20th century.

Common traps

Swapping the Bronze and Iron Ages, which is the order option (c) offers
Answering in the printed order of the list

Here SSC gives five labelled periods and asks for their order in time. The options differ in where the three prehistoric ages sit and whether the list's printed order is kept.
