In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts - P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
1. The evolution of language is deeply linked to human history.
P: Early humans used symbols to convey meaning.
Q: Writing systems emerged thousands of years later.
R: Spoken language likely developed alongside tool use.
S: Over time, languages diversified across regions.
6. Today, language continues to evolve with technology.

Correct option is C

Option (c) is the correct order of the given sentences: R P S Q.
Why this order works (bullet explanation):
· R first: Chronological foundation — spoken language emerging with early tool use is the most primitive stage, so R logically opens the sequence after the general statement (1).
· P next: After speech, early humans progressed to symbols (gestures/marks) as proto-communication/pre-writing devices, which naturally follows the origin of speech.
· S then: With communities spreading and interacting differently, languages diversified over time; S generalizes the long historical drift after early development.
· Q last: Writing systems emerged thousands of years later — a late, well-defined milestone that smoothly precedes the modern note in sentence 6 about evolution with technology.
· The adverbials “ Over time” (S) and “ thousands of years later” (Q) are strong temporal signals anchoring S before Q in a long-range historical progression.
