Concept:The key is to arrange the parts in a logical chronological order: from the origin of spoken language to symbols, diversification, and finally writing systems.
Explanation:Start with sentence 1: “The evolution of language is deeply linked to human history.”
Part R logically comes next as it introduces spoken language developing alongside tool use.
Then Part P follows, describing early humans using symbols to convey meaning after spoken language.
Next, Part S explains that languages diversified over time, which naturally follows the use of symbols.
Finally, Part Q discusses writing systems, which emerged much later, leading into sentence 6 about modern evolution.
The correct sequence is R → P → S → Q.
Answer:The correct order is RPSQ, which corresponds to option C.
