Identify the correct chronological sequence of the developers of communicative…

Concept — The history of human communication is periodised by the technologies that successively extended a message’s reach in space and time: speech, then writing, then the organised carriage of written messages, then cheap reproducible copies, and finally instantaneous electrical signalling. Each stage rests on the one before it, so a chronological ordering of the peoples who developed communicative systems follows the order in which these media capabilities first appeared — not the order in which those peoples rose to political power.

Application — Dating each people’s landmark contribution to a communicative system:

1. Sumerians, Mesopotamia, c. 3400–3100 BCE — cuneiform on clay tablets, the earliest full writing system; a message becomes storable and transportable independently of the speaker.

2. Romans, from c. 20 BCE — the cursus publicus, a state relay post of staged stations and mounted couriers along the imperial road network; the first organised long-distance carriage of written messages.

3. Chinese — paper in 105 CE (Cai Lun), woodblock printing by the 7th century CE and movable type c. 1040 CE (Bi Sheng); a cheap writing surface together with reproducible copies.

4. Germans, c. 1450 — Gutenberg’s movable-type press with cast metal type and the screw press; mechanised mass reproduction, the technical basis of print mass media.

5. British, from the 1830s — the Cooke–Wheatstone electric telegraph (1837) alongside the steam-driven press and mass-circulation newspapers; a message finally travels faster than any messenger.

Cross-check — The five dates are strictly increasing: c. 3400 BCE, c. 20 BCE, 105 CE, c. 1450, 1837. The chronological sequence of the developers is therefore Sumerians, Romans, Chinese, Germans, British — that is (C), (B), (D), (A), (E).

Contrast — A frequent misreading turns the item into “who invented a writing script”, which would place the Chinese oracle-bone script (c. 1200 BCE) before the Latin alphabet (c. 7th century BCE). The stem asks instead about developers of communicative systems — media together with their carriage, reproduction and transmission — and on that axis the Roman relay post precedes the Chinese paper-and-printing contribution. On either reading Sumerian cuneiform is older than both the Latin and the Chinese script, so no chain can open with the Romans or the Chinese.
