IELTS Reading 8: True/False/Not Given — Full Passage Practice (Mixed Review)

"In the second half of the nineteenth century, many large cities faced a communication problem: telegraph offices could transmit messages across continents in minutes, but delivering those messages the final few kilometres through crowded streets could take hours. The solution, first installed in London in 1853, was the pneumatic post — a network of underground tubes through which capsules containing letters and telegrams were propelled by compressed air.

Paris built the most extensive system of all. At its peak, the Parisian network stretched for more than 400 kilometres beneath the city, and a message posted at one end of the capital could reach the other in under two hours — far faster than a courier on the congested streets above. The service proved enormously popular with the public, who used special lightweight forms known as 'petits bleus' for their messages.

The pneumatic post declined for a simple reason: the telephone made it unnecessary for most everyday communication. Berlin closed its network in 1976, and Paris followed in 1984. Yet the technology has not disappeared entirely — many hospitals today still use pneumatic tubes to move blood samples and medicines between departments, where speed and reliability matter more than cost."
