Q0180Q0181The last woolly mammoths were still alive when the pyramids were being built in Egypt.
Small mammoth populations survived on Wrangel Island until about 1650 BC — meaning the last mammoths lived while Egypt's pyramids already stood.
Q0182Oxford University was teaching students before the Aztec Empire existed.
Teaching at Oxford is documented from 1096, and it grew rapidly after 1167. The Aztec capital Tenochtitlan was not founded until 1325 — over two centuries later.
Q0183The Roman Empire still existed in the East for almost 1,000 years after Rome itself fell.
Rome fell in the West in 476 AD, but the Eastern Roman (Byzantine) Empire endured until 1453 — nearly a thousand more years of Roman law, faith and rule.
Q0187The oldest known peace treaty was signed between Egypt and the Hittites after the Battle of Kadesh.
The Egyptian–Hittite treaty of about 1259 BC, after the Battle of Kadesh, is the oldest surviving peace treaty whose full text we can still read.
Q0189Pompeii was buried so quickly by Mount Vesuvius that it preserved daily Roman life in extraordinary detail.
When Mount Vesuvius erupted in AD 79, ash and pumice buried Pompeii within about a day, and searing pyroclastic surges killed those who had stayed. The burial was so fast and so complete that it sealed a Roman town mid-life: loaves still in ovens, election slogans on walls, wine jars in taverns. We even have an eyewitness — Pliny the Younger, who watched from across the bay and described the column of ash in two letters to the historian Tacitus. Rediscovered in the 1740s, Pompeii became the single richest window archaeology has onto everyday Roman life.
Q0190Ancient Roman concrete was so durable that some harbour structures still survive after 2,000 years.
Roman harbour concrete used volcanic ash and lime that kept reacting with seawater, growing new minerals in cracks. Some structures still stand after 2,000 years.
Q0191The Olympic Games were already more than 1,000 years old when they were banned in the Roman Empire.
The ancient Olympic Games ran from 776 BC and were held for over a millennium before a Roman emperor banned them around AD 393 as a pagan festival.
Q0192The Silk Road was not one road, but a network of trade routes connecting cultures across Asia, Africa, and Europe.
The Silk Road was a web of overland and sea routes. Along it moved not just silk but paper-making, faiths, numerals — and, at times, disease.
Q0194Genghis Khan's empire connected East and West so widely that goods, people, disease, and ideas moved faster than ever before.
By linking East and West under one rule, the Mongols let goods, people and ideas flow along protected roads — and plague travelled the same routes.
Q0195The Black Death killed such a large part of Europe's population that it helped change labour, wages, and social power.
The Black Death killed so many workers that survivors could demand better pay and conditions — helping loosen the rigid ties of feudal society.
Q0196The Renaissance was not just a rebirth of art. It was also a revolution in how humans saw themselves.
The Renaissance revived classical art, but also changed how people saw the world — reviving inquiry, perspective and a new confidence in human reason.
Q0197Leonardo da Vinci left thousands of pages of notes, but many of his inventions were never built in his lifetime.
Leonardo filled thousands of notebook pages with flying machines, gears and studies — but many designs were never built, hidden for centuries in his mirror-writing.
Q0199The fall of Constantinople in 1453 helped push Greek scholars and ancient texts westward into Renaissance Europe.
When Constantinople fell in 1453, Greek scholars fled west carrying ancient manuscripts — fuel that helped feed the Italian Renaissance.
Q0200Coffeehouses became centres of politics, business, science, and gossip in early modern Europe and the Middle East.
17th- and 18th-century coffeehouses were called 'penny universities': for the price of a coffee, anyone could join debates on politics, trade and science.
Q0201The word 'salary' is linked to salt, because salt was once valuable enough to shape trade and payment.
'Salary' comes from the Latin salarium, rooted in sal, salt. Salt was once so valuable it shaped trade routes and, some say, part of a soldier's pay.
Q0202The Industrial Revolution changed human life so deeply that work, cities, time, and family routines were reorganised around machines.
The Industrial Revolution reshaped daily life at the root — moving people to cities, ruling the day by the clock, and remaking work and the family.
Q0204Humans went from the first powered flight to landing on the Moon in less than 70 years.
From Kitty Hawk in 1903 to the Moon in 1969 was just 66 years — a single long lifetime spanning the whole leap from first flight to lunar landing.
Q0205The United Nations was created after World War II to prevent another global catastrophe.
Founded in 1945 after the Second World War, the United Nations was built to give nations a table to talk at, hoping to prevent another global catastrophe.
Q0206The Cold War was fought not only with weapons, but with science, sport, propaganda, cinema, and space exploration.
The rivalry shaped more than military strategy: classrooms, films, Olympic arenas, laboratories and the space race all became stages for influence.
Q0207The Space Race turned the sky into a political battlefield — and accidentally built the world we live in.
It began in October 1957, when Sputnik — a beeping metal sphere just 58 cm wide — passed over America and triggered the creation of NASA within a year. Twelve years later, Apollo 11 stood on the Moon. But the race's real legacy is under your thumb: weather and communication satellites, GPS navigation, and a young microchip industry supercharged by Apollo's demand for tiny, reliable electronics. The rivalry was political; the infrastructure it left behind became everyone's.
Q0208The first human in space was Yuri Gagarin in 1961.
On 12 April 1961 Yuri Gagarin orbited Earth once aboard Vostok 1, becoming the first human in space — a flight of about 108 minutes.
Q0209The first words spoken from the Moon were heard on Earth almost instantly, but the signal travelled across nearly 400,000 kilometres (250,000 miles).
Radio signals travel at light speed, so the Moon's words reached Earth in about 1.3 seconds — near-instant, yet still a measurable delay across 384,000 km (239,000 miles).
Q0210The Berlin Wall stood for 28 years and fell in 1989.
The Berlin Wall divided the city from 1961 until 1989, when it was opened almost overnight — a sudden end to a 28-year symbol of a divided world.
