Today’s first question concerns the date May 26th. The subsequent questions share a theme established in the first one.
One
On 26 May 1876, HMS Challenger returned to Great Britain from a three-and-a-half-year, groundbreaking oceanographic expedition which circumnavigated the Earth. How many miles or kilometres, to the nearest 1,000, did the ship sail on its voyage?
Answer: 79,000 miles or 128,000 kilometres.
The Challenger expedition (1872–1876), led by Captain George Nares and supervised by Sir Charles Wyville Thomson, was a groundbreaking scientific programme that established oceanography. HMS Challenger, a joint effort by the British Admiralty and the Royal Society, travelled 68,890 nautical miles (79,278 miles or 127,584 kilometres), cataloguing over 4,000 unknown species, collecting ocean floor samples, measuring depths, and recording currents. It was the first to photograph icebergs and approached Antarctica, significantly advancing planetary knowledge.

These three points all relate to the same person, there are three answers.
- What is the name of the explorer and navigator after whom the Americas are named?
- In what modern country is his birthplace?
- What two countries sponsored his voyages?
Answers.
- Amerigo Vespucci
- Italy
- Spain and Portugal
America is named after Amerigo Vespucci (1454–1512), an Italian explorer from the Republic of Florence. He participated in voyages for Spain (1499–1500) and Portugal (1501–1502) during the Age of Discovery. Two booklets published under his name in 1503 and 1505 described these explorations, although their authorship is disputed. Vespucci argued that Brazil was part of a previously unknown continent—the ‘New World’—which inspired the German cartographer Martin Waldseemüller to use the name ‘America’, the Latinised feminine form of Amerigo, on his 1507 world map.
Three
These three points all relate to the same person, there is only one answer.
- Edgar Allan Poe dedicated his final major work Eureka: A Prose Poem to this scientist and explorer
- The same explorer authored the five-volume treatise Kosmos (1845-62)
- Charles Darwin read and referenced Helen Maria Williams’s English translation of this explorer’s Relation historique du voyage aux régions équinoxiales du nouveau continent during his voyage on the HMS Beagle.
Which explorer do the above all refer to?
Answer: Alexander von Humboldt.
Alexander von Humboldt (1769–1859) was a German naturalist and explorer renowned for advancing geography, biogeography, and Earth sciences. Initially a restless student, he became passionate about botany, mineralogy, and geology, later joining the Prussian Mining Department. Driven by scientific ambition, he financed and undertook a five-year expedition (1799–1804) across Central and South America with Aimé Bonpland, studying flora, fauna, rivers, mountains, and the Humboldt Current. His discoveries, measurements, and writings, notably Kosmos, profoundly popularised science worldwide.

How many years did Marco Polo spend travelling across Asia?
Answer: 24 years.
Marco Polo was a Venetian merchant and adventurer who travelled across Asia from 1271 to 1295, spending 17 years in China under the rule of Kublai Khan. Accompanying his father and uncle along the Silk Road, he journeyed through Persia, Central Asia, and the Gobi Desert before reaching the Mongol court. His experiences were recorded in Il milione(The Travels of Marco Polo), one of history’s most influential travel books, introducing Europeans to the cultures, cities, and wealth of Asia.
Five
In what century did a Greek explorer first visit the British Isles?
Answer: 4th century BCE.
Pytheas was a Greek navigator, geographer, and astronomer from Massalia (Marseille) who explored northern Europe around 325 BC. Sailing beyond the Mediterranean into the Atlantic, he visited Spain, Brittany, Cornwall, and much of Britain, accurately estimating distances and Britain’s circumference. Although his book On the Ocean is lost, later writers preserved his observations on tides, polar ice, the midnight sun, and northern peoples. His voyages greatly expanded Greek knowledge of Europe and the far north.
