Beyond the answers - interesting background to this quiz

The Mountain With Two Names

Denali, the highest peak in North America, was officially known as Mount McKinley for much of the 20th century. The name Denali comes from the Koyukon Athabaskan language and means "the high one" or "the great one". In 2015, the United States officially restored the indigenous name, reflecting a broader effort to recognise the cultural heritage tied to Alaska's most famous summit.

A Small Country Inside a City

Vatican City is not only the smallest sovereign state by population, but also by area. Entirely surrounded by Rome, it functions as the spiritual and administrative centre of the Roman Catholic Church. Its population fluctuates because most residents are clergy, Swiss Guards or officials serving the Holy See, and citizenship is typically granted only for the duration of one's service.

The trilogy has since become one of the best-selling books ever written.

Challenger was the second orbiter in NASA's Space Shuttle fleet, first flying in 1983. Its name was chosen partly to honour HMS Challenger, a British naval vessel that conducted a major scientific expedition in the 1870s. The shuttle completed nine successful missions before the tragic accident in January 1986, which profoundly changed the American space programme.
