World Facts and Geography

Germany developed the first operational jet engine, the Heinkel HeS 3, which powered the Heinkel He 178's maiden flight in 1939. Hans von Ohain and Ernst Heinkel led this breakthrough. While Britain (Frank Whittle) independently developed jet technology around the same time, Germany's was the first to actually fly.

Australia is the only continent without current glaciers. While Australia has glacial landforms from past ice ages, it has no active glaciers today. All other continents including Antarctica, North America, Europe, Asia, South America, and Africa have glaciers. Africa has glaciers on Mount Kilimanjaro and Mount Kenya, though they are rapidly receding.

Zimbabwe was formerly known as Rhodesia, named after Cecil John Rhodes. The country gained independence in 1980 and changed its name to Zimbabwe. Persia is the old name for Iran, not Zimbabwe. South-West Africa was the old name for Namibia, not Zimbabwe.

Namibia was formerly known as South-West Africa during the colonial period and under South African administration. It gained independence in 1990. Ethiopia and Zambia are different African countries, and South-East Africa is not the old name for any specific country.

Ghana was formerly known as the Gold Coast due to its abundant gold resources. The name was changed to Ghana upon independence in 1957, inspired by the ancient West African Ghana Empire. The other options (Silver, Diamond, Bronze Coast) are fictional names.

Ethiopia was historically known as Abyssinia for centuries, derived from the Arabic 'Al-Habash.' This name was used in European maps and documents until the mid-20th century. Rhodesia is modern-day Zimbabwe, and Malaysia is in Southeast Asia.

Botswana was called Bechuanaland during British colonial rule. The name means 'land of the Tswana people' and was changed to Botswana (meaning the same) upon independence in 1966. The spelling variants with 'Ch' are incorrect.

Kampuchea is the Khmer name for Cambodia, used officially during different periods especially the 1970s-1980s. Option B 'Combodia' is a typo for Cambodia - Kampuchea IS Cambodia. The question asks for the old name, but presents the current name as the answer. This tests recognition that Kampuchea equals Cambodia.

Iran was officially known as Persia until 1935, when Reza Shah requested that the international community use the name Iran, which is what Iranians had always called their country. The name Persia comes from the ancient region of Pars (Fars province).

Sri Lanka's national flag features a lion holding a sword, which is the central emblem of the flag. The lion has been a symbol of Sri Lanka (formerly Ceylon) for centuries. Bangladesh's flag has a red circle, China's flag has five stars, and Nepal's flag has a unique double-pennon shape with celestial symbols.

The Netherlands has a national dog breed called the Keeshond (also known as the Dutch Barge Dog). It was the symbol of the Dutch Patriot political party in the 18th century. No other country has an officially designated 'national dog,' though many have national breeds.

In Russia, people traditionally answer the phone by saying 'Ya slushayu' (Я слушаю), which literally translates to 'I'm listening' - a distinctive cultural phone greeting.

Plaza México in Mexico City is the world's largest bullfighting ring, seating over 41,000 spectators - bullfighting is traditionally associated with Spanish and Latin American cultures.

Alaska has the most outhouses of any US state due to its vast remote areas and challenging terrain that make traditional sewage systems impractical - many rural residents still rely on outhouses today.
