An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals. Larger airports may have fixed base operator services, airport aprons, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services.

Input: Read this: Popper left school at the age of 16 and attended lectures in mathematics, physics, philosophy, psychology and the history of music as a guest student at the University of Vienna. In 1919, Popper became attracted by Marxism and subsequently joined the Association of Socialist School Students. He also became a member of the Social Democratic Workers' Party of Austria, which was at that time a party that fully adopted the Marxist ideology. After the street battle in the Horlgasse on 15 June 1919, when police shot eight of his unarmed party comrades, he became disillusioned by what he saw to be the "pseudo-scientific" historical materialism of Marx, abandoned the ideology, and remained a supporter of social liberalism throughout his life.
Question: What age did Popper enter school?

Output: unanswerable

Input: Read this: The native language of the Romans was Latin. Although surviving Latin literature consists almost entirely of Classical Latin, an artificial and highly stylised and polished literary language from the 1st century BC, the actual spoken language was Vulgar Latin, which significantly differed from Classical Latin in grammar, vocabulary, and eventually pronunciation. Rome's expansion spread Latin throughout Europe, and over time Vulgar Latin evolved and dialectised in different locations, gradually shifting into a number of distinct Romance languages. Many of these languages, including French, Italian, Portuguese, Romanian and Spanish, flourished, the differences between them growing greater over time. Although English is Germanic rather than Roman in origin, English borrows heavily from Latin and Latin-derived words.[citation needed]
Question: How would Vulgar Latin eventually differ from Classical Latin?

Output: pronunciation

Input: Read this: According to the prevailing theories of the settlement of the Americas, migrations of humans from Asia (in particular North Asia) to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The majority of experts agree that the earliest pre-modern human migration via Beringia took place at least 13,500 years ago, with disputed evidence that people had migrated into the Americas much earlier, up to 40,000 years ago. These early Paleo-Indians spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of creation myths.
Question: Most experts can at least agree that the earliest pre-modern human migration took place when?

Output:
13,500 years ago
