Input: Read this: Located in the South Atlantic Ocean on the Mid-Atlantic Ridge, more than 2,000 kilometres (1,200 mi) from the nearest major landmass, Saint Helena is one of the most remote places in the world. The nearest port on the continent is Namibe in southern Angola, and the nearest international airport the Quatro de Fevereiro Airport of Angola's capital Luanda; connections to Cape Town in South Africa are used for most shipping needs, such as the mail boat that serves the island, the RMS St Helena. The island is associated with two other isolated islands in the southern Atlantic, also British territories: Ascension Island about 1,300 kilometres (810 mi) due northwest in more equatorial waters and Tristan da Cunha, which is well outside the tropics 2,430 kilometres (1,510 mi) to the south. The island is situated in the Western Hemisphere and has the same longitude as Cornwall in the United Kingdom. Despite its remote location, it is classified as being in West Africa by the United Nations.

Output: the Quatro de Fevereiro Airport

Input: Read this: Combined with this influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would later lead to the Protestant Reformation. Toward the end of the period, an era of discovery began (Age of Discovery). The rise of the Ottoman Empire, culminating in the Fall of Constantinople in 1453, eroded the last remnants of the Byzantine Empire and cut off trading possibilities with the east. Europeans were forced to seek new trading routes, leading to the expedition of Columbus to the Americas in 1492, and Vasco da Gama's circumnavigation of India and Africa in 1498. Their discoveries strengthened the economy and power of European nations.
Question: In what year did Vasco da Gama sail through India and Africa?

Output: unanswerable

Input: Read this: Anti-miscegenation laws were passed in most states during the 18th, 19th and early 20th centuries, but this did not prevent white slaveholders, their sons, or other powerful white men from taking slave women as concubines and having multiracial children with them. In California and the western US, there were greater numbers of Latino and Asian residents. These were prohibited from official relationships with whites. White legislators passed laws prohibiting marriage between European and Asian Americans until the 1950s.
Question: Why did the anti-miscegenation not insure that there was no interracial mixing?

Output:
white men from taking slave women as concubines and having multiracial children with them
