Input: Oklahoma
The western edge of the Oklahoma panhandle is out of alignment with its Texas border. The Oklahoma/New Mexico border is actually 2.1 to 2.2 miles east of the Texas line. The border between Texas and New Mexico was set first as a result of a survey by Spain in 1819. It was then set along the 103rd Meridian. In the 1890s, when Oklahoma was formally surveyed using more accurate surveying equipment and techniques, it was discovered that the Texas line was not set along the 103rd Meridian. Surveying techniques were not as accurate in 1819, and the actual 103rd Meridian was approximately 2.2 miles to the east. It was much easier to leave the mistake as it was than for Texas to cede land to New Mexico to correct the original surveying error. The placement of the Oklahoma/New Mexico border represents the true 103rd Meridian.

When was the border between TX and NM first determined?
Output: 1819


Input: Article: Many long-distance migrants appear to be genetically programmed to respond to changing day length. Species that move short distances, however, may not need such a timing mechanism, instead moving in response to local weather conditions. Thus mountain and moorland breeders, such as wallcreeper Tichodroma muraria and white-throated dipper Cinclus cinclus, may move only altitudinally to escape the cold higher ground. Other species such as merlin Falco columbarius and Eurasian skylark Alauda arvensis move further, to the coast or towards the south. Species like the chaffinch are much less migratory in Britain than those of continental Europe, mostly not moving more than 5 km in their lives.

Now answer this question: How far do British chaffinch more in their lives?

Output: 5 km


Article: Seattle's foreign-born population grew 40% between the 1990 and 2000 censuses. The Chinese population in the Seattle area has origins in mainland China, Hong Kong, Southeast Asia, and Taiwan. The earliest Chinese-Americans that came in the late 19th and early 20th centuries were almost entirely from Guangdong province. The Seattle area is also home to a large Vietnamese population of more than 55,000 residents, as well as over 30,000 Somali immigrants. The Seattle-Tacoma area is also home to one of the largest Cambodian communities in the United States, numbering about 19,000 Cambodian Americans, and one of the largest Samoan communities in the mainland U.S., with over 15,000 people having Samoan ancestry. Additionally, the Seattle area had the highest percentage of self-identified mixed-race people of any large metropolitan area in the United States, according to the 2000 United States Census Bureau. According to a 2012 HistoryLink study, Seattle's 98118 ZIP code (in the Columbia City neighborhood) was one of the most diverse ZIP Code Tabulation Areas in the United States.

Question: What is the population of Cambodian immigrants in Seattle?
Ans: 19,000


Here is a question about this article: The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, a line which marks the elevation at which waterfalls first appear on streams and rivers. The Piedmont region of central North Carolina is the state's most urbanized and densely populated section. It consists of gently rolling countryside frequently broken by hills or low mountain ridges. Small, isolated, and deeply eroded mountain ranges and peaks are located in the Piedmont, including the Sauratown Mountains, Pilot Mountain, the Uwharrie Mountains, Crowder's Mountain, King's Pinnacle, the Brushy Mountains, and the South Mountains. The Piedmont ranges from about 300 to 400 feet (91 to 122 m) in elevation in the east to over 1,000 feet (300 m) in the west. Because of the rapid population growth in the Piedmont, a significant part of the rural area in this region is being transformed into suburbs with shopping centers, housing, and corporate offices. Agriculture is steadily declining in importance. The major rivers of the Piedmont, such as the Yadkin and Catawba, tend to be fast-flowing, shallow, and narrow.
What is the answer to this question: What do you call the line that marks the elevation that waterfalls first appear on rivers?
****
So... Atlantic Seaboard fall line


The problem: Answer a question about this article:
A similar story is mentioned by Plutarch. He writes that the Cretan seer Epimenides purified Athens after the pollution brought by the Alcmeonidae, and that the seer's expertise in sacrifices and reform of funeral practices were of great help to Solon in his reform of the Athenian state. The story indicates that Epimenides was probably heir to the shamanic religions of Asia, and proves, together with the Homeric hymn, that Crete had a resisting religion up to historical times. It seems that these rituals were dormant in Greece, and they were reinforced when the Greeks migrated to Anatolia.
What group was probably heir to the shemanic religions of Asia?
****
The answer: Epimenides


The problem: Answer a question about this article:
Due to the patriarchal nature of Arab society, Arab men, including during the slave trade in North Africa, enslaved more black women than men. They used more black female slaves in domestic service and agriculture than males. The men interpreted the Qur'an to permit sexual relations between a male master and his female slave outside of marriage (see Ma malakat aymanukum and sex), leading to many mixed-race children. When an enslaved woman became pregnant with her Arab master's child, she was considered as umm walad or "mother of a child", a status that granted her privileged rights. The child was given rights of inheritance to the father's property, so mixed-race children could share in any wealth of the father. Because the society was patrilineal, the children took their fathers' social status at birth and were born free.
What were female slaves used for?
****
The answer:
domestic service and agriculture
