[Q]: What channel claimed that there had once been a civilization in the Amazon rainforest?, Context: The first European to travel the length of the Amazon River was Francisco de Orellana in 1542. The BBC's Unnatural Histories presents evidence that Orellana, rather than exaggerating his claims as previously thought, was correct in his observations that a complex civilization was flourishing along the Amazon in the 1540s. It is believed that the civilization was later devastated by the spread of diseases from Europe, such as smallpox. Since the 1970s, numerous geoglyphs have been discovered on deforested land dating between AD 0–1250, furthering claims about Pre-Columbian civilizations. Ondemar Dias is accredited with first discovering the geoglyphs in 1977 and Alceu Ranzi with furthering their discovery after flying over Acre. The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

[Q]: How large is the island of Guam?, Context: The island of Guam is 30 miles (50 km) long and 4 to 12 miles (6 to 19 km) wide, 3⁄4 the size of Singapore. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Sea Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active. However, due to its proximity to Anatahan, vog (i.e. volcanic smog) does occasionally affect Guam.
[A]: 3⁄4 the size of Singapore


[Q]: What were the most common immigrants in the early to mid 1700's, Context: Differences in the settlement patterns of eastern and western North Carolina, or the Low Country and uplands, affected the political, economic, and social life of the state from the 18th until the 20th century. The Tidewater in eastern North Carolina was settled chiefly by immigrants from rural England and the Scottish Highlands. The upcountry of western North Carolina was settled chiefly by Scots-Irish, English, and German Protestants, the so-called "cohee". Arriving during the mid- to late 18th century, the Scots-Irish from what is today Northern Ireland were the largest non-English immigrant group before the Revolution; English indentured servants were overwhelmingly the largest immigrant group before the Revolution. During the American Revolutionary War, the English and Highland Scots of eastern North Carolina tended to remain loyal to the British Crown, because of longstanding business and personal connections with Great Britain. The English, Welsh, Scots-Irish, and German settlers of western North Carolina tended to favor American independence from Britain.
