Problem: Human settlement of the New World occurred in stages from the Bering sea coast line, with an initial 15,000 to 20,000-year layover on Beringia for the small founding population. The micro-satellite diversity and distributions of the Y lineage specific to South America indicates that certain indigenous peoples of the Americas populations have been isolated since the initial colonization of the region. The Na-Dene, Inuit and Indigenous Alaskan populations exhibit haplogroup Q (Y-DNA) mutations, however are distinct from other indigenous peoples of the Americas with various mtDNA and atDNA mutations. This suggests that the earliest migrants into the northern extremes of North America and Greenland derived from later migrant populations.
What do the diversity and distributions of Y lineage specific to South America indicate about certain peoples there?

Answer: isolated since the initial colonization of the region

Problem: The Western powers, largely unsatisfied with the Treaty of Nanjing, gave grudging support to the Qing government during the Taiping and Nian Rebellions. China's income fell sharply during the wars as vast areas of farmland were destroyed, millions of lives were lost, and countless armies were raised and equipped to fight the rebels. In 1854, Britain tried to re-negotiate the Treaty of Nanjing, inserting clauses allowing British commercial access to Chinese rivers and the creation of a permanent British embassy at Beijing.
Who did the Europeans support during the Rebellions?

Answer: Qing government

Problem: In 1974 ministerial government was introduced to the Gilbert and Ellice Islands Colony through a change to the Constitution. In that year a general election was held; and a referendum was held in December 1974 to determine whether the Gilbert Islands and Ellice Islands should each have their own administration. As a consequence of the referendum, separation occurred in two stages. The Tuvaluan Order 1975, which took effect on 1 October 1975, recognised Tuvalu as a separate British dependency with its own government. The second stage occurred on 1 January 1976 when separate administrations were created out of the civil service of the Gilbert and Ellice Islands Colony.
What document was changed to cause a change in government?
---
Answer:
Constitution
