Problem: The southeast corner of Siberia south of the Stanovoy Range was twice contested between Russia and China. Hydrologically, the Stanovoy Range separate the rivers that flow north into the Arctic from those that flow south into the Amur River.  Ecologically, the area is the southeastern edge of the Siberian boreal forest with some areas good for agriculture. Socially and politically, from about 600 AD, it was the northern fringe of the Chinese-Manchu world. Various Chinese dynasties would claim sovereignty, build forts and collect tribute when they were strong enough.  The Ming dynasty Nurgan Regional Military Commission built a fort on the Northern bank of the Amur at Aigun, and established an administrative seat at Telin, modern Tyr, Russia above Nikolaevsk-on-Amur. Russian expansion into Siberia began with the conquest of the Khanate of Sibir in 1582.  By 1643 they reached the Pacific at Okhotsk. East of the Yenisei River there was little land fit for agriculture, except Dauria, the land between the Stanovoy Range and the Amur River which was nominally subject to the Qing dynasty. In 1643, Russian adventurers spilled over the Stanovoy Range, but by 1689 they were driven back by the Qing. The land was populated by some 9,000 Daurs on the Zeya River, 14,000 Duchers downstream and several thousand Tungus and Nivkhs toward the river mouth. The first Russians to hear of Dauria were probably Ivan Moskvitin and Maxim Perfilev about 1640. In 1859/60 the area was annexed by Russia and quickly filled up with a Russian population.

The median age was 39 years. For every 100 females there were 97.10 males.  For every 100 females age 18 and over, there were 93.60 males.
Answer this question based on the article: Which age group is larger: 25 to 44 or 45 to 64?
A: 25 to 44

Problem: Nova Scotia's governor launched a campaign to end the Mi'kmaq blockade of Annapolis Royal at the end of July 1722. They retrieved over 86 New England prisoners taken by the Indians. One of these operations resulted in the Battle at Winnepang , in which 35 Indians and five New Englanders were killed. Only five Indian bodies were recovered from the battle, and the New Englanders decapitated the corpses and set the severed heads on pikes surrounding Canso's new fort. During the war, a church was erected at the Catholic mission in the Mi'kmaq village of Shubenacadie . In 1723, the village of Canso, Nova Scotia was raided again by the Mi'kmaqs, who killed five fishermen, so the New Englanders built a 12-gun blockhouse to guard the village and fishery.:62 The worst moment of the war for Annapolis Royal came on July 4, 1724 when a group of 60 Mi'kmaqs and Maliseets raided the capital. They killed and scalped a sergeant and a private, wounded four more soldiers, and terrorized the village. They also burned houses and took prisoners.:164-165 The New Englanders responded by executing one of the Mi'kmaq hostages on the same spot where the sergeant was killed. They also burned three Acadian houses in retaliation. As a result of the raid, three blockhouses were built to protect the town. The Acadian church was moved closer to the fort so that it could be more easily monitored. In 1725, 60 Abenakis and Mi'kmaqs launched another attack on Canso, destroying two houses and killing six people.
