Article: Most of the English colonists had arrived as indentured servants, hiring themselves out as laborers for a fixed period to pay for their passage. In the early years the line between indentured servants and African slaves or laborers was fluid. Some Africans were allowed to earn their freedom before slavery became a lifelong status. Most of the free colored families formed in North Carolina before the Revolution were descended from unions or marriages between free white women and enslaved or free African or African-American men. Because the mothers were free, their children were born free. Many had migrated or were descendants of migrants from colonial Virginia. As the flow of indentured laborers to the colony decreased with improving economic conditions in Great Britain, planters imported more slaves, and the state's legal delineations between free and slave status tightened, effectively hardening the latter into a racial caste. The economy's growth and prosperity was based on slave labor, devoted first to the production of tobacco.

Question: Indentured servants were similar to what people in the early days?
Ans: African slaves


Article: The First Opium War revealed the outdated state of the Chinese military. The Qing navy, composed entirely of wooden sailing junks, was severely outclassed by the modern tactics and firepower of the British Royal Navy. British soldiers, using advanced muskets and artillery, easily outmaneuvered and outgunned Qing forces in ground battles. The Qing surrender in 1842 marked a decisive, humiliating blow to China. The Treaty of Nanjing, the first of the unequal treaties, demanded war reparations, forced China to open up the five ports of Canton, Amoy, Fuchow, Ningpo and Shanghai to western trade and missionaries, and to cede Hong Kong Island to Britain. It revealed many inadequacies in the Qing government and provoked widespread rebellions against the already hugely unpopular regime.

Question: What treaty marked the end of the First Opium War?
Ans: Treaty of Nanjing,


Article: By 1640, the town's theocratic government and nine-square grid plan were in place, and the town was renamed Newhaven from Quinnipiac. However, the area north of New Haven remained Quinnipiac until 1678, when it was renamed Hamden. The settlement became the headquarters of the New Haven Colony. At the time, the New Haven Colony was separate from the Connecticut Colony, which had been established to the north centering on Hartford. One of the principal differences between the two colonies was that the New Haven colony was an intolerant theocracy that did not permit other churches to be established, while the Connecticut colony permitted the establishment of other churches.

Question: What was the name of the area north of New Haven changed to in 1678?
Ans: Hamden


Article: A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain in some conditions, though the number of patients enrolled in the studies was low, bringing up issues of power to detect group differences, and most lacked credible controls for placebo and/or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."

Question: Clinical hypnosis may be effective in doing what with pain associated with surgical procedures in adults and children?
Ans:
controlling
