PROBLEM: Passage: AA gunnery was a difficult business. The problem was of successfully aiming a shell to burst close to its target's future position, with various factors affecting the shells' predicted trajectory. This was called deflection gun-laying, 'off-set' angles for range and elevation were set on the gunsight and updated as their target moved. In this method when the sights were on the target, the barrel was pointed at the target's future position. Range and height of the target determined fuse length. The difficulties increased as aircraft performance improved. Question: What was the problem with AA gunnery?

SOLUTION: successfully aiming a shell to burst close to its target's future position

PROBLEM: Passage: During the 1800s Christian missionaries from Great Britain and the United States followed traders to the Hawaiian islands. Long-termly, the Anglo-Saxon presence negatively impacted the level of regard Hawaiian royal women held for their own indigenous looks. For centuries prior the arrival of Christians, first nation Hawaiian aesthetics, such as dark skin and ample bodies, had been considered signs of nobility. No matter how much they adapted their mannerisms to Western standard, some of the Anglo-Saxon missionaries were relentless in referring to the indigenous women as "Hawaiian squaws." By the last half of the 19th century, some Hawaiian women began marrying European men who found them exotic. The men, however, selected Hawaiian women who were thinner and paler in complexion. Question: When would white men marry the paler and thinner Hawaiian ladies?

SOLUTION: By the last half of the 19th century

PROBLEM: Passage: Dvaita Vedanta is a dualistic interpretation of the Vedas, espouses dualism by theorizing the existence of two separate realities. The first and the only independent reality, states the Dvaita school, is that of Vishnu or Brahman. Vishnu is the supreme Self, in a manner similar to monotheistic God in other major religions. The distinguishing factor of Dvaita philosophy, as opposed to monistic Advaita Vedanta, is that God takes on a personal role and is seen as a real eternal entity that governs and controls the universe. Like Vishishtadvaita Vedanta subschool, Dvaita philosophy also embraced Vaishnavism, with the metaphysical concept of Brahman in the Vedas identified with Vishnu and the one and only Supreme Being. However, unlike Vishishtadvaita which envisions ultimate qualified nondualism, the dualism of Dvaita was permanent. Question: As what did the Dvaita school view dualism?

SOLUTION:
permanent
