Article: U.S. submarines, as well as some British and Dutch vessels, operating from bases at Cavite in the Philippines (1941–42); Fremantle and Brisbane, Australia; Pearl Harbor; Trincomalee, Ceylon; Midway; and later Guam, played a major role in defeating Japan, even though submarines made up a small proportion of the Allied navies—less than two percent in the case of the US Navy. Submarines strangled Japan by sinking its merchant fleet, intercepting many troop transports, and cutting off nearly all the oil imports essential to weapons production and military operations. By early 1945 Japanese oil supplies were so limited that its fleet was virtually stranded.

Question: What percent did submarines make up in the US Navy fighting Japan?
Ans: two percent


Article: International pressure led to a ceasefire, and by then 37% of the island had been taken over by the Turks and 180,000 Greek Cypriots had been evicted from their homes in the north. At the same time, around 50,000 Turkish Cypriots moved to the areas under the control of the Turkish Forces and settled in the properties of the displaced Greek Cypriots. Among a variety of sanctions against Turkey, in mid-1975 the US Congress imposed an arms embargo on Turkey for using American-supplied equipment during the Turkish invasion of Cyprus in 1974. There are 1,534 Greek Cypriots and 502 Turkish Cypriots missing as a result of the fighting.

Question: In what year did the US impose an arms embargo on Turkey?
Ans: 1975


Article: When the Dzungar Mongols attempted to spread their territory from what is now Xinjiang into Tibet, the Kangxi Emperor (r. 1661–1722) responded to Tibetan pleas for aid with his own expedition to Tibet, occupying Lhasa in 1720. By 1751, during the reign of the Qianlong Emperor (r. 1735–1796), a protectorate and permanent Qing dynasty garrison was established in Tibet. As of 1751, Albert Kolb writes that "Chinese claims to suzerainty over Tibet date from this time."

Question: When did the Qianlong Emperor reign? 
Ans: 1735–1796


Article: In contrast to the entirely digital DVD, LaserDiscs use only analog video. As the LaserDisc format is not digitally encoded and does not make use of compression techniques, it is immune to video macroblocking (most visible as blockiness during high motion sequences) or contrast banding (subtle visible lines in gradient areas, such as out-of-focus backgrounds, skies, or light casts from spotlights) that can be caused by the MPEG-2 encoding process as video is prepared for DVD. Early DVD releases held the potential to surpass their LaserDisc counterparts, but often managed only to match them for image quality, and in some cases, the LaserDisc version was preferred. However, proprietary human-assisted encoders manually operated by specialists can vastly reduce the incidence of artifacts, depending on playing time and image complexity. By the end of LaserDisc's run, DVDs were living up to their potential as a superior format.

Question: Are DVDs partially or entirely digital?
Ans:
entirely
