QUES: Extending the Gregorian calendar backwards to dates preceding its official introduction produces a proleptic calendar, which should be used with some caution. For ordinary purposes, the dates of events occurring prior to 15 October 1582 are generally shown as they appeared in the Julian calendar, with the year starting on 1 January, and no conversion to their Gregorian equivalents. For example, the Battle of Agincourt is universally considered to have been fought on 25 October 1415 which is Saint Crispin's Day.
What is the disputed date for St. Crispin's Day?

ANS: unanswerable

QUES: The U.S. framed the war as part of its policy of containment of Communism in south Asia, but American forces were frustrated by an inability to engage the enemy in decisive battles, corruption and incompetence in the Army of the Republic of Vietnam, and ever increasing protests at home. The Tet Offensive in 1968, although a major military defeat for the NLF with half their forces eliminated, marked the psychological turning point in the war. With President Richard M. Nixon opposed to containment and more interested in achieving detente with both the Soviet Union and China, American policy shifted to "Vietnamization," providing very large supplies of arms and letting the Vietnamese fight it out themselves. After more than 57,000 dead and many more wounded, American forces withdrew in 1973 with no clear victory, and in 1975 South Vietnam was finally conquered by communist North Vietnam and unified.
What was the psychological turning point of the war?

ANS: The Tet Offensive

QUES: New York City is supplied with drinking water by the protected Catskill Mountains watershed. As a result of the watershed's integrity and undisturbed natural water filtration system, New York is one of only four major cities in the United States the majority of whose drinking water is pure enough not to require purification by water treatment plants. The Croton Watershed north of the city is undergoing construction of a US$3.2 billion water purification plant to augment New York City's water supply by an estimated 290 million gallons daily, representing a greater than 20% addition to the city's current availability of water. The ongoing expansion of New York City Water Tunnel No. 3, an integral part of the New York City water supply system, is the largest capital construction project in the city's history.
How much is being spent on a water purification plant at the Croton Watershed?

ANS: US$3.2 billion

QUES: Further claims were made that the Roman Catholic Church derives its doctrine from the Islamic teaching. In volume 5 of his Decline and Fall of the Roman Empire, published in 1788, Edward Gibbon wrote: "The Latin Church has not disdained to borrow from the Koran the immaculate conception of his virgin mother." That he was speaking of her immaculate conception by her mother, not of her own virginal conception of Jesus, is shown by his footnote: "In the xiith century the immaculate conception was condemned by St. Bernard as a presumptuous novelty." In the aftermath of the definition of the dogma in 1854, this charge was repeated: "Strange as it may appear, that the doctrine which the church of Rome has promulgated, with so much pomp and ceremony, 'for the destruction of all heresies, and the confirmation of the faith of her adherents', should have its origin in the Mohametan Bible; yet the testimony of such authorities as Gibbon, and Sale, and Forster, and Gagnier, and Maracci, leave no doubt as to the marvellous fact."
