Q: To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastiao ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastiao's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755. <sep>What happened to Prince Henry?<sep>He died at the throne

Q: The little party in the cabin, so disastrously begun, finished, under the mellowing influence of wine and woman, in excellent feeling and with some hilarity. Mamie, in a plush Gainsborough hat and a gown of wine-coloured silk, sat, an apparent queen, among her rude surroundings and companions. The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil. It was the last act of the evening. Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness. But it was to Mamie that I devoted the best of my attention; and it was with her I made my chief success. <sep>Was the author usually an admirer of the women in a plush Gainsborough hat and a gown of wine-coloured silk.<sep>No one

A: No

Q: In chapters 3 and 4 we described how the U.S. government adjusted its existing agencies and capacities to address the emerging threat from Usama Bin Laden and his associates. After the August 1998 bombings of the American embassies in Kenya and Tanzania, President Bill Clinton and his chief aides explored ways of getting Bin Laden expelled from Afghanistan or possibly capturing or even killing him. Although disruption efforts around the world had achieved some successes, the core of Bin Laden's organization remained intact. President Clinton was deeply concerned about Bin Laden. He and his national security advisor, Samuel "Sandy" Berger, ensured they had a special daily pipeline of reports feeding them the latest updates on Bin Laden's reported location. In public, President Clinton spoke repeatedly about the threat of terrorism, referring to terrorist training camps but saying little about Bin Laden and nothing about al Qaeda. He explained to us that this was deliberate-intended to avoid enhancing Bin Laden's stature by giving him unnecessary publicity. His speeches focused especially on the danger of nonstate actors and of chemical and biological weapons. As the millennium approached, the most publicized worries were not about terrorism but about computer breakdowns-the Y2K scare. Some government officials were concerned that terrorists would take advantage of such breakdowns. On November 30, 1999, Jordanian intelligence intercepted a telephone call between Abu Zubaydah, a longtime ally of Bin Laden, and Khadr Abu Hoshar, a Palestinian extremist. Abu Zubaydah said, "The time for training is over." Suspecting that this was a signal for Abu Hoshar to commence a terrorist operation, Jordanian police arrested Abu Hoshar and 15 others and informed Washington. One of the 16, Raed Hijazi, had been born in California to Palestinian parents; after spending his childhood in the Middle East, he had returned to northern California, taken refuge in extremist Islamist beliefs, and then made his way to Abu Zubaydah's Khaldan camp in Afghanistan, where he learned the fundamentals of guerrilla warfare. He and his younger brother had been recruited by Abu Hoshar into a loosely knit plot to attack Jewish and American targets in Jordan. After late 1996, when Abu Hoshar was arrested and jailed, Hijazi moved back to the United States, worked as a cabdriver in Boston, and sent money back to his fellow plotters. After Abu Hoshar's release, Hijazi shuttled between Boston and Jordan gathering money and supplies. With Abu Hoshar, he recruited inTurkey and Syria as well as Jordan; with Abu Zubaydah's assistance, Abu Hoshar sent these recruits to Afghanistan for training. <sep>Who was considered a threat to the U.S Government?<sep>Government
