[EX 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>Who became sick and died heirless?<sep>Prince Henry became sick
[EX A]: Yes

[EX Q]: After the disruption of the plot in Amman, it had not escaped notice in Washington that Hijazi had lived in California and driven a cab in Boston and that Deek was a naturalized U.S. citizen who, as Berger reminded President Clinton, had been in touch with extremists in the United States as well as abroad. Before Ressam's arrest, Berger saw no need to raise a public alarm at home- although the FBI put all field offices on alert. Now, following Ressam's arrest, the FBI asked for an unprecedented number of special wiretaps. Both Berger andTenet told us that their impression was that more Foreign Intelligence Surveillance Act (FISA) wiretap requests were processed during the millennium alert than ever before. The next day, writing about Ressam's arrest and links to a cell in Montreal, Berger informed the President that the FBI would advise police in the United States to step up activities but would still try to avoid undue public alarm by stressing that the government had no specific information about planned attacks. At a December 22 meeting of the Small Group of principals, FBI Director Louis Freeh briefed officials from the NSC staff, CIA, and Justice on wiretaps and investigations inside the United States, including a Brooklyn entity tied to the Ressam arrest, a seemingly unreliable foreign report of possible attacks on seven U.S. cities, two Algerians detained on the Canadian border, and searches in Montreal related to a jihadist cell. The Justice Department released a statement on the alert the same day. Clarke's staff warned, "Foreign terrorist sleeper cells are present in the US and attacks in the US are likely." Clarke asked Berger to try to make sure that the domestic agencies remained alert." Is there a threat to civilian aircraft?"he wrote. Clarke also asked the principals in late December to discuss a foreign security service report about a Bin Laden plan to put bombs on transatlantic flights. The CSG met daily. Berger said that the principals met constantly. Later, when asked what made her decide to ask Ressam to step out of his vehicle, Diana Dean, a Customs inspector who referred Ressam to secondary inspection, testified that it was her "training and experience." It appears that the heightened sense of alert at the national level played no role in Ressam's detention. There was a mounting sense of public alarm. The earlier Jordanian arrests had been covered in the press, and Ressam's arrest was featured on network evening news broadcasts throughout the Christmas season. The FBI was more communicative during the millennium crisis than it had ever been. <sep>On what date did the warning "Foreign terrorist sleeper cells are present in the US and attacks in the US are likely." take place?<sep>Christmas day
[EX A]: No
