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.

Problem: In 1990, the U.S. Custom House in New York City was renamed after Hamilton. In 1880, his son John Church Hamilton commissioned Carl Conrads to sculpt a granite statue, now located in Central Park, New York City. One statue honoring Alexander Hamilton in Chicago was mired in controversy, at least concerning the surrounding architecture. Kate Sturges Buckingham (1858-1937), of the Buckingham Fountain family, commissioned the monument. Its impetus was that Treasury Secretary Hamilton "secured the nation's financial future and made it possible for her own family to make its fortune in grain elevators and banking. Consequently, John Angel was hired to model a figurative sculpture and the Finnish architect Eliel Saarinen was to create a "colossal architectural setting" for it. The proposed 80-foot tall columned shelter was poorly received. By Ms. Buckingham's death in 1937, the sculpture's setting. location and design were uncertain. Conspiracy allegations surfaced, and the matter became mired in litigation. After the courts ordered the construction to be completed by 1953, the trustees hired architect Samuel A. Marx. The structure was completed, had structural problems, and was eventually demolished in 1993. The statue was gilded, and is still on display. A statue, by James Earle Fraser, was dedicated on May 17, 1923, on the south terrace of the Treasury Building, in Washington.

Question: "For how many years did Ms. Buckinghams statue of Alexander Hamilton stand?"

Answer: "It stood for 40 years"

Input: Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation.

Does the response "Abdul Aziz al Omari" correctly answer the question "Who boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport with Mohamad Atta and arrived at Boston at 6:45 pm?"?
