Input: In the popular mind, the history of Hong Kong, long the entryway to China for Westerners, begins in 1841 with the British occupation of the territory. However, it would be wrong to dismiss the long history of the region itself. Archaeologists today are working to uncover Hong Kong's past, which stretches back thousands of years. You can get a glimpse into that past at Lei Cheng Uk Museum's 1,600-year-old burial vault on the mainland just north of Kowloon. In 1992, when construction of the airport on Chek Lap Kok was begun, a 2,000-year-old village, Pak Mong, was discovered, complete with artifacts that indicated a sophisticated rural society. An even older Stone Age site was discovered on Lamma Island in 1996. While Hong Kong remained a relative backwater in early days, nearby Guangzhou (Canton) was developing into a great trading city with connections in India and the Middle East. By a.d. 900, the Hong Kong islands had become a lair for pirates preying on the shipping in the Pearl River Delta and causing a major headache for burgeoning Guangzhou; small bands of pirates were still operating into the early years of the 20th century. In the meantime, the mainland area was being settled by incomers, the "Five Great Clans": Tang, Hau, Pang, Liu, and Man. First to arrive was the Tang clan, which established a number of walled villages in the New Territories that still exist today. You can visit Kat Hing Wai and Lo Wai, villages with their walls still intact. Adjacent to Lo Wai is the Tang Chung Ling Ancestral Hall, built in the 16th century, which is still the center of clan activities. The first Europeans to arrive in the Pearl River Delta were the Portuguese, who settled in Macau in 1557 and for several centuries had a monopoly on trade between Asia, Europe, and South America. As Macau developed into the greatest port in the East, it also became a base for Jesuit missionaries; it was later a haven for persecuted Japanese Christians. While Christianity was not a great success in China, it made local headway, evidenced today by the numerous Catholic churches in Macau's historic center. Intermarriage with the local Chinese created a community of Macanese, whose culture can still be seen in Macau's architecture and cuisine.

Input: The Bush administration did not develop new diplomatic initiatives on al Qaeda with the Saudi government before 9/11. Vice President Cheney called Crown Prince Abdullah on July 5, 2001, to seek Saudi help in preventing threatened attacks on American facilities in the Kingdom. Secretary of State Powell met with the crown prince twice before 9/11. They discussed topics like Iraq, not al Qaeda.U.S.-Saudi relations in the summer of 2001 were marked by sometimes heated disagreements about ongoing Israeli- Palestinian violence, not about Bin Laden. The confirmation of the Pentagon's new leadership was a lengthy process. Deputy Secretary Wolfowitz was confirmed in March 2001 and Under Secretary of Defense for Policy Douglas Feith in July. Though the new officials were briefed about terrorism and some of the earlier planning, including that for Operation Infinite Resolve, they were focused, as Secretary Rumsfeld told us, on creating a twenty-first-century military. At the Joint Chiefs of Staff, General Shelton did not recall much interest by the new administration in military options against al Qaeda in Afghanistan. He could not recall any specific guidance on the topic from the secretary. Brian Sheridan-the outgoing assistant secretary of defense for special operations and low-intensity conflict (SOLIC), the key counterterrorism policy office in the Pentagon-never briefed Rumsfeld. He departed on January 20; he had not been replaced by 9/11. Rumsfeld noted to us his own interest in terrorism, which came up often in his regular meetings with Tenet. He thought that the Defense Department, before 9/11, was not organized adequately or prepared to deal with new threats like terrorism. But his time was consumed with getting new officials in place and working on the foundation documents of a new defense policy, the quadrennial defense review, the defense planning guidance, and the existing contingency plans. He did not recall any particular counterterrorism issue that engaged his attention before 9/11, other than the development of the Predator unmanned aircraft system. The commander of Central Command, General Franks, told us that he did not regard the existing plans as serious. To him a real military plan to address al Qaeda would need to go all the way, following through the details of a full campaign (including the political-military issues of where operations would be based) and securing the rights to fly over neighboring countries. The draft presidential directive circulated in June 2001 began its discussion of the military by reiterating the Defense Department's lead role in protecting its forces abroad.
"What is the last name of the American official who met with Crown Prince Abdullah twice prior to 9/11 to discuss topics like Iraq and Israeli-Palestinian violence?" is "Chenny"?

Input: The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.
"What happens to the energy of an atom if the nucleus is split apart?" is "The energy is released"?
