Hundreds of thousands of years before China was to become the world's longest-running civilization, the prologue was enacted by means of the flicker of a carefully tended fire. Peking Man, a forebear of Homo sapiens, achieved a mastery of fire. We might call it the first Chinese invention. Not that he devised flint and steel, matches, or any other way of creating fire. Peking Man simply learned how to capture flame, perhaps from a forest fire, and keep it alight. He thus enjoyed two revolutionary luxuries: light and heat. Technologically and sociologically, it was a phenomenal breakthrough: with fire, communities could live year 'round in one cave, in which cooking and even smelting could be pursued. And so, by 600,000 b.c., about 50 km (31 miles) southwest of present-day Beijing, the ancestors of mankind were ready to settle down. Several hundred thousand years later, when Marco Polo reached the capital of China, he was astonished by a further development in fire technology. The Chinese, he announced, used black stones dug out of mountains as fuel. Europeans did not yet have a word for "coal," nor had they discovered a use for it. The First Dynasty The confluence of mythology and history in China took place around 4,000 years ago during what is referred to as the Xia (Hsia) Dynasty. This was still the Stone Age, but the people are thought to have made silk from thread produced by the worms they cultivated on the leaves of their mulberry trees. And written language (which evolved as early as 4,500 to 5,000 years ago) was already in use, originally by oracles and then by official scribesChina's first scholars. During the second of the quasi-legendary dynasties, the Shang (from about the 16th to 11th centuries b.c.), the Chinese developed an interest in art. Careful geometric designs as well as dragon and bird motifs adorned bowls and implements. And with the arrival of the Bronze Age, the Chinese created bronze vessels of such beauty and originality that, until modern times, archaeologists refused to believe they were cast 3,000 years ago. The Shang Dynasty gave rise to the concept of one Chinese nation under one government.

New York (CNN) -- Three defendants pleaded guilty in federal court Wednesday to conspiring to defraud a Holocaust reparations organization out of $57.3 million, according to court documents. Genrikh Kolontyrskiy, Moysey Kucher and Dora Kucher, all of Brooklyn, helped produce and process some of the thousands of fraudulent applications for the Conference on Jewish Material Claims Against Germany that are under investigation. The organization, also known as the Claims Conference, distributes more than $400 million a year from funds provided by the German government to victims of the Holocaust. "Our efforts to hold to account all of the individuals who participated in defrauding an organization that exists solely for the purpose of aiding victims of Nazi atrocities continues," said Preet Bharara, U.S. Attorney for the Southern District of New York, in a statement. The defendants aided in defrauding two funds managed by the Claims Conference, the Article 2 Fund and the Hardship Fund, of $45 million and $12.3 million, respectively, according to court documents. The Article 2 Fund makes monthly payments of around $400 to survivors of Nazi persecution who make less than $16,000 per year "and either lived in hiding or under a false identity for at least 18 months," according to a news release from the U.S. Attorney's office. The Hardship Fund pays a one-time payment of $3,500 to "victims of Nazi persecution who evacuated the cities in which they lived and were forced to become refugees." Kolontyrskiy, 80, knowingly processed fraudulent applications for payment while employed with the Article 2 Fund, according to court documents. Moysey Kucher, 66, and Dora Kucher, 58, recruited individuals to provide identification documents that were used to prepare fraudulent applications for both funds, in exchange for money paid out to the false applicants, according to court documents. Jesse Siegel, Kolontyrskiy's attorney, said his client was by no means a major instigator, but he takes responsibility for his actions.

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.

Question: "Where did Atta and Oari travel from, and where did they travel to?"

OPTIONS:

Answer: "Boston, Prtland"
