Q: 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 scribes — China'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. <sep>During the Shang Dynasty, the Chinese developed an interest in what type of designs?<sep>Careful geometric designs

A: Yes

Q: (CNN) -- Tito Joseph "TJ" Jackson, who on Wednesday was named temporary guardian of Michael Jackson's three children, was inspired by his famous uncle to form a singing group with his brothers. TJ had been placed in charge of the children when the kids' grandmother, Katherine, left home on July 15 and will watch the children while the legal proceedings play out in a California court. TJ Jackson, 34, is the son of Tito Jackson and the late Delores Martes Jackson. TJ and his older brothers, Taj and Taryll, form the R&B group 3T. Jackson is married with three children, a boy and two girls. Judge suspends Katherine Jackson as guardian of Michael Jackson's children A 1995 article in People described the brothers' childhood as normal despite their famous father, uncle and aunts. Taj Jackson told the magazine: "My mom made sure that we had a real childhood, with birthday parties, baseball, family outings, all that stuff." They were close to their Uncle Michael. "He's like a third parent to us," Taj told People in 1995. Eventually the brothers went along on one of his tours and decided to form a singing group and were recording their first album in 1994 at the time of their mother's death. Initially it was believed Delores Martes Jackson, who had divorced from Tito Jackson in 1993, drowned in a swimming pool, but the case was reopened, and her sons in 1995 filed a wrongful-death lawsuit against a man they accused of killing her. Three years later, Donald Bohana was convicted of second-degree murder and sentenced to 15 years to life in prison, according to People magazine. <sep>Who is the brother of Tito Jackson?<sep>Tiju

Q: Hurlburt Field, Florida (CNN) -- An Air Force CV-22 Osprey crashed Wednesday during a routine training mission north of Navarre, Florida, injuring five crew members aboard, a military official said. The crash occurred about 6:45 p.m. at Hurlburt Field's Eglin Range, said Amy Nicholson, chief of public affairs at the airfield. The five injured crew members were taken to an area hospital, Nicholson said. The extent of their injuries was not immediately known. The cause of the accident is under investigation, she said. The Osprey was assigned to the 1st Special Operations Wing, the Air Force said. The tilt-rotor aircraft can fly like an airplane and land like a helicopter. The Army began developing the Osprey in 1982, though the program was nearly scrapped in 1989 when then-Secretary of Defense Dick Cheney sought to cancel it because of ballooning costs. Questions were raised about the safety of the Osprey after two crashes, including one in 1992 at a Marine Corps air base in Virginia that killed the crew. In late 2000, the Marine Corps grounded the Osprey fleet after two crashes -- one in Arizona that killed four crew members and 15 passengers, and another in North Carolina that killed the crew. A redesign was ordered on the Osprey, and it resumed flights in 2002. The Air Force began using Ospreys in 2008 after testing the aircraft in 2006. They were first deployed by the Marines in Iraq in 2007 after 18 years and $20 billion in development. <sep>When the Marines deployed the Osprey, how long had it been in development?<sep>25 years

No
