Article: A previously unknown kind of human group disappeared from the world so completely that it has left behind the merest piece of evidence that it ever existed -- a single bone from the little finger of a child, buried in a cave in the Altai Mountains of southern Siberia. Researchers removed DNA from the bone and reported that it differed obviously from that of both modern humans and of Neanderthals , living in Europe until the arrival of modern humans on the continent some 44,000 years ago. The child carrying the DNA line was probably 5 to 7 years old, but it is not yet known if it was a boy or a girl. The finger bone was unearthed in 2008 from a place known as the Denisova cave. Researchers are careful not to call the Denisova child a new human species, though it may prove to be so, because the evidence is initial. But the genetic material removed from the bone, found in a layer laid down on the cave floor between 48,000 and 30,000 years ago, belonged to a distinct human line that traveled out of Africa at a different time from the two known ancient human species. Homo erectus , found in East Asia, left Africa two million years ago, and the ancestor of Neanderthals moved away some 500,000 years ago. The numbers of differences found in the child's DNA indicate that its ancestors left Africa about one million years ago. The region was inhabited by both Neanderthals and modern humans at that time. Counting the new human line, three human species may have lived together. The standard view has long been that there were three human resettlements out of Africa -- those of Homo erectus; of the ancestor of Neanderthals; and finally, some 50,000 years ago, of modern humans. But in 2004, archaeologists reported that they had found the bones of small humans who lived on the Indonesian island of Flores until 13,000 years ago, causing a serious problem to this view. The new line is the second such challenge. If the nuclear DNA of the Denisova child should differ as much as its mitochondrial DNA... Question: According to the passage, _ . Yes or no, is the answer "modern humans arrived in Europe about 44,000 years ago"?
Yes

Article: It is commonly known that Japan went from a 19th century national economy to a 20th century global economy in a time span of 30 years between 1945 and 1975. What is less known is that Japan, understanding that fast, efficient transport was the key to a global economy, was the first country in the world to introduce the "Bullet Train". Kawasaki Heavy Industries was duly appointed the manufacturer and the first high speed train went "on line" in 1964. The Shinkansen, as is known in Japan, made its first journey between her capital and Osaka, a distance of 301 miles, at a speed of 132 mph. The next country to introduce high speed trains was France. SNGF, the public rail system in France, was losing passengers to other forms of transport and introduced the "TGV" (Train a Grande Vitesse) to counteract the trend in 1981. As a result of Opec controlling the oil market in 1974, the train was designed to be powered by gas turbines. It ran on a specially built track between Lyon and Paris. Eight years later another TGV was introduced, this time between the coast and Paris. Soon, France became the most rail efficient country in the world with high speed train connections to Belgium, London, Germany, Switzerland, Spain and the Netherlands. There was another positive element that resulted from the introduction of high speed trains. Between 1964 and 1991, Japan's Shinkansen had transported in excess of three billion passengers without there being a single fatal accident and eleven years after France introduced the TGV, it still had a 100% safety record. This statistic has never been equaled by the traditional slow moving trains in any country. China has become the fourth country to produce such trains, after France, Germany and Japan. China's first domestically produced bullet train with a maximum speed of 350 kilometers per hour has rolled off the production line. Equipped with highly-efficient power system, the currently fastest train in China is also energy efficient. When the train is running, it can transfer kinetic... Question: Which of the following advantage(s) belongs to bullet train? Yes or no, is the answer "Fast and safe."?
No
