Centuries ago, however, crossing the open seas required thorough and accurate planning, handmade boats, and courage. Scientists and historians have long been looking for clues to explain who crossed which oceans first. When it comes to the trip between Polynesia and South America, chickens may have been among the first ocean voyagers, according to new evidence. After studying an ancient chicken bone, anthropologists from the University of Auckland in New Zealand now say that people and chickens traveled from Polynesia to what is now Chile by about 620 years ago. By then, the Inca people were already living in South America, but the Polynesians would have been the first to get there by sea. Previous theories claimed that European explorers and their chickens sailed to South America first -- but those voyagers didn't arrive until about a century later. In 2002, archaeologists dug up 50 chicken bones from a site in Chile called El Arenal. The team from New Zealand analyzed one to these bones. According to their calculations, the bone is about 650 years old. The researchers also compared the genetic material, or DNA, from the South American chicken bone with DNA from 11 chicken bones that had been found on the Polynesian islands of Tonga and American Samoa. These islands are 6,000 miles west of Chile. The bones found on the Polynesian islands are been 600 and 2,000 years old. Results of the comparisons showed that the chicken bones from both the Polynesian and South American sites had part of DNA in common. The researchers found the same part of DNA in feathers of two living chickens in Chile that belong to a modem breed that lays blue eggs. That DNA evidence suggests a close relationship among the chickens. "However, the weight of scientific evidence is now behind the hypothesis that it was seafaring ( ) Polynesians who sailed from the islands to South America and returned," says archaeologist Patrick V. Kirch of the University of...

Please answer this: Write a multi-choice question for the following article: Article: The oil from palms has a wide variety of uses and is found in food, soaps and shampoos. An international team found a gene that made some of the trees produce more oil than others. Dr Rajinder Singh, from government agency the Malaysian Palm Oil Board, said, "The oil palm has three fruit forms: a thick-shelled type --the Dura; those that don't have any shell--the Pisifera; a third form produced as a cross between the thick shell and the one without the shell--the Tenera, which are more of the fleshy fruit to produce the oil," and the researchers identified the gene producing this trait. While oil palm growers attempt to grow only the thin-shelled Tenera variety, up to 10% of the seeds can be contaminated , and turn out to be the other less oily plants. Prof. Martienssen, from the Cold Spring Harbour Laboratory, said, "We can now use that gene in genetic testing, which will allow growers as well as producers to know exactly what sort of tree they are planting before it produces fruit. It takes a long time for these trees to produce fruit, but by being able to predict exactly what sort of fruit that trees will produce, it will greatly assist growers." The researchers say this could offer a more sustainable form of agriculture. Prof. Martienssen said, "This finding gives us huge hope. We hope to maximize land usage and produce a lot more on the same amount of land, because we do not want to destroy the rainforest any more." However, the environmental group WWF-UK said that the global demand for oil palm was growing rapidly, making the expansion of plantations inevitable. Adam Harrison, the organization's food and agriculture policy officer, said, "In a sense it does not matter if a 'good' variety replaces forest or a 'bad' one, the wildlife and communities that need access to that land will suffer. So for palm oil to be sustainable, the process of allocating land needs to be controlled. There is an abundance of low-carbon, low-wildlife and conflict-free land available and there is no more need for forest...

input question: Write a multi-choice question for the following article: Article: The English language is the result of the invasion of the island of Britain over many hundreds of years.The first invasions were by a people called Angles about 1, 500 years ago. The Angles were a German tribe who crossed the English Channel . Later two more groups crossed to Britain. They were the Saxons and the Jutes. Through many years, the Saxons, Angles and the Jutes mixed their different languages. The result is what is called Anglo-Saxon or old English. The next great invasion of Britain was done by Vikings about 1, 100 years ago. Many English words used today come from these ancient Vikings. The next invasion of Britain took place more than 900 years ago, in 1066. History experts call this invasion the Norman Conquest. The Normans were a French-speaking people from Normandy in the north of France. These new rulers spoke only French for several hundred years. It was the most important language in the world at that time. It was the language of educated people. But the common people of Britain still spoke old English. Old English took many words from the Norman French. Some of these include "damage", "prison", and "marriage". The French language used by the Norman rulers greatly changed the way English was spoken 800 years ago. English became what language experts call Middle English. Middle English sounds like Modern English. But it is difficult to understand now. The history of the English language continues as Middle English becomes Modern English, which is spoken today.???
