In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Q: Article: Chinese scientists have found a new way to use cells found in human urine that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells. The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders. Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial cells in urine into NPCs. These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said. "These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient". Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said. Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases." "It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
Answer: Chinese scientists succeeded in making NPCs from human urine.

Q: Article: The people who built Stonehenge in Southern England thousands of years ago had wild parties, eating barbecued pigs and breaking pottery. This is according to recent work by archaeologists--history experts who investigate how human beings lived in the past. Archaeologists digging near Stonehenge last year discovered the remains of a large prehistoric village where they think the builders of the mysterious stone circle used to live. The village is about 4,600 years old, the same age as Stonehenge and as old as the Pyramids in Egypt. It is less than two miles from the famous ancient landmark and lies inside a massive man-made circular dirt wall, or "henge", known as the Durrington Walls. Remains found at the site included jewellry, stone arrowheads, tools made of deer antlers, wooden spears and huge amounts of animal bones and broken pottery. "These finds suggest Stone Age people went to the village at special times of the year to feast and party", says Mike Parker-Pearson from Sheffield University in England. He said many of the pig bones they found had been thrown away half-eaten. He also said the partygoers appeared to have shot some of the farm pigs with arrows, possibly as a kind of sport before barbecuing them. An ancient road which led from the village to the River Avon was also found. Here, the experts think, people came after their parties to throw dead s in the water so the bodies would be washed downstream to Stonehenge. Parker-Pearson believes Stonehenge was like a cemetery where ancient Britons buried the dead and remembered their ancestors. The theory is that Stonehenge is a kind of spirit home to the ancestors. The recent discovery of the village within the Durrington Walls shows that Stonehenge didn't stand alone but was part of a much bigger religious site, according to Parker-Pearson.People still come to worship and celebrate at Stonehenge today. They meet there when the sun sets on the shortest day of winter and when it rises on the longest day of summer. But the days of barbecuing whole pigs there and throwing family members into the river are a thing of the past. At present, it has been attracting a great number of visitors all around the world. Here is a comment from a visitor. "I am speaking to a friend on Facebook who is heartbroken that she went there with utter love and respect for the site and that the whole Summer Solstice event was full of drunk party goers and those that had gone in a respectful, loving way were made to sit on the outside, so as not to be disturbed by the revellers."
Answer: A site where dead people were placed or remembered.

Q: Article: Siberia is a huge territory in Russia. It is more than half of Russia and is 4,000 miles wide. Most of this area is a forest with animals and birds. In autumn, the forests in Siberia are full of mushrooms and berries . Many people like picking mushrooms, but that is not as simple as you might think. Old people who live in the villages know places where you can pick lots of mushrooms. Some mushrooms grow in colonies. If you find one, you only need to look around because nearby you'll find more of them. However, when picking mushrooms, it is important not to choose the wrong kind. You have to be careful because some mushrooms are poisonous even though they look good. The smell can help you choose them, because good mushrooms smell very good. Siberian people are very friendly and hospitable. If someone invites you home for dinner, you'll soon be full. You should try everything the host is having. The climate there depends on the territory. Some places have very comfortable climates with hot summers and cold winters. In my opinion, the best season is spring, when nature wakes up after a long winter. It is the time for blossoms and love. Birds come back from other warm countries. Trees become dressed in green. The sun becomes warm and the days are longer. The mood is wonderful and people smile a lot. It is an amazing time. In winter, you have opportunity for sports. The most popular sport in winter in Russia is cross-country skiing. During weekends, many people go into the country and ski. Noses freeze and cheeks hurt, but people continue to enjoy these times.
Answer: Siberia, an interesting and beautiful place.
