Write a multi-choice question for the following article, with the given choices and answer: Article: Cut out part of a healthy person's liver and transplant it into a sick person--it sounds like a complicated and dangerous operation , not to mention very expensive. But it is sometimes the only possible cure for a seriously ill patient with liver disease. Until now British scientists have just announced a new stem cell technique, which allows them to grow healthy liver cells outside human bodies. According to the researchers, it could be another five to ten years before the technique can actually be used to help patients with liver disease. However, they say the method might one day replace liver transplants altogether. The study was led by the University of Cambridge and the Welcome Trust Sanger Institute, a British genomics and genetics research institute. It was published in the journal nature on October 12,2011. The researchers took skin cells from a patient with a mutation in a gene called alphal-antitrypsin (a-l). This gene makes a protein that protects our bodies against inflammation . People with changed or damaged alphal-antitrypsin are not able to release the protein correctly from the liver, so the protein is trapped there and eventually leads to liver cirrhosis . Scientists then used an advanced technique to cut away the faulty section of DNA from a stem cell and replace it with a corrected one, according to the journal. The stem cells went on to produce fresh and healthy liver cells with normal protein levels. Scientists put the new liver cells into mice and found that they worked very well. Stem cells are the life source of all other cells in the body. They could transform medicine, providing treatment for blindness, spinal cord injuries and other serous injuries. They could also be used to produce new cells for damaged organs. David Lomas, a Cambridge biology professor who worked on the team, said: "If we can use a patient's own skins cells to produce liver cells that we can put back into the patient, we may prevent the future need for transplantation. " Options: A Because their bodies are lacking in alphal-antitrypsin. B Because their skin cells are not able to protect against inflammation. C Because the alphal-antitrypsin in their bodies is changed or damaged. D Because their liver releases too high a level of protein. Answer: C Because the alphal-antitrypsin in their bodies is changed or damaged. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: The type of things we remember are different. Although we tend to remember good things in our lives, bad things have a way of on us. One such thing I remember happened when I was 10 years old. I decided to ride my bicycle over a near-by stream. I carefully planned the adventure, and asked my friends to go there and have a watch. This was going to be my moment! I started riding down the hill, picking up speed and then pulled up on the at the precise moment and landed face-first into the muddy stream! That painful moment is one that I will never forget. As long as I live, I will remember the pain and embarrassment at that moment. When we do something stupid or thoughtless, it has a way of sticking with us. Fortunately, good momories have a way of over-riding the bad ones. I have memories that I gladly remember, like what happened today. I had my first conversation with my son today. It was not anything . It was a simple connection between father and son. It was one of those bonding moments that you can't plan or force. They just happen on their own. I was walking into the living room where my son sat in bed watching television attentively. Then he looked up at me and pointed to the television and something. I asked him if he was watching and he nodded his head and said,"Yes". It was at that moment that his eyes lit up and it was as if we both realized we had communicated. And how happy I was! Sure, at eighteen months, he probably did not realize what communication was like, but his joy at that moment was evident. It was a moment I will remember all my life. Good or bad, memories can last a lifetime. As for an unpleasant memory, though we can't forget it we can get lessons from it and it is like a mirror that will warn us against making such mistakes again. As for a good memory, we should try our best to enjoy it during our lifetime. Such moments are the treasures that we store up forever. Options: A Because his son respected the author and was very understanding. B Because it was the fist time he communicated with his little son. C Because his little son didn't make trouble and behaved quite well. D Because his son could understand the meaning of Answer: B Because it was the fist time he communicated with his little son. Question:
A: Why was the author so happy when hearing his son's answer "YES"?

Write a multi-choice question for the following article, with the given choices and answer: Article: Teary Joe was a boy with a special ability: he could make himself cry in less than a second. If he disliked something, or things became difficult, Teary Joe would not hesitate to put on a pitiful face and set great big tears running down his cheeks. In this way he managed to get practically everything he wanted, because no one could resist the pity inspired by his tearful little face. But one day, Teary Joe met Pipo. Pipo was asking people in the street for some change, in return for him helping them in any way he could. Pipo was very poor; he had no home and no family, so he made a living however he could. Even so, Pipo always had the biggest smiles on his face. Joe took to Pipo, so he decided to help him out in making some money. He went over next to Pipo, took off his hat, put it face-up on the ground, and started crying with the most pitiful of expressions. Ina few minutes, Joe's hat was full of coins and sweets, but when Joe offered all this to Pipo, Pipo declined. "I prefer deserving what I receive," answered Pipo with his usual smile, "It's much more fun making an effort to get things. Maybe I haven't gotten everything I've wanted, but I've done a load of interesting things." Teary Joe didn't answer; he just walked sadly away. Joe had got everything he wanted, but he'd done practically nothing of interest the whole day. That evening, having returned home, Joe requested a delicious cake for his supper. When his mother said no, Joe tried to cry but, remembering Pipo and how joyful he was, he tried to get the cake in some other way. Joe spent the whole evening helping his mother to water the plants and organize the library books. In the end there was no cake. But that wasn't so bad, because Joe discovered it had been much more fun doing all those things that evening rather than just sitting crying to get a piece of cake that, in the end, wouldn't have been worth it. Options: A considered that Pipo was very poor B realized he shouldn't change his life style C didn't get delicious cake for supper D got everything he wanted without delight Answer: D got everything he wanted without delight Question:
