Article: NANJING -- Another human H7N9 case has been found in east China's Jiangsu Province, the provincial health department confirmed on January 31. The patient, a 75-year-old woman from the provincial capital of Nanjing, is in a critical condition. The case brings the number of infections in the province to eight this year. H7N9 has killed 19 in China this year, and the total number of human infections reached 96 on January 26, according to the Chinese Center for Disease Control and Prevention. With bird flu cases increasing on a daily basis, public concern over people-to-people transmission during Spring Festival is growing. Li Lanjuan, researcher at the Chinese Academy of Engineering and a specialist in H7N9 prevention, said so far there have not been any cases in which one person transmits the flu to another, and the latter transmits the virus to a third person. Her team has identified H7N9 virus mutations this year, but the _ are not large-scale. "Inter-human transmission is very unlikely," said Li, who added that the virus has not evolved to be extensively drug resistant. The National Health and Family Planning Commission said on Wednesday live poultry markets should close if any case of H7N9 avian flu is detected. The southern metropolis of Shenzhen has closed all live poultry markets until February 13 for a thorough cleaning. The city near Hong Kong has reported 14 human H7N9 cases since December 18. Live poultry trading has been halted in Hangzhou, Ningbo and Jinhua cities in Zhejiang, which reported the largest number of human H7N9 cases. China has stepped up research for an H7N9 vaccine in the face of the increasing threat from the virus. Beijing's Snovac Hotech Ltd.,which developed the A/H1N1 and H5N1 vaccines, said in a press release on Wednesday that it has completed preclinical studies of an H7N9 vaccine arid prepared several types for clinical testing. The company has submitted an application to the China Food and Drug Administration to start clinical trials.
Answer: It once developed the A/H1N1 and H5N1 vaccines.
Which of the following is true about Beijing's Sinovac Biotech Ltd?

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.
What is the passage mainly about?

Article: Mr. Hungerton, her father, really was absolutely centered upon his own silly self. If anything could have driven me from Gladys, it would have been the thought of such a father-in-law. I am convinced that he really believed in his heart that I came round to the Chestnuts three days a week for the pleasure of his company, and very especially to hear his views upon bimetallism . For an hour or more that evening I listened to his tiring talk about bad money driving out good, and the true standards of exchange. "Suppose," he cried, "that all the debts in the world were called up at once, and immediate payment insisted upon,--what under our present conditions would happen then?" I gave the self-evident answer that I should be a ruined man, upon which he jumped from his chair, scolding me for my thoughtless quickness, which made it impossible for him to discuss any reasonable subject in my presence. At last I was alone with Gladys, and the moment of Fate had come! She sat with that proud, delicate figure of hers outlined against the red curtain. How beautiful she was! Gladys was full of every womanly quality. I was about to break the long and uneasy silence, when two critical, dark eyes looked round at me, and the proud head was shaken disapprovingly. "I have a feeling that you are going to propose, Ned. I do wish you wouldn't; for things are so much nicer as they are." I drew my chair a little nearer. "Now, how did you know that I was going to propose?" I asked in wonder. "Don't women always know? Do you suppose any woman in the world was ever taken unawares? But--oh, Ned, our friendship has been so good and so pleasant! What a pity to spoil it! Don't you feel how splendid it is that a young man and a young woman should be able to talk face to face as we have talked?" She had sprung from her chair, as she saw signs that I proposed to announce some of my wants. "You've spoiled everything, Ned," she said. "It's all so beautiful and natural until this kind of thing comes in! It is such a pity! Why can't you control yourself?" "But why can't you love me, Gladys? Is it my appearance, or what?" "No, it isn't that." "My character?" She nodded severely. "What can I do to mend it?" She looked at me with a wondering distrust which was much more to my mind than her whole-hearted confidence. "Now tell me what's amiss with me?" "I'm in love with somebody else," said she. It was my turn to jump out of my chair. "It's nobody in particular," she explained, laughing at the expression of my face: "only an ideal. I've never met the kind of man I mean." "Tell me about him. What does he look like?" "Oh, he might look very much like you." "How dear of you to say that! Well, what is it that he does that I don't do? I'll have a try at it, Gladys, if you will only give me an idea what would please you." "Well, it is never a man that I should love, but always the glories he had won; for they would be reflected upon me. Think of Richard Burton! When I read his wife's life of him I could so understand her love! And Lady Stanley! Did you ever read the wonderful last chapter of that book about her husband? These are the sort of men that a woman could worship with all her soul, and yet be the greater, not the less, on account of her love, honored by all the world as the inspirer of noble deeds." "And if I do----" Her dear hand rested upon my lips. "Not another word, Sir! You should have been at the office for evening duty half an hour ago; only I hadn't the heart to remind you. Some day, perhaps, when you have won your place in the world, we shall talk it over again."
