[Q]: 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.
[A]: Which of the following is true about Beijing's Sinovac Biotech Ltd?


[Q]: Article: Deng Nannan, 15, used to hate drinking milk for breakfast. But she had to drink it because her mom, as well as many others, said that milk was good for her growing body. Besides, milk and bread made up a convenient diet that saved her parents a lot of time after Deng entered junior school and had to arrive at school early in the morning. After that, Mengniu and Yili became her favorite brands of morning milk and yoghurt after dinner. However, she has been forced to change her diet since the recent milk crisis. Many best-selling milk brands such as Mengniu, Yili and Bright were discovered to contain melamine  , which is usually used to make plastic. The bad milk products have sickened more than 5,300 babies and killed four. "I shifted to rice porridge," she said. "My mom has to get up at 5:50 am to prepare my breakfast and make sure that it cools down when I get up." Deng has become addicted to milk, so she doesn't quite enjoy her morning meal these days although she knows that it's a tiring job for her working mom.  "I'll turn back to Mengniu and Yili when they finally improve their products," she said.   However, right now Deng's mom tries to adjust   her eating habits by cooking different foods. Besides rice porridge, noodles, egg soup and soybean milk are prepared as her breakfast. 
 Answer: Because milk becomes more and more expensive.
[A]: According to the passage, why do some students stop drinking milk?


[Q]: Article: In the Arctic Ocean waters live the social animals---belugas, which is also known as white whales. Highly intelligent, these whales use different sounds to communicate and find their way. Belugas are also among the smallest kinds of whales. More than 210 belugas, including 31 in the United States, live in aquariums   around the world. The Georgia Aquarium has asked for permission to bring 18 more belugas into the U.S. The whales were caught off the coast of Russia. The National Oceanic and Atmospheric Administration (NOAA) is considering the aquarium's request thoroughly. A law called the Marine Mammal Protection Act (MMPA) says the animals can only be brought into the country and put on display if they are caught without being hurt and there is an educational reason for doing so. Georgia Aquarium officials say the 18 belugas will help people learn more about the species and allow scientists to better understand how to protect it. The aquarium would also breed the whales so the U.S. aquariums can continue to display them. "When we can study and observe, we gain a better understanding of their biology and diseases that affect them, and learn how to aid populations in their natural habitats," says William Hurley, Georgia Aquarium's chief officer. "Much of this research would be impossible in the remote locations and extreme climates where the animals live." The Georgia Aquarium would own the 18 belugas and would rent some to aquariums across the country. Meanwhile, many scientists, including Lori Marino, a whale expert, feel strongly that the whales belong in the ocean, not in tanks. These scientists say the whales are being used for entertainment and not for education, and having them in aquariums is not necessary for the species to survive. Marino said, "Not only is it unfair to the belugas but there is no educational value in putting these whales on display." 
 Answer: They are the smallest in number.
[A]:
What can we learn about belugas?
