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.
answer:
Which of the following is true about Beijing's Sinovac Biotech Ltd?

Article: Maybe you don't know the fact that the green forests we see from an airplane or from the highway can be false. Because centuries ago forests were twice as many as what they are today. A hike into many of those woods will tell different stories, too--of diseases and insects that are slowly killing trees, of some forests that are burned by fire, of logging that local people do more often. Deforestation and degradation of the world's forests mainly harm the basic ability of those ecosystems to function or provide services, such as fresh water, air, plants and animals, which benefit people everywhere and keep the balance of nature. Deforestation Forests today are a small part of what they once were. Nearly half of the world's forest cover is gone, and each year 40 million acres more are cut and replaced by agriculture and development. Over the next 45 years, wood use in the world is guessed to increase by 50 per cent over its present rate. Many of the forests that remain are severely destroyed, which harms the ability to protect birds or wild animals, and to supply natural resources to people. Deforestation also brings about between 20 per cent and 25 per cent of all air pollution causing global climate change. Degradation Forests continue to be degraded by some uses such as the gathering of wood for fuel, the arrival of pests and diseases that kill trees, the effects of climate change and poor management such as the fire, flood and so on.
Answer: The ability of the ecosystems to function.
answer:
What do deforestation and degradation of the forests mainly harm?

Article: The largest outbreak of the deadly disease Ebola was caused by an infected bat biting a toddler, say a group of international researchers. The 17-strong team of European and African tropical disease researchers, ecologists and anthropologists have spent three weeks investigating the outbreak of the disease in Guinea, Liberia, Ivory Coast and Nigeria. The researchers captured the bats and other creatures near the village of Meliandoua in remote eastern Guinea, where the disease began in December 2013. The boy was bitten and passed the infection on to his mother and both died within a week. The disease was then spread far and wide by the people who came to the funeral. Most of the previous outbreaks have been caused by meat from dead infected animals collected by hunters who then sell it on. Fruit bats, however, are widely eaten in rural West Africa. The team, led by epidemiologist Herr Leendertz, a disease ecologist at the Robert Koch Institute in Berlin, are expected to publish their results in a major journal soon. Herr Leendertz's team believe that an infected straw-colored fruit bat brought the disease to Guinea. The mammals are known to travel long distances and usually settle in forests near cities. Herr Leendertz said, " The evidence is not 100 percent and we can only say that it is possible. They can travel far in one night. I don't think an individual bat or colony migrated all the way from Congo or Gabon to West Africa. These big colonies are connected. There is a possibility for the virus to mix between colonies. The bats share the same fruit. It is likely not to have even been one species of bat. The virus may jump from one species to another." If the bat theory is confirmed, the locals would try to destroy the colonies, which, Herr Leendertz says, would be an ecological disaster, because bats pollinate plants and kill insects. And bat hunts would also only increase human contact with potentially infected animals.
Answer: To look into the outbreak of Ebola.
answer:
What's the purpose of the 17-strong team?
