Question: Article: When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved . "
Answer: They cure diseases by changing chemicals

Answer: What is the function of the " proteinase inhibitors " in tomato plants ?

Question: Article: We sometimes think global warming or climate change is a problem very far away from our lives, and that only the government needs to worry about it. But it's hardly possible to completely stay out of it scientists are now 95 percent sure that humans have been the " cause" of global warming trends since the 1950s. One of the conclusions of a report released on Sept 27 by the United Nations says that human activities have caused global temperatures to rise by 0.89 0C between 1901 and 2012. That might not seem like a lot, but the truth is that a major part of that heat has been absorbed into the oceans, which is not surprising given that they cover two thirds of Earth's surface. Also, water has a much greater capacity to absorb heat than the air does, according to The Economist. While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life, humans' use of fossil fuels is the main source of excess greenhouse gases. According to CNN, by driving cars, using electricity produced by burning coal and oil or heating our homes with coal or natural gas, we release a large amount of greenhouse gases into the atmosphere. Your body can barely feel a difference of 0.89 0C, but the Earth's ecosystems are so sensitive that even small changes can disturb them. It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct. Global warming is also linked to an increase in extreme weather. A larger amount of carbon dioxide traps more energy inside the atmosphere. This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods. Worse still, melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year, according to The Guardian, which also increases the risk of flooding. "The report should serve as another wakeup call that our activities today have a profound impact on society, not only for us, but for many generations to come," French Michel Jarraud, secretarygeneral of the World Meteorological Organization, said at a news conference.
Answer: The hugeness of oceans makes them better absorbers of heat than the air.

Answer: Which of the following statements is TRUE according to the passage?

Question: Article: The head of the World Health Organization (WTO) yesterday warned of worsening health in the country's vast rural areas while praising the government for its commitment on improving healthcare in the countryside. "The health indicators have failed to improve in pace with economic indicators." said Margared Chan when addressing a conference on rural primary healthcare in prefix = st1 /China. "The health gap between rural and urban areas has grown even wider and health in parts of rural China is deteriorating ,"she said, adding medical costs are rising faster than the growth of per capital income in rural areas. She said she appreciated the government's efforts and plans to build a medical system for all people. Saying "when fair and accessible public health services become the clear targets of a country's public health policy, people's health will improve." The WTO chief said she noticed that the tasks on improving people's well-being in the report by Party chief Hu Jintao at the 17thNational Congress of the Communist Party of China included a basic medical insurance system for urban dwellers and a cooperative medical care system in rural areas. She said recent WTO research has found that diseases are the source of poverty for 30 to 50 percent of the rural population of 737 million. A growing number of rural people, especially the aged, are suffering from various diseases; however, few have access to decent healthcare, she told the conference. Chan criticized the practice of allowing healthcare services to be commercialized in rural areas, warning it will cause the patients more suffering. The government has pledged to provide its population with basic medical care by 2020. It's expanding medical care through the Rural Cooperative Medical Scheme, a plan under which subscribers are provided with 50 yuan($6.4) per person--20 yuan ($2.6) each from the central and local governments and 10 yuan ($1.3) from the individual. Vice-Minister of Health Chen Xiaohong said nearly 85 percent of the country's rural area, or 2,429 counties, are participating in the plan.
Answer: Healthcare developed more slowly than economics.
