I'm taking a test and have to guess the right answer to the question after the article. Article: The quality of water supply in southern Beijing has been improving in recent years, an official said. In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform. "The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said. In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said. Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing. Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances, he said. According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants. The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said. The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said. Many new communities in southern Beijing are equipped with a network to recycle water. In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it. Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015. Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely... Question: Which is the best title for the passage? Options: A: Beijing government has taken measures to improve its people's life. B: Recycled water flows to southern Beijing. C: More recycled water plants will be built. D: The southern Beijing residents will enjoy clean water

I'm taking a test and have to guess the right answer to the question after the article. Article: How to Tell If Someone Is Happy or Sad on the Phone Scientists have come up with some researches on what makes different types of people"tick". The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad. Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions--it will also use a GPS tracking system to log where the call is made. _ The results from the pilot scheme make interesting scientific reading. Among the key revelations (=facts) are that callers feel happier at home and sadder at work. To break it down, scientifically, it shows 45 percent of all emotions produced at home are "happy"and 54 percent of emotions at work are "sad". Meanwhile, people show more "intense"(=nervous) emotions in the evening than they do in the morning. Of course, this could just be because most people feel too tired in the morning to get overly "intense". Eating breakfast and getting to work on time is usually enough of an achievement. Anyway, the Emotion Sense technology has been developed by psychologists and computer scientists who say it uses speech recognition software and phone sensors attached to standard smart phones to judge how callers' emotions are changed by everyday factors. The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral---boredom or passivity would fit into this last category. Question: Why do most people feel less intense in the morning than in the evening? Options: A: Because morning is the start of a new day. B: because they feel too tired in the morning. C: Because of humans' physiological structure. D: Because of the fresh air and bright sunlight.
