Article: Scientists from the University of East Anglia have identified four new man-made gases that are contributing to the damage to the ozone layer. Two of the gases are accumulating at a rate that is causing concern among researchers. Worries over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted since the mid 1980s. But the precise origin of these new, similar substances remains a mystery. Lying in the atmosphere, the ozone layer plays a critical role in blocking harmful UV rays, which cause cancers in humans and reproductive problems in animals. Scientists from the British Antarctic Survey were the first to discover a huge "hole" in the ozone over Antarctica in 1985. The evidence quickly pointed to CFC gases, which were invented in the 1920s, and were widely used in refrigeration. Extraordinarily, global action was rapidly agreed to deal with CFCs and the Montreal Protocol to limit these substances came into being in 1987. A total global ban on production came into force in 2010. Now, the newly discovered four new gases can destroy ozone and are getting into the atmosphere from as yet unidentified sources. Three of the gases are CFCs and one is a hydrochlorofluorocarbon (HCFC), which can also damage ozone. The research has shown that four gases were not around in the atmosphere at all until the 1960s, which suggests they are man-made. The scientists discovered the gases by analyzing polar snow pack. Air from this snow is a natural archive of what was in the atmosphere up t0 100 years ago. The researchers also looked at modern air samples, collected at remote Cape Grim in Tasmania. They estimate that about 74,000 tonnes of these gases have been released into the atmosphere. Two of the gases are accumulating at significant rates. However, they don't know where the new gases are being released from and this should be investigated. Possible sources include chemicals for insecticide production and solvents for cleaning electronic... Question: What will the scientists probably attempt to do about the gases next? Yes or no, is the answer "Find out where they are exactly from and stop them from being released."?
No

Q: Article: Almost everyone suffers from a headache occasionally. But some people suffer from repeated, frequent headaches. What is headache? What causes it? What can be done about a headache? What research is being done on headaches? The dictionary defines headache simply as "a pain in the head." What most people mean by headache is a pain which lasts several minutes or hours. It covers the whole head, or one side of it, or perhaps the front or the back of the head. To add to the confusion about a definition, some people call tight feeling in the head a headache. A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early. If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control. The professional name for covering up a symptom is "masking" (,). A headache specialist once said, "Masking symptoms is not the best way of treatment." He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia while bleeding continues undiscovered. He added, "Sometimes it is wiser to stand still than to advance in darkness. A headache is important also because it interferes needlessly with normal, happy living. The employee with a headache does less work. In a flash of temper he may upset his fellow workers or customers, causing a direct of indirect loss to his organization. The mother with a headache suffers and disturbs the family. She upsets her husband and children. Question: What's the main idea of the passage? Yes or no, is the answer "What's a headache and its effect."?
A: No

*Question*
Article: Bali Beach Resort has plenty of attractions. It is a holiday paradise . The self-styled 'Ultimate Island' certainly has plenty for everyone. Where in the world ? Bali is located just off the eastern edge of the main Indonesian island of Java. To the east is the neighboring island of Lombok. To the south of Bali lies the expanse of the Indian Ocean, while to the north is the Bali Sea. The most popular resort with holidaymakers is Ubud north of Sanur. When to go? Bali has a tropical climate year round with an average daily temperature of 31degC(87degCF). The wet season is between October and April. The dry season is between May and September, and is the busiest time to visit the island as travelers take advantage of the long hot days and little rain. Beach Bali has a string of beaches, mainly in the south of the island. Head away from Bali's beaches and a totally different world awaits you. Ubud is an easily accessible jungle resort town with a good range of hotels, shops and restaurants. The active volcano of Mount Batur is a highlight and so are the mountain lakes. Family fun All of the resorts have plenty of facilities for families. In Ubud there is a monkey park, where young ones can see monkeys that are not kept in tiny cages and an elephant park where holidaymakers can ride an elephant. Eating out All of Bali's holiday resorts offer international cooking to suit every tourist's taste, with most of the better hotels having excellent restaurants. Indonesian Bintang beer is very popular. Getting around There are a limited number of local buses. The other public transport is to take the local "bemo" minibuses. These colourful little minibuses speed around the winding roads with fares negotiated on board, so it helps to speak a little of the local language. There are also taxis and both electric bikes and cars can be hired. Question: From the passage we learn that Bali is _ . Yes or no, is the answer "to the west of the Lombok Island"?
**Answer**
No
