Article: Tour Inside a Volcano in Iceland Operation dates: From June 15th -July 31st Departure times: 8:00 AM / 10:00 AM /12:00 PM / 14:00 PM. Duration: 5-6 hours (up to 1 hour inside the volcano) Fitness level needed: Average. No knowledge of hiking or climbing is needed. Distance Walked: About 2.5 km (1.7 miles) each way. Age limit: 12 years Included: Pick-up at your hotel in Reykjavik All safety equipment Soup, coffee/tea and perhaps some sweets as well Transfer back to Reykjavik Bring with you: Good shoes. Sneakers will work, but we don't recommend them. Water. The walk over the lava field is a good workout! Outdoor clothing. Dress according to weather for the walk. A warm sweater or a jacket would be useful. About the tour: This volcano tour takes you inside a volcano, through the top crater and down to the bottom of its magma chamber . The Thrihnukagigur volcano has not erupted for 4,000 years and shows no signs of coming to life again anytime soon. Hence, you are safe! You depart from Reykjavik and drive to the area of Blafjoll mountains (About 30 minutes' drive). From there, an easy 35- to 40-minute walk awaits you, in order to get to the volcano. Using a system normally used to carry window cleaners outside skyscrapers, you will go down 120 metres in an open elevator, a basket lift that is supported by cable wires. The group is split into smaller parties of four to five persons. The trip takes about 10 minutes and the first ones to go down will be the first ones to go up. After exploring the volcano on the inside, you will walk back over the lava field where the coach awaits and transfers you back to Reykjavik. Question: The text is most probably taken from _ .

Article: Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip. But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service. Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, "In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off." Question: This passage is mainly about _ . Yes or no, is the answer "the origin and present meaning of tipping"?
Yes

Q: Article: How often do you sit still and do absolutely nothing.The usual answer these days is"never".or"hardly ever".As the pace of life continues to increase,we are fast losing the art of relaxation.Once you are in the habit of rushing through life,being on the go from morning till night,it is hard to slow down.But relaxation is essential for a healthy mind and body. Stress is fl natural part of everyday life.There is no way to avoid it, since it takes many and varied forms-driving in traffic,problems with personal relationships are all different forms of stress. _ .A certain amount of stress is vital to provide motivation and give purpose to life.It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can withstand depends very much on the individual.Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities.Others lose heart at the first sight of unusual difficulties.When exposed to stress,in whatever form,we react both chemically and physically.In fact we make a choice between "fight" or "fright" and in more primitive days the choice made the difference between life and death.The crisis we meet today are unlikely to be so extreme,but however little the stress,it involves the same response.All the energy is shifted to cope with the stress.It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress. Stress in some people produces stomach disorders,while others experience tension headaches.Since we cannot remove stress from our 1ires,We need to find ways to cope with it. Question: People are finding less and less time for relaxing themselves because _ . Yes or no, is the answer "they are suffering from the effects of stress"?
A: No

Q: Article: The next generation of smart phone could combine the date from its gyroscopes with a built-in compass to allow you to track your indoor movements even without GPS. Research described it in the international Journal of Innovative Computing and Applications by Shahid Ayub of Lancaster University, and his colleagues there and at HW Communications, suggests that the embedded inertial sensors in many smart phones have added the facility to be used for localization and tracking applications. The primary benefit of using smart phones is that no additional infrastructure would need to be installed for monitoring personnel movements in a wide variety of situations not least staff, equipment and inventory movements in warehouse facilities, shopping malls and factories. In contrast, other technology being proposed would require new equipment,such as RFID technologies. However, smart phones do not yet have the ability to pinpoint their location without recourse to the GPS system, which is not accessible indoors and has the added disadvantage of using up battery power very quickly even if it could be used. Inertial navigation only provides the necessary information to a specified starting point the team says. This is useful for anyone with a non-GPS smart phone who wishes to track the route they take when walking or jogging if they specify their starting point. The team suggests that pedestrians indoors could be positioned using a combination of the smart phone accelerometer and an built-in digital compass, something that will become available in future smart phones. They have now investigated the potential of three different smart phone placement modes: idle, hand held and listening, which could be used with pedestrian dead reckoning (PDR) techniques to allow users to record the path they follow or for various kinds of workplace or other monitoring requirements. "The technique could be used in underground tube stations, airports , train stations where there is no infrastructure installed for tracking or... Question: We can learn from the passage that the recent studies of smart phones _ . Yes or no, is the answer "can be applied to underground tube stations"?
A: Yes
