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"?
Yes

Article: Hong Kong is one of the most densely populated cities in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation for its light pollution. A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard. The crowded city of 7 million residents , full or residential high-rises, towering office blocks and neon advertisements, has no laws to control outdoor lightning. The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai. "In Hong Kong , you can't go anywhere outdoor in the evening without your eyes being blinded by this really disturbing outdoor lightning," the light pollution survey's head Jason Pum told AFP. "The fact that we have all this light in the sky means energy is wasted," he said, adding that too much artificial lightning also affects nightly wildlife. Research has suggested that light pollution can cause a number of harmful health effects in humans, including sleeplessness and headaches and can also interrupt body clocks and hormones . The university survey, the result of five million measurements taken from points across the city, was released just days before the start of the annual Earth Hour event, organized by the World Wildlife Fund. People around the world will be encouraged to turn off the lights for an hour on Saturday night to raise awareness of climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour. "Anyway, we should do our best to reduce the amount of lightning and adjust it for the benefit of the environment." Question: .which of the following statements about too much lightning is NOT true? Yes or no, is the answer "It can make the sky and the city more beautiful."?
(Answer)
No

Ques: Article: What would you do if you were lost in the dark forest at night? The first sensible lesson is that you shouldn't bother trying to find your way in the dark at all, but just stay put until dawn. Because then you won't trip over things? No, mainly because you'll have an idea of direction. The sun rises in the east. But you will be amazed at how many people forget they know that. Apparently, the area underneath a holly bush provides a good makeshift shelter -- they are thick, and evergreen. The next thing to do -- or rather not to do -- is panic, for the obvious reason that unless there is someone there to hear you scream, it will get you nowhere. Just try to think of nice, happy things. There is always a point in films when a person who is lost in the desert or the snow, dehydrated and exhausted, comes across a set of their own footprints and realizes they have just walked in a huge, round circle. It is wrong to owe it to the unequal strengths or different lengths of your legs. Experiments prove that, without the sun or the moon (or landmarks) as a fixed guide, lots of small errors add up over time so the brain can't correctly identify the "straight ahead" direction. To just get out of somewhere, pick a spot on the horizon and just head for it. There are several ways to find directions in the dark, and by far the best is to establish north using the stars. Most people can identify the Plough, which is part of Ursa Major. It looks a lot like a saucepan. The Plough rotates through the sky, but let's imagine the saucepan lying horizontally , with its handle on the left. You need to trace a line from the star at the right-hand base of the pan, through the star at the right-hand rim , and follow it upwards; the north star is roughly five times the distance between those two "pointer" stars. Then drop a vertical line from the North Star to the horizon and that's north. "Tonight is very cloudy and I can't see the Plough." Maybe luckily, it is quite windy. Keep in mind that almost all of our weather comes from a... Question: What might be the best title of the passage ? Yes or no, is the answer "How to direct your way out of the wild"?
Ans: No
