Article: Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer than they should be. What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emission from cars and factories. It is widely agreed that oil and coal create greenhouse gases when they are burned to produce heat or power. These emissions include carbon dioxide, which is the cause of most of the global warming problem. The loss of the trees in many areas is making the problem worse, because trees and plants absorb carbon dioxide and release oxygen. The fewer trees that are left standing, the less carbon dioxide can be absorbed. Scientists predict that the sea level will rise, ice caps will melt, and some animals and plants will fail to survive because their habitat will disappear. There may be more deserts and less available farmland because of the dry ground, and there may be more storms and floods in many countries. Some countries, including the UK and the US, are taking steps to prevent the situation from becoming worse. There are programmes to educate citizens and students about the situation and recycling waste is becoming more common. New guidelines are being introduced to try to limit greenhouse gases from being produced by factories and businesses. Using more alternative energy sources is also a good way to prevent global warming. One thing that everyone can do is limit their use of energy every day, and you can do this no matter how old or young you are. Try to limit the unnecessary use of electricity and work to conserve energy every day.
Answer: No Emissions, No Warming

Article: Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
Answer: People know little about their personalities.

Article: The card using a built-in voice-recognition chip requires users to give a spoken password that it recognizes. The idea is to prevent thieves from using a stolen card to buy goods online. A model built by engineers in California packs a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card. The card is the length and width of an ordinary credit card but about three times as thick. The company now plans to make it thinner. The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals. The Beep card has no microphone, but has a built-in loudspeaker to utter an audible ID signal by a computer's microphone to an online server . By confirming that signal matches the information in the card, the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand. The ID code, which only the server knows, changes each time the card is used. This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later. But this earlier Beep card technology cannot prevent illegal use of stolen cards. The new voice card can. The new voice card doesn't identify itself by its ID until it has confirmed the real user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy. The challenge for Beep card has been to develop voice-recognition and audio circuitry . The voice-recognition credit is powered by a mini battery. To extend batter life, the electronics have only to be switched on when the card is being used. Pressing a button on the card's surface allows one to hear a female voice saying, "Say your password." If the voice-recognition software proves that the password is real, it sends its ID, which the server then identifies, allowing the deal to continue.
Answer: It makes fraud more difficult.
