Read the following article and select the best answer. Article: A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants. Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules .It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles. The team calculates the Car-puccino will do three miles per kilo of ground coffee -- about 56 cups of espressos per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours. Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much. Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn't matter." He said the same technology could be used to power a car on other unusual... Question: What can be inferred from the passage? - All kinds of materials can be used as fuels. - The Car-puccino will be put into the market soon. - Nick Watson is the designer of the Car-puccino - Much remains to be improved for the Car-puccino.
Much remains to be improved for the Car-puccino.

Read the following article and select the best answer. Article: Never argue with one's own understanding. The whisper of intelligence is always there, whatever you do. If you create a time lag between the whisper of intelligence and understanding in you and your action, then you are preventing the brain from growing into a new size. When you argue with intelligence, when you postpone acting according to understanding then there is confusion, the brain gets confused. The voice of understanding, the voice of intelligence has insecurity about it. How do you know that it is the right thing? So we tend to ignore it. Instead we accept authority. We obey. But the brain cannot be orderly, competent, accurate and precise if you do not listen to it, if you have no respect. We are so busy with the outside world and its force that the world that is inside us does not command that respect and reverence , that care and concern from us. So one has to be a disciple of one's own understanding, and look upon that understanding as the master. Sometimes one may commit a mistake, it might be the whim of the ego and we might mistake the whim, the wish of the ego for the voice of silence and intelligence, but that we have to discover. Unless you commit mistakes, how do you learn to discriminate between the false and the true? In learning there is bound to be a little insecurity, a possibility of committing mistakes. Why should one be terribly afraid of committing mistakes? So instead of accepting the authority of habits and conditionings, while one is moving one watches, and when there is a suggestion, do not neglect, ignore, or insult the whisper from within and from one's own intelligence. Question: The best title of the passage might be _ . - Never argue with your own understanding - Never believe any authority while arguing - Never neglect whispers from around you - Never stop training yourself.
(Answer)
Never argue with your own understanding

Ques:Read the following article and select the best answer. Article: Heroes of Our Time A good heart Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship to study medicine--but Coach John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this goodhearted man: " Mutombo believes that God has given him this chance to do great things." Success and kindness After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children's videos in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others--producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: " I believe it's the most important thing that I have ever done. I believe that children have the right to live in a world that is safe." Bravery and courage A few weeks ago, Wesley Autrey was waiting at a Harlen subway station with his two little girls when he saw a man fall into the path of a train.

He says: " We have got to show each other some love." Question: Mutombo believes that building the new hospital is _ . - something he should do for his homeland - helpful to his personal development - a chance for his friends to share his money - a way of showing his respect to the NBA
