Q: 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 fuels, such as woodchips or nut shells, construction or agricultural waste.
Answer: It should be very dry.

A: Which is the right way to choose the coffee used as fuels to run the Car-puccino?

Q: Article: Seven tips to good table manners Whether it's a dinner at a friend's house or a business meeting over lunch, we judge people based on their table manners. But what can you do if your kids do not behave themselves at the dinner tables? The following are seven tips to set your children on the road to good table manners: *Look for the good. Instead of pointing out all the things your children do wrong, point out what they do right. Please say, for example, "I am so proud of you. It was wonderful the way you served yourself." *Don't turn dinner into an unpleasant "lecture time". That will turn kids off not only manners, but dinner, and you, too. *Check your own example. Don't show up for dinner in just your underwear unless you want your kids to do the same. *Don't always consider your kids lazy and dirty ones. Instead, point out the behavior in a tender way. For example: " It' s a good idea to unfold your napkin, so if food falls you won't dirty your clothes." *Teach your kids good manners in the form of a game. One night a week, try to have a formal dinner. Try dressing up, serve a special meal, and expect more formal manners. That will help improve their sense of manners. *Make kids understand part of the tradition. Invite guests over and let kids help serve them. This helps them indirectly learn about table manners. *Try dining out once in a while. Fast food restaurants aren't counted. Try a nice restaurant and let kids order their own food, pay the bill and give the tip.
Answer: Improve kids' sense of manners by having a formal dinner at times.

A: Which of the following should parents do to help their kids learn good table manners?

Q: Article: Experts estimate that one out of every five fish sold was caught illegally. It threatens food security and hurts the environment. Officials are using new observational technology to fight illegal fishing. "Thank you for taking the time to join us here in Harwell (UK) in the Operations Center to what we call 'Project Eyes on the Seas.'" says Tony Long, who leads the Ending Illegal Fishing program for Pew Charitable Trusts. The group created Project Eyes on the Seas. Large three-dimensional images of a globe can be seen on a video. "It looks different from what you might expect because this globe only shows you the boats that are coming into this system from a live automated information system or AIS." The screen shows 120,000 fishing boats have AIS. They are required to have the technology. But those who are fishing illegally often turn it off. The technology does not tell observers when that happens. Project Eyes on the Seas combines satellite information with secret government records on every ship's past activities. Mr. Long says that permits researchers to understand exactly where the fishing boats are operating. The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship. Tony Long says he would like to be able to provide port officials all over the world with clear lists. They would inform the officials about ships to inspect, ships to bar from entrance, and ships to permit entrance for trade activities. The Pacific island nation of Palau was an early user of the technology. Palau has one of the richest fishing areas in the world. Last year, it announced a plan to ban commercial fishing in a 630,000 square kilometer area. K.B. Sakuma is a special adviser to the president of Palau. He says Palau is trying to deal with a recent increase in illegal, unsupervised and unreported fishing. "And it's come to a head in the last year or two. From our southern island in the evening you can see on the horizon just dotted lights of these illegal fishermen that come into our waters, fill their ships with our fish, our resources, our food security..."
