input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: People in cities all over the world shop in supermarkets. When you enter the supermarket, you see shelves full of food. You walk in the aisles, pushing your shopping cart. You probably hear soft, slow music in the supermarket. This kind of music is playing to relax you and make you walk slowly. Thus, you will probably stay longer and buy more food. Where do you go in the supermarket when you first arrive? Many people go to the meat section first. This area of the store has many different kinds of meat. Some kinds are expensive and others are not. Usually, some kinds of meat are on sale. So it has a special low price. The manager of the store knows where the customers usually enter the meat section. The meat on sale is usually at the other end of the section, away from where the customers enter. If you want to buy this specially priced meat, you have to walk by the more expensive meat first. Maybe you will see something that you want to buy before you reach the cheaper, inexpensive meat. Then you will spend more money in the meat section. The diary section sells milk that is low in fat. Some supermarkets sell three different containers of low-fat milk. Each container looks different, but each contains the same product. One says "1% fat", one says "99% fat free" and one says "low-fat" in big letters and "1%"in very small letters. If you look carefully you can see that all the milk has the same amount of fat, and each container is the same size. The prices of all these three should be the same. However, in many stores these three containers of milk would each have a different price. The store will make more money if a customer chooses the milk that costs the most. Most of the food in supermarkets is very attractive. People often stop to look at the products in attractive containers. But remember, many products will say, "Buy me!". Stop and think which ones are the best value for your money.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and 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... Options: A About 70 kilos B About 42 kilos. C About 32 kilos D About 30 kilos Answer: B About 42 kilos. Question:
