input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Mayor Boris Johnson Monday outlined plans to make London "the cleanest, greenest city on Earth" by the 2012 Olympics and called for commitments from other world cities at a climate change conference, leaders of the world' s 40 largest cities are meeting in Seoul this week for a summit on combating global warming -- the third to be held since 2005. "What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine ," said Johnson. He said at a press conference the world's cities consume 75 percent of the world's energy and produce 80 percent of the emissions which cause climate change. "The problem of our planet is an urban problem," Johnson said. He said the British capital wants to use the Olympics "to drive the greening and the improvement of our city" and noted that London is committed to reduce carbon dioxide emissions by 60 percent by 2025. Johnson said the key measure was being taken to solve problems relating to housing and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting -- installing lagging -- in large numbers of public buildings. Johnson proclaimed himself a "passionate cyclist" and said he would push ahead with cycle superhighways around London. London's air quality problem, he said, was caused by vehicle emissions from 8,300 worn and used diesel buses, which could be replaced by low-carbon vehicles. In addition, there were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles. Johnson said there would be a few programs in the next few years to produce a "cleaner, greener" bus for the city. "The age of the diesel bus has got to be over in London." Options: A London's air quality will be improved in the near future. B The used buses running on diesel will be replaced by electric vehicles. C London promises to reduce carbon dioxide emissions by 60 pendent by 2025. D Something has been done to solve the problem of carbon dioxide emissions. Answer: B The used buses running on diesel will be replaced by electric vehicles. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available... Options: A fixed silicon between the graphene sheets B created tiny holes in the graphene sheets C made the graphene sheets in special shapes D used a special chemical process to make more efficient graphene sheets Answer: B created tiny holes in the graphene sheets Question:

Answer: To solve "traffic jam" while the battery charges, Kung's team _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: To: manager@ tastytreat.com.ca Date: Monday, 7 October, 3:34p.m. From: raymondyuen@ canada.net Subject: Complaint Dear Mr. Price, I have eaten in your restaurant many times and have always been happy with the food and service. This makes what happened last Saturday even more disappointing. It was my son's birthday so we booked a no-smoking table at your restaurant for 7:30 p.m. We arrived on time but were told that our table was not yet ready. At 8:00 p.m., we were given a table in the smoking section. I asked to move but I was told that there were no other tables. A lot of people were smoking so it was uncomfortable and unhealthy. Our first waitress, Janet, was very polite and helpful. She gave us free drinks for waiting so long. Our food also came quickly and looked fresh and tasty. When my wife had eaten most of her meal, she found a dead cockroach in her vegetables. She was shocked and wanted to leave. At first, the waitress told us it was a piece of garlic . When we told her that garlic does not have legs, she apologized and took the food away. We asked for the bill, expecting not to pay for my wife's meal. Nobody came. After 15 minutes, I asked to see the manager. The head waiter told us that you were on holiday. I complained again about the horrible cockroach. He told me Janet had finished work. He didn't believe my story and gave me a bill for three meals. I argued with him but was forced to pay. The waitress, Janet, was always friendly, but I would like an apology from your impolite head waiter and a full refund for our meal. It cost $68. Until then, I will not be eating at your restaurant or recommending it to anyone. You can contact me at 742-3254 or through e-mail if you want more information. Thank you for your attention. Yours sincerely, Raymond Yuen Options: A Mr.Yuen demanded that the head waiter apologize to him. B Mr.Yuen asked for a full refund for their meal. C Mr.Yuen will not eat at the restaurant any more. D The head waiter was not as polite as Janet. Answer: C Mr.Yuen will not eat at the restaurant any more. Question:???
