Read the article and select the best answer. Article: Hybrid cars are cars that run on petrol and electricity. They have a small standard petrol engine and a battery electric motor to provide electric power. There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example, when going uphill or accelerating. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic light, keeping only the electric engine running. Conventional cars have large engines to deal with driving uphill and accelerating. Hybrid cars have much smaller petrol engines, improved by electric motors when needed, so they use less petrol. Another way that fuel consumption is cut is by a system of "regenerative braking". The electric motor is used to slow down the car, rather than conventional brakes. The energy produced by slowing the car is changed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In conventional cars the energy produced when braking is wasted. In 1928 Ferdinand Porsche built an experimental hybrid car. The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997. However, hybrid cars became available in the USA only in 1999. As they use less fuel, hybrid cars are cheaper to run. There are also many voices in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don't have to pay on certain roads. In some cities, hybrid cars are allowed to park for free. Question: Hybrid cars consume less energy than conventional cars because hybrid cars _ . Options: A: have large engines to deal with accelerating B: have conventional brakes to slow down the car C: have electric power to assist when needed D: have no energy consumption when stopping

Question: Read the article and select the best 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." Question: The topic of the meeting in Seoul might be _ . Options: A: climate change B: global warming C: London Olympics in 2012 D: green environment
