I'm taking a test and have to guess the right answer to the question after the article. Article: A city without cars would be very strange , right ? But Venice is such a city . Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city. Even so, travel isn't that difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat. Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences . One moment they walk across the Rialto Bridge , and there's nothing special . But when they come back to the bridge an hour later , it's underwater and everyone is wearing rain shoes . Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made ice of the Arctic Ocean   melt  . Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater. Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project , which was planned to be built under the seawater to stop the rising water . Anyway , this project is helping solve the problem . Question: Venice has gone down by 23 centimeters because   _   . Options: A: people used too much underground water B: it got higher little by little C: the temperature has fallen over the years D: more than half of the city is underwater

I'm taking a test and have to guess the right answer to the question after the article. Article: Recently,a solar powered plane took to the sky for the first time. It had passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland at 45km an hour. It slowly rose above the fields and into the sky. "There has never been an airplane of that kind that could fly -- never an airplane so big, so light, using so little energy," said Bertrand Piccard, a leader of the project. During the 90-minute flight, the plane did several turns. It climbed nearly 1.6km above the countryside. Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012. The plane flies at 70 km an hour. That is faster than a bike and slower than a car. Piccard and pilot Andre Borschberg will take the plane around the world. The pilots will keep the plane in the air for up to five days at a time. "We want to fly it day and night with no fuel  ," Piccard said Question: How long did the first flight of the solar powered plane last? Options: A: 45 minutes B: 60 minutes C: 70 minutes D: 90 minutes
