Passage Two Questions 66 to 70 are based on the following passage: If an agreement signed in Germany works out, travelers of this Asian city may one day be able to move from the downtown area to its new airport on a train riding a stream of magnetic energy at speeds up to 500 kilometers per hour. The 40-kilometer trip----now sometimes a long hour journey when the traffic is heavy----could be cut to less than 10 minutes. Such are the goals of a costly project designed to help to “shorten” the distance between the city center and the sub busy airport by it easier and faster to carry travelers to and back from the airport. The mayor of the city and Germany’s Thyssen Krupp AG worked out an agreement in Berlin only several days ago that lays the groundwork for the magnetic levitation(悬浮) train line. They signed an agreement to carry out an initial study on the project and outlined the city’s intention to import German technology. The project, once completed and acceptable to the two business parties, will be a double-win: the German company can benefit from exporting its technology and the city receiving German technology can improve its traffic and further strengthen its position as an international city. Called Maglev for short, the system under discussion makes use of a high-speed train levitated above a guideway(高速车辆的导路) and driven by magnetic fields. The project has been in the talking stage for several months. Hans Ueberschaer, the German government official, visited the city together with Harmut Heine, representative of Thyssem Krupp. They had an initial discussion with the mayor three about the project. The talks were believed to be constructive and paved the way for the future talks in Berlin, where an agreement was reached. What is the main idea of the last paragraph
