Last week，German technology supplier Siemens AG said that it was close to signing a deal that would allow the world's only maglev train in commercial use.

　　In March last year，the central government approved a feasibility study on the 175 km Shanghai­Hangzhou route with speeds of up to 450 km per hour.But recent accidents and cost concerns，as well as strong opposition from local residents，have thrown a spanner in the works.

　　The project was expected to be completed by 2010 in time for the Shanghai Expo.

　　A maglev train on a trial run crashed in Germany last year，killing 23 people.In August last year，one of the maglev trains in Shanghai caught fire，forcing it to be evacuated.

　　Although the original budget was for ￥4.5 billion，Xinhua cited experts estimating a final tally exceeding ￥5.2 billion.

　　According to residents along the proposed route，the maglev line would have been separated from communities by a greenbelt only 22.5 meters wide，although a blueprint at the local government indicated a protection belt 150 meters wide would be built on either side.German specifications require a 300­meter leeway on both sides of the track.

　　5．The maglev rail route has been suspended mainly because of________.

　　A．recent accidents

　　B．concerns of radiation

　　C．cost concerns

　　D．disapproval from the government
