Ques: Read the following article and select the best answer. Article: Bicycles for rent could become as common as newspaper stands and mail boxes on prefix = st1 /Germany's street corners if a scheme launched by Deutsche Bahn is successful. The German rail operator has launched a bicycle-hire scheme designed for simple one-way trips. "It's a new concept,"said Andreas Knie, head of the project. Users must first register with Call-A-Bike at a cost of 15 euros(US$14.7). With a simple phone call, they can hire one of the many bikes parked outside stations, at a cost of 3 to 5 cents per minute. At the end of their journey, they ring a computer and tell it where the bike is parked. The bikes are available 24 hours a day, seven days a week. No one will be breaking speed records with Call-A-Bike bicycles. They weigh in at 25 kilograms, at least double the weight of a normal bicycle, though they do have eight gears . "They are pretty heavy, but we don't want people taking them on the train or into the subway," Knie said. They are also designed with parts that do not fit a normal bicycle. Even the screws are irregular and the bike looks so odd that thieves would stand out. Vandalism and theft have led to the downfall of previous schemes which date back toAmsterdam's 1966"White Bike"scheme. In that short-lived experiment, anti-establishment groups painted bikes white and left them around the Dutch capital. However, many were taken permanently and repainted, while the police took away others on the basis that ownerless bikes were street rubbish. Copenhagen, Vienna and Helsinki also have free bike schemes, in which users deposit a coin in Copenhagen's case 20 crowns(US$2.50)--to free a bike from a rack. "The advantage these schemes have is ease of use. But because they're so cheap, people tend to hold on to the bikes and then there are none on the streets,"the person in charge said. Oslo is also planning a bike-hire system where users will pay a symbolic fee of 50 Norwegian crowns(US$6.50)for unlimited use in the city for a year. Users will buy an electronic... Question: What can be learned about Amsterdam's 1966"White Bike"scheme? - The bicycles were twice as heavy as a normal bicycle. - A heavy rain stopped the scheme from being carried out. - Some bicycles were damaged or stolen and the scheme failed. - The police ended the scheme for traffic safety
Ans: Some bicycles were damaged or stolen and the scheme failed.

Ques: Read the following article and select the best answer. Article: Every foreign student who has been accepted to study in this country must have a legal document called a visa from the prefix = st1 /United Statesgovernment. A visa permits a foreign citizen to travel to theUnited Statesand request permission to enter the country. The rules for getting a visa can be found on the State Department Web site. The address is unitedstatesvisas. gov. Unitedstatesvisas is all one word. Another State Department Web site for students from other countries is educationusa. gov. If you are requesting a visa for the first time, you may have to appear at the American Embassy in your country to talk to an official. Each student should communicate with the Embassy to find out if such an interview is needed and when it can take place. It is important to apply for the visa early. State Department officials say national security is the most important issue in deciding if a person will be permitted to enter the United States. Officials must find out if a student is on any list of people with possible links to terrorists. Embassies can not issue a visa more than ninety days before the start of the educational program in the United States. If you are a student studying in theUnited Statesfor the first time, you will not be permitted to enter the country more than thirty days before the start of your classes. Foreign students accepted at an American school will receive a document called a Certificate of Eligibility. The State Department says each student must enter the country using the certificate provided by the school he or she will be attending. It is a violation of the law to enter the country on one school's certificate but attend another school. You are permitted to stay in the United Stateson a student visa for the length of your period of study. That means you can stay as long as you are a full-time student.
