32-35
London taxi drivers know the capital like the back of their hands. No matter how small or indistinct the street is, the driver will be able to get you there without any trouble. The reason London taxi drivers are so efficient is that they all have gone through a very tough training period to get special taxi driving license. During this period, which can take two to four years, the would-be taxi driver has to learn the most direct route to every single road and to every important building in London. To achieve this, most learners go around the city on small motor- bikes practicing how to move to and from different points of the city. Learner taxi drivers are tested several times during the training period by government officers. The exams are terrible experience. The officers ask you "How do you get from Birmingham palace to the Tower of London" and you have to take them there in the direct line. When you get to the tower, they won’t say "well done ’. They quickly move on to the next question. After five or six questions, they will just say "See you in two months’ time." and then you know the exam is over. Learner drivers are not al lowed to work and earn money as drivers. There fore, many of them keep their previous jobs until they have obtained the license. The training can cost quite a lot, because learners have to pay for their own expenses on the tests and the medical exam.
A. Because learners have to pay for their own expenses on the tests and the medical exam.
B. Because for some learners, the training cost is too expensive.
C. Because the training time is too long.
D. Because learners cannot get payment during the training period.
