Read the following passage and answer the questions.Passage 1For most people learning to drive, the driving test arises ahead as a major barrier. It is also a general source of conversation whenever drivers are gathered together. There are probably more tall stories about the driving test than about any other motoring subjects; the most remarkable thing about those stories is the number of times the old ones appear again, years after they were first heard, in new and exaggerated forms. All driving examiners have had to pass a very strict selection process, followed by at least six weeks’training. In the course of this training the Department makes sure that their driving is of a consistently high standard.Driving test centers are chosen with equal care.

Routes are carefully chosen to make sure that they are all roughly comparable—the proportion of right and left turns, hills, pedestrian (行人) crossings and so on. The object of all this is to make sure, as far as possible, that all candidates in the driving test have to cope with the same sort of conditions whether they take the test in New York or California.The work that examiners do in actually carrying out tests is checked continuously by supervising examiners.
