Read the passage carefully and choose the best answer to each question out of the four alternatives.
A pioneering scheme has been started recently in Southampton on England's south coast to educate motorists who have been convicted of drunk driving. The penalty for drunk driving might be the loss of a driving license and a heavy fine. But under the new scheme, convicted drivers do not pay the fine. Instead they have to attend eight training sessions—one a week organized by the local authority probation service. Designed to demonstrate the damage alcohol can do, the scheme was devised by Senior probation officer John Cook. He said about a quarter of the people who came to him, had a drink problem, but had not realized how much they were drinking.
One way of getting the message across was to make the drivers pour out their usual ration of alcohol and then measure it. Almost everyone pours out not a single measure but a double at least an example of how easy it is to have more than just one drink and to encourage other people to do the same.
The instructors on the course are giving clinical evidence of the effects of alcohol on the body and brain. The sober truth is that drinking badly affects driving skills, although the drinker might like to believe otherwise.
