Exercise : Read the passage and choose the correct answer to each question. Who are the best drivers? Which drivers are the safest on the roads? According to a recent survey, young and inexperienced drivers are the most likely to have an accident. Older drivers are more careful. Young men have the worst accident records of all. They often choose faster cars with bigger engines. One of the most interesting facts in the survey is that passengers have an effect on the driver. When young male drivers have their friends in the car, their driving becomes worse. When their wife or girlfriend is in the car, however, their driving is better. But this is not true for women. Their driving is more dangerous when their husband or boyfriend is in the car. However, if their small children are riding in the car, they drive more slowly and safely. 1.
