A large company is preparing to hire a car driver with a high salary. After layers of screening and examinations, only three competitors with the best skills are left. The examiner asked them: "There is a nugget of gold on the edge of the cliff. If you drive to get it, how close do you think you can get to the cliff without falling?" "Two meters. " said the first person. "Half a meter." The second person said confidently. "I'll try to stay as far away from the cliff as possible," said a third. As a result, the company admitted the third person.
