Read the article and select the best answer. Article: It was New Year's Night. An aged man was standing at a window. He raised his mournful eyes towards the deep blue sky, where the stars were floating like white lilies on the surface of a clear calm lake. Then he cast them on the earth, where few more hopeless people than himself now moved towards their certain goal --- the tomb. He had already passed sixty of the stages leading to it, and he had brought from his journey nothing but errors and remorse. Now his health was poor, his mind vacant, his heart sorrowful, and his old age short of comforts. The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads --- one leading to a peaceful, sunny place, covered with flowers, fruits and filled with soft, sweet songs; the other leading to a deep, dark cave, which was endless, where poison flowed instead of water and where devils and poisonous snakes hissed and crawled. He looked towards the sky and cried painfully, "O youth, return! O my father, place me once more at the entrance to life, and I'll choose the better way!" But both his father and the days of his youth had passed away. He saw the lights flowing away in the darkness. These were the days of his wasted life; he saw a star fall down from the sky and disappeared, and this was the symbol of himself. His regret, which was like a sharp arrow, struck deeply into his heart. Then he remembered his friends in his childhood, who entered on life together with him. But they had made their way to success and were now honored and happy on this New Year's Night. The clock in the high church tower struck and the sound made him remember his parents' early love for him. They had taught him and prayed to God for his good. But he chose the wrong way. With shame and grief he dared no longer look towards that heaven where his father lived. His darkened eyes were full of tears, and with a despairing effort, he burst out a cry: "Come back, my early days! Come back!" And his youth did...

By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm. "Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people," said Chris Urmson, director of Google's self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google's headquarters in Mountain View, California. Previous testing has taken place only on closed courses. The cars are built to operate without a steering wheel, accelerator or brake pedal. "Our software and sensors do all the work," Urmson said. "The vehicles will be very basic -- we want to learn from them and adapt them as quickly as possible -- but they will take you where you want to go at the push of a button." The prototype are the first of a 100-car fleet the tech giant is building. In the long run, Urmson sees a future of safer roads -- the majority of auto accidents are caused by human error -- and fewer traffic jams. Robotic cars could also shuttle people who can't drive because of age or illness. Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls. The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow "safety drivers" to take control if needed. Google says... Question: The passage informs us that self-driving cars _ . Options: A: have already passed necessary tests B: have been purchased by some companies C: will be able to communicate with drivers D: will probably decrease traffic jams
