题目

阅读下列短文。从每题所给的A、B、C、D四个选项中选出最佳选项。 In the not-too-distant future, driverless cars will drive our streets. These cars will need to make quick decisions to avoid endangering human lives-both inside and outside of the cars. To determine attitudes toward these decisions, a group of researchers created a modem version of the classic exercise known as" the Trolley problem". They raised a series of moral dilemmas(道德困境)involving as elf-driving car with brakes(刹车) that suddenly give out Should the car change direction to avoid a group of passers-by, killing the driver? Or should it kill the people on foot but spare the driver? Does it matter if the passers by are men or women? Children or older people? Doctors or murderers? To put these questions to a large range of people, the researchers built a website called Moral Machine, where anyone could click through the situations and say what the car should do" Help us learn how to make machines moral," a video asks on the site. What the researchers found was a series of near universal preferences, no matter where someone was from. People everywhere believed the moral thing for the car to do was to spare the young over the old, spare humans over animals, and spare the lives of many over the few. The in findings were published Wednesday in the journal. Researchers found that the 130 countries with more than 100respondents(调查对象) could be grouped into three groups that showed similar moral preferences. And these preference seemed to be connected with social differences. Respondents from collectivistic cultures, which" value the respect for older members of the community," showed a weaker preference for sparing younger people. The researchers noted that the study's results should be used with extreme carefulness. and they shouldn't be considered the final word on societal preferences-especially since these respondents were much fewer than they had expected. （1） What give(s) rise to the questions in paragraph 2?
