[单选题]Artificial intelligence,or AI,is called artificial for a good reason.Facebook made that point last week by ending its attempt to rely heavily on software algorithms to select news items for its 2 billion users.It announced Jan.19 that the Facebook"community"will be asked to rank news outlets by their trustworthiness.This reader feedback will promote"high quality news that helps build a sense of common ground"in a world with"so much division,"said chief executive Mark Zuckerberg.The first surveys have started in the United States and will soon expand to other countries.The company plans to include the local news outlets of users in its surveys.Like many digital platforms that act as news providers,Facebook had great faith in a belief that programmed electrons in computer servers can discern qualities of thought such as trust,fairness,and honesty.Even in respected newsrooms,however,these traits of character require constant upkeep among journalists and feedback from paying customers.Good judgment on news relies on orders of consciousness beyond what a machine can do.Rather than move toward becoming a hands-on gatekeeper of news,Facebook now hopes its"diverse and representative"sampling of users can lead to a ranking of news outlets-and that would bring a measure of objectivity in its news feed.The company may be in the news business but it has chosen to outsource news credibility to the collective wisdom of individuals and their ability to distinguish truth from falsehood.By placing its trust in people as seekers of truth,Facebook could earn greater trust from its users.This is also a lesson for many companies,especially digital platforms or those in the media business.According to the latest survey of trust in institutions worldwide by Edelman communications firm,"media has become the least-trusted institution for the first time,"more so than other businesses or government.In particular,the US is"enduring an unprecedented crisis of trust"among many of its institutions,says Richard Edelman,president and CEO of Edelman."The root cause of this fall is the lack of objective facts and rational discourse,"he adds.Facebook's shift away from computer-driven news selection is a welcome step toward restoring trust in the overall business of news.This is not a new problem."Nothing can now be believed which is seen in a newspaper,"wrote Thomas Jefferson in 1807.Yet the Digital Age has forced the issue of trust for news providers.By inviting readers to participate in solving this problem,Facebook has itself set a new bar for earning trust.
In the last paragraph,Thomas Jefferson's words are cited to indicate
A.the poor quality of newspapers nowadays.
B.the long-standing trust issue in news businesses.
C.the problems arising from Facebook's shift.
D.the issue of trust in the Digital Age.

[单项选择]Use of the illegal drag named Ecstasy (MDMA) has increased alarmingly in Britain over the last few years, and in 1992 the British Medical Journal claimed that at least seven deaths and many severe adverse reactions have followed its use as a dance drug.14 deaths have so far been attributed to the drug in Britain although it is possible that other drugs contributed to some of those deaths. While it is true that all drugs by their very, nature change the way in which the body reacts to its environment and are therefore potentially dangerous, it is still unclear whether casual use of Ecstasy is as dangerous as authorities believe. What is certain is that the drug causes distinct changes to the body which, unless understood, may lead to fatal complications in certain circumstances. In almost all cases of MDMA related deaths in Britain, overheating of the body and inadequate replacement of fluids have been noted as the primary causes of death. Yet in the US, studies appear to implicate othe

B. is less dangerous than the authorities believe

D. none of the above
