问题    Many of the tech industry’ s biggest companies, like Amazon, Google, IBM and Microsoft, are jockeying to become the leader for artificial intelligence(A.I.). In the industry’s term, the companies are engaged in a "platform war."
   A platform, in technology, is essentially a piece of software that other companies build on and that consumers cannot do without. Become the platform and huge profits will follow. Microsoft dominated personal computers because its Windows software became the center of the consumer software world. Google has come to dominate the Internet through its ubiquitous search bar. If true believers in A.I. are correct that this long-promised technology is ready for the mainstream, the company that controls A.I. could steer the tech industry for years to come. "Whoever wins this race will dominate the next stage of the information age," said Pedro Domingos, a machine learning specialist and the author of "The Master Algorithm," a 2015 book that contends that A.I. and big-data technology will remake the world.
   In this fight—no doubt in its early stages—the big tech companies are engaged in tit-for-tat publicity stunts, circling the same start-ups that could provide the technology pieces they are missing and, perhaps most important, trying to hire the same brains. Fei-Fei Li, a Stanford University professor who is an expert in computer vision, said one of her Ph.D. candidates had an offer for a job paying more than $1 million a year, and that was only one of four from big and small companies.
   For years, tech companies have used man-versus-machine competitions to show they are making progress on A.I. In 1997, an IBM computer beat the chess champion Garry Kasparov. Five years ago, IBM went even further when its Watson system won a three-day match on the television trivia show "Jeopardy!" Today, Watson is the centerpiece of IBM’s A.I. efforts.
   By 2020, the market for machine learning applications will reach $40 billion, IDC, a market research firm, estimates. And 60 percent of those applications, the firm predicts, will run on the platform software of four companies—Amazon, Google, IBM and Microsoft. Intelligent software applications will become commonplace, said Jeff Dean, a computer scientist who oversees Google’s A.I. development. "And machine learning will touch every industry."
Google can steer the tech industry in the future on premise that______.

选项 A、it has controlled the Internet
B、A.I. has prepared to be the mainstream
C、it has won in the information age
D、A.I. and big-data technology have become mature

答案B

解析 细节题。根据题干关键词定位到第二段。根据If true believers in A.I.are correct that this long-promised technology is ready for the mainstream,the company that controls A. I.could steer the tech industry for years to come.可知如果笃信人工智能的人是正确 的——这种早就被寄予厚望的技术即将成为主流,那么在未来的岁月里,掌握该技术的 谷歌可能会在科技行业占据主导地位。故B项为正确答案。做对此题的关键是正确理解 this long-promised technology指的是人工智能技术;联系上下文可知the company指的 是谷歌公司。A项“它控制了互联网”,C项“它在信息时代获得了胜利”和D项“人工智 能和大数据技术变成熟”均是对文章片段的断章取义,均不符合题意,故排除。
