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."
The tech companies show their progress by using
选项 A、competitions between men and machines.
B、chess games.
C、TV shows.
D、the profitability of new products.
答案A
解析 根据题干关键词定位到第四段。根据For years，tech companies have used man-ver sus-machine competitions to show they are making progress on A．I．可知多年来，科技企业一直 在用人机对战的方式来展示它们在人工智能领域取得的进展。故A项为正确答案。B项 “象棋"和C项“电视节目”均是文中用来说明A项的具体实例，故不全面。D项“新产品的 盈利能力”文中没有提及，属于无中生有，故排除。
