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 reason for Microsoft controlling personal computers is that______.
选项 A、it has formed a good platform
B、its software has gained a lot of money
C、its Windows software became popular among consumers
D、its software has been widely used in search bar
答案C
解析 根据题干关键词定位到第二段。根据Microsoft dominated personal computers because its Windows software became the center of the consumer software world．可知微软以前能统治个人电脑，是因为它的Windows软件成了消费类软件领域的核心。故C项为正确答案。A项“微软已经形成一个好的平台”和B项“微软的软件已经获利很多”是对前两句的过度推断。D项“微软的软件被广泛地应用于搜索领域”属于张冠李戴，原文是说谷歌的软件被广泛地应用于搜索领域。故排除。
