问题     For the past few months, artificial intelligence(AI)has been a much talked about topic in the worlds of both pop culture and science. Last November saw the release of Oscar-nominated and winning biopic, "The Imitation Game", about the father of the modern computer, Alan Turing. Last month, another Hollywood film about clever robots, Chappie, hit theaters.
    Is artificial intelligence a boon or does it spell doom for humans? In their book, authors Erik Brynjolfsson and Andrew McAfee, both of whom hail from MIT, US, could barely hide their excitement toward the rise of machines.
    According to the authors, we are entering an age of accelerated development of artificial and robotic technology. "Digital machines have escaped their narrow confines and started to demonstrate broad abilities in pattern recognition, complex communication, and other domains that used to be exclusively human," write the authors. "We’ve recently seen great progress in natural language processing, machine learning, computer vision, simultaneous localization and mapping, and many other areas.
    "We’re going to see artificial intelligence do more and more, and as this happens costs will go down, outcomes will improve, and our lives will get better." Already AI can help blind people see and deaf people hear. And wheelchairs have been invented that can be controlled by thoughts. We are going to witness more innovations and wonders made possible by AI, according to the authors.
    However, not all are equally enthusiastic about AI. A February report from the Global Challenges Foundation listed AI, alongside extreme climate change, nuclear war and ecological catastrophe, as "risks that threaten human civilization". Many preeminent scientists share the same concern. Stephen Hawking told the BBC last December that "the development of full artificial intelligence could spell the end of the human race." "It would take off on its own, and redesign itself at an ever increasing rate," he said: "Humans, who are limited by slow biological evolution, couldn’t compete, and would be replaced."
    Hawking’s worry echoed that of Tesla and SpaceX boss Elon Musk, who said in last October at an MIT conference that "we should be very careful about artificial intelligence. If I had to guess at what our biggest existential threat is, it’ s probably that".  
It cannot be inferred that artificial intelligence will______.

选项 A、complete more chores
B、help cut down costs
C、help deaf people hear
D、control people’ s thought

答案D

解析 根据题干定位到第四段。D项control people’s thought(控制人们的思想)与原文And wheelchairs have been invented that can be controlled by thoughts不符,原文是说轮椅可以通过思想来控制。A项complete more chores对应于原文do more and more.B项helpcut down costs对应于原文as this happens costs will go down,C项为原文再现。因此D项为正确答案。
