问题     In the weeks since IBM’ s computer, Watson, defeated two flesh-and-blood champions in the quiz show "Jeopardy!" , human intelligence has been punching back. Watson doesn’t "know" anything, experts say. It doesn’t laugh at jokes, cannot carry on a conversation, has no sense of self, and commits embarrassing mistakes no human would consider. What’ s more, it’ s horribly inefficient, requiring a roomful of computers to match what we carry between our ears. And it probably would not have won without its inhuman speed on the buzzer.
    This is all enough to make you feel energetic to be human. But focusing on Watson’ s short-comings misses the point. It risks distracting people from the transformation that Watson all but announced on its "Jeopardy!" debut: These question-answering machines will soon be working alongside us in offices and laboratories. Watson is an early sighting of a highly disturbing force.
    The key is to regard these computers not as human wannabes but rather as powerful tools, ones that can handle jobs currently held by people. The "intelligence" of the tools matters little. What counts is the information they deliver.
    In our history of making tools, we have long adjusted to the disturbances they cause. Imagine an Italian town in the 17th century, a man who has a special sense for the weather, called Luigi. Using his magnificent brain, he picks up on signals—changes in the wind, certain odors, perhaps the flight paths of birds or noises coming from the barn. And he spreads word through the town that rain will be coming in two days, or that a cold front might freeze the crops. Luigi is a valuable member of society.
    Along comes a traveling salesman who carries a new instrument invented in 1643 by Evange-lista Torricelli. It’ s a barometer, and it predicts the weather about as well as Luigi. It’ s certainly not as smart as him, if it can be called smart at all. It has no sense of self, is deaf to the animals in the barn, blind to the flight patterns of birds. Yet it comes up with valuable information.
    In a world with barometers, Luigi and similar weather experts must find other work for their fabulous minds. Perhaps using the new tool, they can deepen their analysis of weather patterns, keep careful records and then draw conclusions about optimal farming techniques. Maybe some of them drop out of the weather business altogether. The new tool creates both displacement and economic opportunity. It forces people to reconsider how they use their heads.
According to the text, Luigi differs from a barometer in that he
选项 A、predicts the weather better.
B、depends solely on his brain.
C、provides more valuable information.
D、earns more fame for his ability.
答案B
解析 该题为推理题。题干询问路易吉和气压计的区别是什么?仔细阅读短文的第四和第五段不难发现，路易吉的预测全靠自己的大脑，文中并没有就预测天气的准确性，价值信息的有效性和二者的名声进行比较。故选B。
