问题     It is 3 A.M. everything on the university campus seems ghostlike in the quiet, misty darkness- everything except the computer center. Here, twenty students rumpled and blear-eyed, sit transfixed at their consoles(操作台), tapping away on the terminal keys. With eyes glued to the video screen, they tap on for hours. For the rest of the world, it might be the middle of the night, but here time does not exist. This is a world unto itself. These young computer "hackers" are pursuing a kind of compulsion, a drive so consuming it overshadows nearly every other part of their lives and forms the focal point of their existence. They are compulsive computer programmers. Some of these students have been at the console for thirty hours or more without a break for meals or sleep. Some have fall- en asleep on sofas and lounge chairs in the computer center, trying to catch a few winks but loathe to get too far away from their beloved machines.
    Most of these students don’t have to be at the computer center in the middle of the night. They arch’ t working on assignments. They are there because they want to be--they are irresistibly drawn there.
    And they are not alone. There are hackers at computer centers all across the country. In their extreme form, they focus on nothing else. They flunk out of school and lose contact with friends; they might have difficulty finding jobs, choosing instead to wander from one computer center to an- other.
    Computer science teachers are now more aware of the implications of this hacker phenomenon and are on the lookout for potential hackers and cases of computer addiction that are already severe. They know that the case of the hackers is not just the story of one person’ s relationship with a ma- chine. It is the story of a society’ s relationship to the so-called thinking machines, which are be- coming almost ubiquitous(无所不在的).
It can be reasonably inferred from the passage that ______.

选项 A、the "hacker" phenomenon exists only at university computer centers
B、university computer centers are open to almost everyone
C、university computer centers are expecting outstanding programmers out of the "hackers"
D、the "hacker" phenomenon is partly attributable to the efficiency of the computer centers

答案C

解析 从最后一段Computer science teachers are on the lookout for potential hackers可以判断选项C正确,on the lookout for寻找。
