问题 DATA STORAGE ON-LINE
We are all well aware of the rapid growth of online databases. This has affected all levels of data storage, from the grandest government archives to the largest corporations and educational institutions all the way down to personal journals and family financial records. On the one hand, this transformation of the way that data is stored offers tremendous environmental advantages: much more data can be stored in a much smaller physical space and yet is more-easily available to more people. There is no need to print pages and then physically store them. More and better-organized information is more easily available without storage problems. Have we reached some kind of "infotopia"? Perhaps, but there is a serious downside, and that is the problem of document security. Computer systems, which are mostly continuously connected to the Internet, are all too prone to being hacked. This can be done for criminal reasons or simply because of the satisfaction that hackers get from cracking apparently secure information systems. New opportunities for theft, espionage, blackmail, and political dirty tricks are already in existence.
Which of the following is NOT mentioned as a benefit of using the online storage system?
选项 A、It uses less space to store more information.
B、It proposes to be environmentally friendly.
C、It facilitates the accessing of information by a greater audience.
D、It completely eradicates the recycling problem.
答案D
解析 文中具体提到的有：占用的空间少(A)，对环境有利(B)，更多的人可以轻松获取信息(C)。文中没有提到的是(D)。
