问题       In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, the era of digital convergence goes better than yesterday’s celebrated "information superhighway".  Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each another. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media. The problems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable. Even once global standards are assured, however, a further obstacle lies in wait. The Internet is plagued by long, erratic response times because it is a pull technology, driven by patterns of user demands. Push technology, on the other hand, reverses the relation-ship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom. Besides the issue of consumer habits, infrastructure costs are set to be immense, and will have to be met by national states or the private sectors before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coerced through clever marketing to upgrade to newer phones with more features to reinforce their dependence. Whatever the outcome, it is obvious that technology will play an increasing part in our everyday lives. Beyond technology, digital convergence embraces the services, industrial practices and social behavior that form modern society. We have in our hands the technology to construct the most sophisticated machines ever built, but if they are unusable, simply because of their operating instructions, then recent lessons have taught us they will not survive. Whatever we design must be simple, reliable and useful. Perhaps this is where artificial intelligence will come in. [br] Which of the following statements is NOT true about the digital convergence?
选项 A、It combines various media such as television and Internet together.
B、If achieved, it will be better than the well-reputed "information superhighway".
C、The technology is difficult to achieve as it seems impossible to establish platforms.
D、It is simply a technology that will play an important role in our lives.
答案 D
解析 细节题。文中倒数第6行提到：“Beyond technology，digital convergence embraces the services，industrial practices and social behavior that form modern society.”意思是说， digital convergence不仅仅是种技术，它也包括现代社会的服务、工业和社会行为等方面。因此D选项不符合原文。
