Passage 3

The advent of computers has brought with it a new set of opportunities for mischief (危害) and crime. Today, computers are easy to come by and many people know how computer technology works. More importantly, the growing use of computer networks can multiply a breach (破坏) of security, making larger numbers of people more vulnerable(脆弱的) than would be the case if they were using single, stand-alone computers.

What’s more, computer experts agree that despite recent widespread publicity-computer viruses(病毒) are only one of many computer security problems facing the nation.

The U.S. Defense Advanced Research Project Agency has requested that the Research Council’s(委员会) Computer Science and Technology Board assess(评定) the security problems posed by computer technology, see what solutions may already exist, review research efforts aimed at avoiding security problem in the future, and evaluate existing policies relevant to computer security. The study committee will examine the issue of security for a broad spectrum of users, including the business, national security, and academic communities, as well as the general public.

David D.Clark, senior research scientist, Laboratory for Computer Science, Massachusetts Institute of Technology, will chair the committee of experts in electronic security, net work security, computer law, software engineering, cryptography(密码编制), and operating systems. The committee will also include computer users from the defense and banking industries.

阅读下面的短文，然后把划线的句子翻译成汉语。

(71)[The Internet is a powerful and cost-effective tool for conducting market research regarding consumer behavior, identifying new markets, and testing consumer interest in new products.] Although telephone or shopping mall surveys(调查) will continue, interest in interactive Internet research methods is on the rise. (72)[Online market research utilizing the Internet is frequently more efficient, faster, and cheaper, and you have the ability to get a more geographically diverse(不同的) audience than those found in offline surveys.] Furthermore, the size of a market research sample is the key determinant of research design. (73)[The larger the sample size, the larger the accuracy and the predictive capabilities of the results.] On the Web, one can conduct a very large research study much cheaper than with other methods (20 percent to 80 percent less). For example, (74)[telephone surveys can cost as much as $50 dollars per respondent.] This may be too expensive for a small company that needs several hundred respondents. An online survey will cost a fraction of this.

Internet-based market research is often done in an interactive manner by allowing personal contacts with customers, and it provides marketing organizations with greater ability to understand the customer, market, and the competition. For example, it can identify early shifts in products and customer trends, enabling marketers to identify products and marketing opportunities and to develop those products that customers really want to buy. (75)[It also tells management when a product or a service is no longer popular.]
