[单选题]The development of the Semantic Web proceeds in steps, each step building a layer on top of another. The pragmatic justification for this approach is that it is easier to achieve （71）on small steps, whereas it is much harder to get everyone on board if too much is attempted. Usually there are several research groups moving in different directions; this （72） of ideas is a major driving force for scientific progress. However，from an engineering perspective there is a need to standardize. So, if most researchers agree on certain issues and disagree on others, it makes sense to fix the point of agreement. This way, even if the more ambitious research efforts should fai1， there wil1 be at least（73）positive outcomes.Once a （74）has been established ，many more groups and companies will adopt it，instead of waiting to see which of the alternative research lines will be successful in the end.

[不定项选择题]资料：For promotions to remain effective, RT company has to analyze the impact of different campaigns. Word of mouth promotions can be more difficult to measure than some traditional methods of promotion. Although healthy sales are an important measure, RT uses other measures to evaluate the effectiveness of its activities. For example: Setting targets for sales returns from the smaller promotional activities. Evaluating the amount of editorial coverage its activities receive in the media. Measuring the number of blogs related to RT's products and the frequency of comment on these blogs. Evaluating the online influence of RT activities in the social media. For example, on Twitter there are around 260000 followers of RT activities.On Facebook,more than 21000000 consumers like RT. Conducting an annual brand health-check with consumers to ensure that they like the brand. Measuring the outcomes of RT promotions is not just about return on investment. These figures do not create the whole picture. This is because it can be difficult to value word of mouth promotions on paper. Sales returns do not take not account other factors such as longer-term brand loyalty. What is the passage about?
A.the sales report of RT campaigns.
B.the sales report of RT company.
C.how Facebook and Twitter have influenced the market.
D.how to evaluate promotional activities.

[不定项选择题]共用题干 The Development of American Postal System
In the early days of the United States,postal charges were paid by the recipient and charges varied with the distance carried.In 1825,the United States Congress permitted local postmasters to give letters to mail carriers for home delivery,but these carriers received no government salary and their entire compensation depended on what they were paid by the recipients of individual let-ters.In 1847,the United States Post Office Department adopted the idea of a postage stamp, which of course simplified the payment for postal service but caused grumbling by those who did not like to prepay.Besides,the stamp covered only delivery to the post office and did not include carrying it to a private address.In Philadelphia,for example,with a population of 150,000,peo- ple still had to go to the post office to get their mail.The confusion and congestion of individual citizens looking for their letters was itseff enough to discourage use of the mail.It is no wonder that,during the years of these cumbersome arrangements,private letter-carrying and express bus-mnesses developed.Although their activities were only semi-legal,they thrived and actually adver-tised that between Boston and Philadelphia they were half-day speedier than the government mail. The government postal service lost volume to private competition and was not able to handle effi-ciently even the business it had.Finally,in 1863,Congress provided that the mail carriers who delivered the mail from the post offices to private addresses should receive a government salary, and that there should be no extra charge for that delivery. But this delivery service was at first confined to cities,and free home delivery became a sing of urbanization.In 1890,of the 75 mul-lion people in the United States,fewer than 20 million had mail delivered free to their doors.The rest,nearly three quarters of the population,still received no mail unless they went to their post office. Which of the following statements about free home delivery in the United States of the late 19th century is not true?
A.Mail carriers got paid by recipients.
B.Mail carriers got paid by government.
C.Most people still went to post office to get mails.
D.Only people living in big cities could have the service.
