I'm taking a test and have to guess the right answer to the question after the article. Article: 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 other. 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 relationship: 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, infrastructurecosts are set to be immense, and will have to be met by national states or the private sector 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 coercedthrough clever marketing to upgrade to newer phones with more... Question: What is pull technology? Options: A: It is the Internet system affected by long, uncertain response times. B: It is the way of business operation driven by user demands. C: It is the technology to send information to passive users. D: It is a way to blend one-way television with interactive Internet.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels--petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be? Energy from the wind All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy. Energy from water When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive. Energy from the earth There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world. Energy from the sun Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy. Question: What can be inferred from the passage? Options: A: In order to protect our environment, we should try other kinds of energy. B: All scientists in the world will unite to find energy. C: People in modern life use energy every day. D: Energy changes people's lives.
Ans: A
