Read the following article and select the best answer. Article: We often hear people say, "I have a good memory for things like that" or "I can remember names". But do you know memory is the single most important thing and it has played a very important part? For early men, there were dangerous all around them--bad weather, wild animals. The key to keep on living lay in man's ability to remember these dangers and the ways he had dealt with them in the past. In order for memories to be stored, the human brain became more complex. And as man learned how to deal with them, he became civilized . Surprisingly, scientists today understand little about memory and how it works. They have not yet found a way to open up the brain and observe its function without destroying it. Perhaps there are two types of memory: short-term and long-term. Short-term refers to those facts that stay with us for a few seconds to a few hours. For instance, when you stay at a hotel, you remember the room number and forget as soon as you leave. Long-term memory, on the other hand, means you remember things for a long period of time. If you spend your honeymoon in a particular hotel, it's likely that you'll remember your stay quite clearly. Scientists also believe that a short-term memory can become a long-term memory through consolidation . A lot of chemical and physical changes take place in the part of the brain. Although the human brain weighs three pounds, it contains 30 billion nerve cells acting like a computer. When those changes strengthen the links in certain nerve cells, a thought becomes part of the long-term memory. Question: So far the great discovery scientists have made about the function of brain is _ - the weight of brain - two types of memory - 30 billion nerve cells - chemical and physical changes
chemical and physical changes

Read the following article and select the best answer. 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: As far as the cost for digital convergence is concerned, _ . - the expenses for building the basic facilities are too immense to be met. - the infrastructure costs should be paid by national states and the private sector alone. - the cost for building a platform can be recovered by collecting service charges. - the high cost can be covered by effective marketing to attract more customers.
(Answer)
the cost for building a platform can be recovered by collecting service charges.
