Question: 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? Yes or no, is the answer "It is the way of business operation driven by user demands."?
Answer: Yes

Question: Article: Scientists who try to predict earthquakes have gotten some new helpers recently--animals. That's right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives. One task for scientists today is to learn exactly which types of animal behavior predict quakes. It's not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It's also difficult at times to tell the difference between normal animal restlessness and "earthquake nerves". A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach. A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes. A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began... Question: During an earthquake in China in 1975, _ . Yes or no, is the answer "snakes awoke from their winter sleep earlier"?
Answer: No

Question: Article: If you put a buzzard in a pen six to eight feet square and entirely open at the top, the bird, in spite of its ability to fly, will be a prisoner. The reason is that a buzzard always begins a flight from the ground with a run of ten to twelve feet. Without space to run, it will not even attempt to fly, but remain a prisoner for life in a small prison with no top. The ordinary bat that flies around at night, a remarkably nimble creature in the air, cannot take off from a level place. If it is placed on the floor or flat ground, all it can do is to _ about helplessly and, no doubt, painfully,until it reaches some slight height from which it can throw itself into the air. Then, at once, it takes off like a flash. A bumblebee , if dropped into an open tumbler , will be there until it dies, unless it is taken out. It never sees the means of escape at the top, but insists on trying to find some way out through the sides near the bottom. It will seek a way where none exists until it completely destroys itself. In many ways, there are lots of people like the buzzard, the bat and the bumblebee. They are struggling about with all their problems and frustrations, not realizing that the answer is right there above them. Question: A bumblebee will completely destroy itself for _ . Yes or no, is the answer "it does not look for a way out above"?
Answer:
No
