Part 3: For questions from 66 to 75, read an article about computers. Choose from the list (A-K) the sentence which best summarizes each part (66-75) of the articles. There is one extra sentence which you do not need to use. Write your answers in the Answer Sheets. (2.0 pts)
66. Machines which seem to think have become a regular feature of our lives. Tasks that 20 years ago would have been unthinkable are now simple for quite basic computers.
67. The most complex computers can boast remarkable achievements. Automatic pilots fly jumbo jets, and the most sophisticated airports such as Heathrow even the largest jets can now land in zero visibility, relying entirely on computers.
68. Chess is another field where the machine’s advances go far beyond mankind’s. The most advanced computers are now match for all but the very best players and it won’t be long before they will be capable of beating the champions.
69. But it is enough for us to describe these machines as intelligent, or are their achievements in reality just a success for the scientists who have programmed them to perform a series of tasks rapidly and efficiently?
70. Different people use the term “artificial intelligence” to mean different things. But before it can be argued successfully that we are in the presence of an artificial intelligence, we have to prove that a machine can- as a minimum- “learn” from the environment, independently of its programmer.
71. One important difference between computers and the human brain is that computers rely on “serial processing”. The fact that the computer may be able to win a complex game like chess simply reflects its ability to look at numerous possible series of moves at rapid speed and to “learn” not to make losing moves.
72. Quite apart from its ability to be influenced by the environment, the human brain differs from even the most advanced computer in that it operates with so-called “parallel processing”, doing several things at once.
73. Sir Clive Sinclair, one of the original computer experts, is convinced that parallel processing programs for computers will be with us soon, and that these will totally change society. With parallel processing, computers would be expected to “learn” better from their experiences and perhaps, be able to pass on the fruits of such learning to other computers, each in turn becoming more advanced. Thus could be born a generation of computers able to offer at least a more realistic attempt at intelligence.
