Speakers of a language rely on their general knowledge of the world in order to make sense of statements they hear or read. Computers can easily be "taught" the formal rules of a human language, but supplying them with this general knowledge is another matter. It is extremely difficult to develop computers that can extract the meaning of ordinary sentences.
Which of the following can be validly inferred from the passage above?
(A) The interpretation of the meaning of ordinary sentences is dependent on a general knowledge of the world. Correct
(B) Computers that can be "taught;' the rules of a human language can understand statements in that language.: Already mentioned in the argument so it cannot be the inference. Inference is something which is not mentioned but correctly interpreted.
(C) It is futile to try to "teach" computers the formal rules of any language.: Too strong. Also it is mentioned computers can easily be taught the rules of human language.
(D) Speakers of a language often must reject the formal rules of that language in order to understand simple sentences.: Too strong to reject. It is not the rules but additional general knowledge.
(E) Computers that can understand ordinary sentences have all the basic capabilities necessary to become "speakers" of the language.: " All basic capabilities" What are they? Cannot be inferred.
