Questions 31 to 35 are based on the following passage. There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science. Another distinction between science and technology has to do with the progress in each. Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people’s likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people—as did Darwin’s theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hear the sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of living in a non-atomic age. Unlike science progress in technology must be measured in terms of the human factor. Technology must be our slave and not the reverse. The legitimate purpose of technology is to serve people in general, not merely some people, and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world. The difference between science and technology lies in that_______.
