24.Which of the following statements would best serve　as an introduction to the passage？

　　（A） The assumption that the knowledge incorpor-　ated in technological developments must be　derived from science ignores the many non-　scientific decisions made by technologists.

　　（B） Analytical thought is no longer a vital com-　ponent in the success of technological development.

　　（C） As knowledge of technology has increased， the　tendency has been to lose sight of the impor-　tant role played by scientific thought in　making decisions about form， arrangement，　and texture.

　　（D） A movement in engineering colleges toward　a technicians degree reflects a demand fo　　graduates who have the nonverbal reasoning　ability that was once common among engineers.

　　（E） A technologist thinking about a machine，　reasoning through the successive steps in a　dynamic process， can actually turn the　machine over mentally.

　　25.The author calls the predicament faced by the　Historic American Engineering Record “para-　doxical“ （lines 36-37） most probably because

　　（A） the publication needed drawings that its own　staff could not make

　　（B） architectural schools offered but did not require　engineering design courses for their students

　　（C） college students were qualified to make the　drawings while practicing engineers were not

　　（D） the drawings needed were so complicated that　even students in architectural schools had　difficulty making them.

　　（E） engineering students were not trained to make　the type of drawings needed to record the　development of their own discipline

　　26.According to the passage， random failures in automatic control systems are “not merely trivial　aberrations“ （lines53） because

　　（A） automatic control systems are designed by　engineers who have little practical experience　in the field

　　（B） the failures are characteristic of systems　designed by engineers relying too heavily on　concepts in mathematics

　　（C） the failures occur too often to be taken lightly

　　（D） designers of automatic control systems have too　little training in the analysis of mechanical　difficulties

　　（E） designers of automatic control systems need　more help from scientists who have a better　understanding of the analytical problems to be　solved before such systems can work efficiently

　　27.The author uses the example of the early models of　high-speed railroad cars primarily to

　　（A） weaken the argument that modern engineering　systems have major defects because of an　absence of design courses in engineering　curricula

　　（B） support the thesis that the number of errors in　modern engineering systems is likely to　increase

　　（C） illustrate the idea that courses in design are the　most effective means for reducing the cost of　designing engineering systems

　　（D） support the contention that a lack of attention to　the nonscientific aspects of design results in　poor conceptualization by engineers

　　（E） weaken the proposition that mathematics is a　necessary part of the study of design

　　28.IGNITE：

　　（A） amplify

　　（B） douse

　　（C） obscure

　　（D） blemish

　　（E） replicate

　　29.MUTATE：

　　（A） recede

　　（B） grow larger

　　（C） link together

　　（D） remain the same

　　（E） decrease in speed
