questionsdirections: each passage in this section if followed by a group of questions to be answered on the basis of what is stated or implied in the passage. for some questions, more than one of the choices could conceivably answer the question, however, you are to choose the best answer; that is, the response that most accurately and completely answers the question, and blacken the corresponding space on your answer sheet.the fairness of the judicial process depends on the objective presentation of facts to an impartial jury made up of ones peers. present the facts, and you have a fair

to transport jurors to the time and place of the disputed event, to recreate the disputed event, or at least to explain that event with maximum accuracy. a trial falls short of this goal, however.(15)because it presents selected witnesses who recite selected portions of their respective memories concerning selected observations of the disputed event. these multiple selections are referred to as the abstraction process.(20)limitations in both perception and memory are responsible for the fact that the remembered event contains only a fraction of the detail present during the actual event, and the delay between observation and(25)recitation causes witnesses memories to lose even more of the original perceptions. during the course of a trial, a witnesss recitation of the now-abstracted events may reflect selected disclosure based on his or her(30)attitudes and motivations surrounding that testimony. furthermore, the incidents reported are dependent on the lines of inquiry established by the attorneys involved. accordingly, the recited data are a(35)fraction of the remembered data, which are a fraction of the observed data, which are a fraction of the total data for the event. after the
