Like airplane accidents, most accidents in medical care result from human error, particularly failures in communication, leadership, and decision making. Following the introduction of standard procedures governing these three areas, the airline industry succeeded in significantly reducing the number and severity of accidents. Since airplane flights and health care delivery both require the cooperation of groups of people with diverse knowledge and skills, the medical care community should adopt a similar set of procedures in order to reduce errors. Which one of the following is a technique of reasoning used in the argument? ['providing examples in order to show that two seemingly dissimilar situations are in fact the same', 'defending a general principle by presenting two separate successful applications of that principle', 'arguing for taking a course of action based on results of taking such action in an analogous situation', 'justifying the introduction of a set of procedures by outlining undesirable results in an analogous situation in which those procedures were not followed']
