Counselor: Many people assume that personal conflicts are inevitable, but that assumption is just not so. Personal conflicts arise primarily because people are being irrational. For instance, people often find it easier to ascribe bad qualities to a person than good ones -- even when there is more evidence of the latter. If someone suspects that a friend is unreliable, for example, a single instance may turn this suspicion into a feeling of certainty, whereas a belief that someone is reliable is normally built up only after many years of personal interaction. Which one of the following most accurately expresses the main conclusion drawn in the argument? ['Personal conflicts are not inevitable.', "It is irrational to allow a single instance to turn one's suspicion that a friend is unreliable into a feeling of certainty.", 'Even when there is more evidence of good qualities than of bad ones, people find it easier to ascribe bad qualities than good ones.', 'Unlike a suspicion that a friend is unreliable, a belief that someone is reliable is normally built up only after many years of personal interaction.']
