Final answer:
Jackie's ambition and impatience with slackers align with a Type A personality, characterized by a high level of drive and competitiveness. Conversely, Jane's belief that her bad grade is due to her professor's dislike rather than her own efforts indicates an external locus of control.
Step-by-step explanation:
Jackie is described as being very ambitious, aiming to graduate with a high GPA and having little patience for slackers. The personality type that best fits Jackie's characteristics is Type A. This is because Type A individuals are characterized as intensely driven, competitive, and often impatient with others who do not meet their standards, which matches Jackie's description. They may also display a sense of urgency about time, multitask, and get easily frustrated with delays or impediments to their progress. Comparatively, Type B personality traits involve being more relaxed and laid-back, qualities which do not align with Jackie's description.
As for the question about Jane believing her bad grade is due to her professor's dislike of her, the type of locus of control she exhibits would be an external locus of control. Individuals with an external locus of control believe that their successes or failures are the result of external factors beyond their control, such as luck or other people's actions. Jane's belief that her grade is determined by her professor's personal feelings rather than her own efforts reflects an external locus of control.
