Answer:
internal
Step-by-step explanation:
Research shows that people with a predominance of loci of internal control tend to be physically and mentally healthier. They believe they have greater freedom of choice, are more sociable and have a high degree of self-esteem, and believe that they can control every point of their lives.
We can say that Evelyn is a person with a predominance of loci of internal control, because when she learned that she had a chronic disease, she was not sad and depressed, but acted quietly, maintaining her self-esteem and sought to know more about the disease and to be able to control this point in her life.
