Explanation:

The Five-Factor Model of personality is a model of the structure of personality according to which human personality can be described using five broad dimensions: Extroversion, Agreeableness, Conscientiousness, Neuroticism, and Openness.

The main characteristics of the dimensions are:

Extroversion: Outgoing, socially confident behavior. Extroverts are sociable, talkative and enjoy being the center of attention. Introverts are more quiet and prefer to be on their own.Agreeableness: Individuals who score highly on agreeableness are friendly and co-operative, they are trusting of others and are more altruistic and sympathetic. People who score low on this dimension are less concerned with pleasing other people or making friends, they tend to be more suspicious and are less charitable.Conscientiousness: People who are conscientious are more aware of their actions and the consequences of their behavior than people who are unconscientious. They feel a sense of responsibility towards other people and are careful with their duties.  People who score low on this dimension are less careful and are less concerned about tidiness and punctuality.Neuroticism: People with high neuroticism are persistent worriers. They are fearful and often feel anxious, over-thinking their problems focusing on the negative aspects of them. They tend to become frustrated and angry if things don't go as they wish.  People who score low are less preoccupied and are able to remain more calm under stressful situations.Openness: Willingness to try new activities. People with higher levels of openness enjoy artistic and cultural experiences and are more open to unfamiliar cultures and customs.  People with low levels of openness are wary of uncertainty and the unknown and feel uncomfortable in unfamiliar situations and prefer familiar environments.

In this example, Pearl is kind, cooperative, appreciative and sympathetic; these are characteristics of people who have high scores in the dimension of agreeableness. On the other hand, Ruby is outgoing, talkative, fun-loving and sociable; these are characteristics of people high on extraversion.

Thus, Pearl probably scores high on the Big Five dimension of agreeableness whereas Ruby likely scores high on extraversion.
