Pearl is kind, cooperative, appreciative, and sympathetic. ruby is outgoing, talkative, fun-loving, and sociable. pearl probably scores high on the big five dimension of whereas ruby likely scores high on

Agreeableness; extraversion

Explanation:

The Big Five was born from studies on the Theory of Personality Traits, representing a conceptual and empirical advance in this area, as it described basic human dimensions in a consistent and replicable manner.

The Big Five model began to be structured in the early 1930s, when McDougall suggested analyzing personality from five independent factors called neuroticism, extroversion, openness to new experiences, kindness, and conscientiousness.

Based on this concept and the paragraph shown in the question, we can say that Pearl is kind, cooperative, appreciative and friendly, so she probably scores high on the five great dimensions of kindness. On the other hand, Ruby is outgoing, talkative, fun and sociable, so she probably scores high on the five major dimensions of extroversion.
