Final answer:
The teacher's observations about Kate's behavior are an example of the goal of psychology to describe behavior, which is the first step before explaining, predicting, or controlling behavior.
Step-by-step explanation:
The teacher's observations of Kate's behavior in class, such as being late, not turning in homework, squirming, and swinging feet, are examples of the goal of psychology to describe behavior. This descriptive information is a critical first step before a psychologist can move on to explaining, predicting, or controlling behavior. By describing what Kate is doing, the teacher provides the groundwork for a psychologist to later determine the causes and potential interventions for such behaviors.
