Final answer:
The phrase 'His heart was not in it' points to a lack of passion or dedication in a medical student. This lack of commitment is further exemplified by students like Kim, who fails to take responsibility for his poor performance, and contrasts with Jarrett, who actively seeks help to improve.
Step-by-step explanation:
In describing an unsatisfactory medical student, the phrase that indicates a lack of passion or dedication is C. His heart was not in it. This phrase signifies that the individual is not emotionally or mentally invested in their education or pursuit of the medical profession. For example, in the case of a student named Kim, despite failing his history course due to not studying or attending class, he blamed the failure on the professor's personal dislike towards him. This demonstrates a lack of accountability and passion for his studies.
Another example can be seen where a student's eyes become dull and glazed from excessive copying in poor lighting conditions, which could suggest overworking without genuine engagement or enthusiasm for the content itself. On the contrary, a student named Jarrett demonstrates how dedication can lead to improvement when he sought help from the academic success center and changed his study habits, which ultimately helped him improve his grades.
It is crucial to recognize that student performance is generally influenced by a combination of attendance, innate ability, and work ethic. A student who lacks these elements may experience consequences such as getting bad grades or not graduating, which are indicative of a lack of passion and dedication to their education.
