The correct answer is Patient.
A college is an institution of higher learning where students go to study. A hospital is a place where people go to get medical treatment. The students in a college are analogous to the patients in a hospital. Both students and patients are seeking help from an expert (a teacher or a doctor) in order to improve their situation.
The other options are not as good matches for the analogy. A nurse is a person who works in a hospital and provides care for patients. A doctor is a person who is qualified to diagnose and treat illnesses. Treatment is the process
of providing medical care to a patient. While all of these things are related to hospitals, they are not as closely related as the relationship between students and patients.In conclusion, the correct answer to the question “College : Student :: Hospital : ?” is Patient.
