Answer to Question 1

ANS: C
When a study looks at individuals with a particular condition in comparison with those who do not have the disease, based on their exposures to various life situations, it is a retrospective study; that is, the study requires participants to look back at previous experiences. A cross-sectional study examines relationships between potential causal factors and disease at a specific time. A prospective study monitors a group of disease-free individuals to determine if and when disease occurs. A true experiment involves both an experimental group who receives an intervention and a control group who does not receive an intervention.
