Answer to Question 1

ANS: B
Selection bias is attributable to the way subjects enter a study. It has to do with selection proce-dures and the population from which subjects are drawn. Determining the population to be stud-ied relates to the design of the study. Studying cause and effect relationship has to do with eco-logical studies. Documenting the results of the study is completed at the end of the study after the participants have been selected.

Answer to Question 2

ANS: B, C, D
Collection, reporting, analysis, and interpretation of data, environmental risk communication, and documentation on patient charts and records are examples of the use of epidemiology in practice. Policy making and law enforcement do not apply to epidemiology.
