Answer to Question 1

A
A cross-sectional study collects information on current health status, personal characteristics, and potential risk factors or exposures all at once.

Answer to Question 2

B
One temporal and spatial pattern of disease distribution is the point epidemic. A point epidemic is most clearly seen when the frequency of cases is plotted against time. The sharp peak charac-teristic of such graphs indicates a concentration of cases in some short interval of time.
