Answer to Question 1

A PROSPECTIVE STUDY IS A BETTER PROCEDURE BECAUSE PEOPLE OFTEN DO NOT REMEMBER PAST EVENTS ACCURATELY.

Answer to Question 2

ANY TWO OF THE FOLLOWING ARE OK: EFFICIENCY IN TERMS OF TIME OR MONEY; NOT HAVING TO WORRY ABOUT THE ETHICS INVOLVED IN RANDOMLY ASSIGNING PEOPLE TO EITHER HARMFUL OR BENEFICIAL TREATMENTS; AND INCLUSION OF ENOUGH PEOPLE WITH THE CONDITION YOU ARE STUDYING.
