Explanation:

• For Question 9: A crude rate is calculated using the entire population in the denominator. Cause - specific rates focus on a particular cause, proportionate mortality ratio is a proportion within deaths, and case - fatality rate is related to cases.
• For Question 10: Secular trends represent long - term changes or trends in disease occurrence over extended periods of time. Single epidemics are isolated events, seasonal trends occur within a year, and point - source epidemics are related to a single source of exposure.
