the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?
A. a three-month case study observing the behavior of animals that depend on
mosquitoes for food
B. a survey asking residents about their observations of the local mosquito
population
C. a collection device in the area that counts the number of mosquitoes caught
