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

weekly

D. a controlled lab experiment with mosquitoes that limits watercolor the

experimental group
