Answer to Question 1

D

Answer to Question 2

Three different methods can be used to quantify the behavior. (1) The frequency method would involve recording how many times each rat eats during the observation period. (2) The duration method would involve recording how much time each rat spends eating during the observation period. (3) The interval method would involve dividing the observation period into intervals (for example, one-minute intervals) and then recording whether or not each rat eats during each interval. (p. 366-367)
