Please check my answer thanks:)

After a dog learns to perform a specific task, the task must then be generalized to various locations. The task must then be _______, so that the dog is able to perform the response despite any distractions such as crowds, noises, or moving objects.

A. proofed
B. altered

C. relearned

D. certified

I picked D

I would say B -- the dog needs to learn to perform the particular task in a variety of circumstances, right?

The correct answer is A. "proofed". When we say a task must be "proofed", it means that it needs to be practiced in different locations and under various distractions. This helps the dog to generalize the learned behavior and be able to perform it consistently regardless of the surroundings or distractions present.
