Your text defines learning as the process of acquiring new and relatively enduring information or behaviors. why would a behavior or information have to endure in order to be considered learned?

The answer to this question is 
-associating two events with each other (so we could form a direct cause-effect relationship between the two events)
-two stimuli (classical conditioning) (in order to understan how a certain reponse is being triggered)
-response and consequence (operant condition) that could determine reward and punishment that exist if we change a certain behavior.
