Answer:
When Jaspreet makes his bed and the nagging stops, he is negatively reinforced.
Step-by-step explanation:
A negative reinforcement is a response or a behavior which is reinforced, strengthened, by stopping the negative outcome of the aversive stimulus. In other words, a negative reinforcement, just as in the example provided by the exercise, is an action which is done only to prevent a negative action. Jaspreet is nagged if he does not make his bed. Therefore, he does so. But, if he wasn't nagged, he would not make it. You engage in an action in order to avoid a negative result.
