The foreman constantly nags the bricklayers to work faster. When the wall is finished, he stops nagging. This is an example of reinforcement. negative selective singular positive

The answer is negative reinforcement.

Explanation:

In operant conditioning, negative reinforcement occurs when an unpleasant stimulus is removed after a behaviour is completed. In the example, the nagging will stop once the job has been done.

Negative reinforcement has been proved to be more effective than positive reinforcement (rewards).

answer; /// representative democracy restricting trade,is your correct answer;

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
