After congress has approved a proposed amendment to the constitution, what then must take place before that amendment becomes law? the president must approve it. three-quarters of the states must approve it. the supreme court must approve it. half of the states must approve it.

Three-quarters of the states must approve it.

Explanation:

Amendment to the constitution will heavily influenced the type of laws that can be passed by the states (since they are not allowed to contradict the laws from the constitution.)

Because of this, the amendment will require the approval of the large majority of the states to maintain the stability of the government on local levels.

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.
