Ethan is usually talkative and animated when hanging out with his girlfriend, but reserved at home. He actively participates in many classroom discussions in Social Studies but frequently seems to talk with friends at the gym. Ethan's behavior should lead us to question the importance of:

Personality traits

Explanation:

From the example, Ethan has a personality traits

Personality traits has to do with someone's aspect of character, general beliefs, which can be manifested through a set of altitudes, thoughts, values, goals, intentions. it can also be said to be a feeling one inhabits.

In this example, Ethan exhibits different  traits of characters at different times either when he is with his girlfriend or when he is home or actively useful in class, all this are all inferred within him.

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. : )

can you explain it better
