Cathy carefully walks down the aisle of the dark movie theatre. after hesitating a few times, she finds an empty seat. after a short while she can distinguish her friend suzy sitting a few rows ahead of her. cathy has experienced the phenomenon known as:

dark adaptation                      

Explanation:

Dark adaptation: The term dark adaptation refers to the phenomenon through which an individual's eyes can adjust to darkness after he or she has been exposed to light for a specific period. Eventually, the eyes adapt to the darkness by recovering it and becomes more sensitive in dim light. It happens after the pupils of a person gets dilated and changes or alters the cones and rods of the person's eyes.

In the question above, Cathy has experienced the phenomenon known as dark adaptation.

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. : )
