Agroup of researchers wanted to investigate allegations of sexual harassment on a company's assembly line. to make their observations, they took jobs working on the assembly line and pretended to be new employees. the best, most precise term to describe what the researchers were doing is

This is a Naturalistic observation.

Explanation:

What is a Naturalistic observation?

This is a research which involves observing people or animals or objects in their natural environment.

People or animals acts natural in their normal self when they don't feel like they are contained or constrained for observational purposes.

This is usually chosen if subjects to be studied will have their behaviour affected by being in a constrained environment such as the laboratory.

This will help researchers understand how people react to certain stimulant in real life when they are in their comfort natural environment.

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. : )

it´s related to his charming character.

beauty is not everything, although we can joke that girls only care about the physical or material aspect, the truth is that a real woman looks at more important things, besides intelligence and personality, there are other attitudes that make irresistible to men who are 'unattractive'.

for example develop your sense of humor.
