Regulations under the federal trade commission's advertising substantiation program established that supposed experts used in advertisements must be qualified experts in their field, and celebrities must the products they endorse.

use      

Explanation:

The answer is -- "use".

               The Federal Trade Commission was established as a independent agency in the US government. It was established at the year 1914.

               The main purpose of the Federal Trade Commission was to prevent illegal methods and unfair means of competition in business and commerce that they use to advertise their product.

              Under the regulation of Advertising Substantiation Program as laid down by the Federal Trade Commission of the US, the experts those who are used in the advertisement must be a qualified and experts in that respective field and the celebrities whose stardom is used to influence people by showing them in the advertisement must also use the mention product that they endorse.

Thus the answer is -- "use".

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. : )
