The rules of experimentation suggest: a. word of mouth is a useless data source b. three experts must agree on a topic before it is said to be a fact c. ignoring negative information d. six pieces of information saying the same thing can be a fact

A. Word of mouth is a useless data source.

Explanation: Experimentation refers to an empirical procedure or process which is used to validate an hypothesis or establish a fact. However, experimentation requires rules which guides the process, these rules are necessary in other to avoid bias, false conclusions or inference.

According to the options given in the question above, facts used in experimentation should be traceable and reproducible. Word of the mouth is a useless data source as it usually has no empirical basis. Expert opinion or information being established by three or six sources could be considered as a fact.

answer; /// i believe its(c) policymakers prioritize the various problems facing the state;

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. : )
