How does the following excerpt from a classroom speech violate the guidelines for supporting materials presented in your textbook? according to a study earlier this year by the meyers survey research company funded by mcdonald's, there is no clear correlation between obesity and the consumption of fast food.

It doesn't present information from an unbiased source.

Explanation:

The survey research is based solely on one business or company which conducted this survey and McDonald is a company that sells food which may be critized by health experts as the kind of food which when is eaten constantly will result to obesity.

Chances are when a company conduct a survey which may affect the operation of their own business it is very likely that they may distort the results to ensure this doesn't stab them at the back.

No one will wants to say anything that may jeopardize their own operation and probably put them out of business or lower the number of their customers .

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. : )
