Suppose that you're going to interview someone in preparation for writing a research paper on teaching techniques for macroeconomics. for this topic , who would be the best person to interview? a. an economist b. the president of a university c. a student in a macroeconomics course d. a professor of macroeconomics

d. A professor of macroeconomics

Explanation:

Since this writing research is going to be about "Teaching Techniques", the professor  is the best option. All the others might be well familiarized with macroeconomics, but the expert on teaching techniques is the only one who actually teaches, and that is the professor.

normally working animals are domesticated and ruled by a master, a domesticator (tamer), to perform basic and important functions on a farm, for example. the value used in this context is animal labor in exchange for food. it is not so much a contrast to the story told by napoleon and the pigs, since the animals of that particular farm also performed functions on the farm through domestication. the only thing is that in this case, who rules them is a pig, also an animal, but very respected, to whom the other animals lent him submission. that's about a strong relationship of dependency between animal and owner.
