B. shifting
Explanation:
In any market, the price can be studied in two perspectives. That of the buyer, who uses it as a reference of potential utility, and that of the seller, for the one or which means first a guide of the possible income of his activities and, secondly, the method by which he converts them into profits.
From this point of view there are several concepts that should be kept in mind: price of offer, or price at which the seller offers his merchandise. Demand price is what a consumer is willing to pay. Market price or observed prices are the prices at which real purchases took place.
In a theoretical situation -free market- the price would be fixed by the law of supply and demand.In the case of a monopoly the price "is on each occasion the highest that can be squeezed out of the buyers, or the one that , it is supposed, they will consent to give. "
In a real situation - of imperfect competition - prices are determined through other mechanisms, such as the maximization of marginal income (see also oligopoly, oligopsony, monopolistic competition, Stackelberg competition, web theorem, etc.)
Hunter-gatherers were prehistoric nomadic groups that harnessed the use of fire, developed intricate knowledge of plant life and refined technology for hunting and domestic purposes as they spread from Africa to Asia, Europe and beyond. From African hominins of 2 million years ago to modern-day Homo sapiens, the evolution of humans can be traced through what the hunter-gatherers left behind—tools and settlements that teach us about the hunter-gatherer diet and way of life of early humans. Although hunting and gathering societies largely died out with the onset of the Neolithic Revolution, hunter-gatherer communities still endure in a few parts of the world.
