Answer:
Stone were used
Bone
Explanation:
Throughout the Paleolithic, humans were food gatherers, depending for their subsistence on hunting wild animals and birds, fishing, and collecting wild fruits, nuts, and berries. The artifactual record of this exceedingly long interval is very incomplete; it can be studied from such imperishable objects of now-extinct cultures as were made of flint, stone, bone, and antler. These alone have withstood the ravages of time, and, together with the remains of contemporary animals hunted by our prehistoric forerunners, they are all that scholars have to guide them in attempting to reconstruct human activity throughout this vast interval—approximately 98 percent of the time span since the appearance of the first true hominin stock. In general, these materials develop gradually from single, all-purpose tools to an assemblage of varied and highly specialized types of artifacts, each designed to serve in connection with a specific function. Indeed, it is a process of increasingly more complex technologies, each founded on a specific tradition, that characterizes the cultural development of Paleolithic times. In other words, the trend was from simple to complex, from a stage of nonspecialization to stages of relatively high degrees of specialization, just as has been the case during historic times.
In the manufacture of stone implements, four fundamental traditions were developed by the Paleolithic ancestors: (1) pebble-tool traditions; (2) bifacial-tool, or hand-ax, traditions; (3) flake-tool traditions; and (4) blade-tool traditions. Only rarely are any of these found in “pure” form, and this fact has led to mistaken notions in many instances concerning the significance of various assemblages. Indeed, though a certain tradition might be superseded in a given region by a more advanced method of producing tools, the older technique persisted as long as it was needed for a given purpose. In general, however, there is an overall trend in the order as given above, starting with simple pebble tools that have a single edge sharpened for cutting or chopping. But no true pebble-tool horizons had yet, by the late 20th century, been recognized in Europe. In southern and eastern Asia, on the other hand, pebble tools of primitive type continued in use throughout Paleolithic times.
Answer:
Perceptual set
Explanation:
Perceptual set: In psychology, the term perceptual set is described as a set that consists of a few expectations which lead to shape an individual experience by making him or her sensitive to certain kind of information.
The perceptual set is also referred to as the perceptual expectancy that refers to an individual's predisposition of perceiving things in specific ways and therefore avoiding other details related to those things. It can arise in various senses.
Factors that affect an individual's perceptual set includes culture, motivation, and personal experiences, etc.
In the question above, the given statement best illustrates the impact of perceptual set.
The correct answer is letter B
Explanation: In this sense, the best answer is the letter B, because when looking for a new space for production and for the company, the most normal is to increase the workforce, as it is a way to increase the company's earnings so that this new place can get paid.
Mongolia was a part of China before 1900.
In 1911 though, Mongolia became independent.
A command economy is a system where the government, rather than the free market, determines what goods should be produced, how much should be produced, and the price at which the goods are offered for sale. It also determines investments and incomes. The command economy is a key feature of any communist society.
