Archaeology is a source of history, not just a humble auxiliary discipline. Archaeological data are historical documents in their own right, not mere illustrations to written texts. Just as much as any other historian an archaeologist studies and tries to reconstitute the process that has created the human world in which we live and us ourselves in so far as we are each creatures of our age and social environment. Archaeological data are all changes in the material world resulting from human action or more succinctly the fossilized results of human behavior. The sum total of these constitutes what may be called the archaeological record. This record exhibits certain peculiarities and deficiencies the consequences of which produce a rather superficial contrast between archaeological history and the more familiar kind based upon written records.
Not all human behavior fossilizes. The words I utter and you hear as vibrations in the air are certainly human changes in the material world and may be of great historical significance. Yet they leave no sort of trace in the archaeological records unless they are captured by a dictaphone or written down by a clerk. The movement of troops on the battlefield may "change the course of history", but this is equally ephemeral from the archaeologist's standpoint. What is perhaps worse is most organic materials are perishable. Everything made of wood, hide wool, Linen, grass hair and similar materials will decay and vanish in dust in a few years or centuries save under very exceptional conditions. In a relatively brief period the archaeological record is reduced to mere scraps of stone, Bone, glass, metal, and earthenware. Still modern archaeology, by applying appropriate techniques and comparative methods, aided by a few lucky finds from peat bogs, Deserts and frozen soils is able to fill up a good deal of the gap.
The purpose of archaeology is to learn more about past societies and the development of the human race. Over 99% of the development of humanity has occurred within prehistoric cultures, which did not make use of writing, thereby not leaving written records of themselves that can be studied today. Without such written sources, the only way to learn about prehistoric societies is to use archaeology. Many important developments in human history occurred during prehistory, such as the evolution of humanity during the Paleolithic period, when the hominins developed from the australopithecines in Africa and eventually into modern Homo sapiens. Archaeology also sheds light on many of humanity's technological advances, for instance the ability to use fire, the development of stone tools, the discovery of metallurgy, the beginnings of religion and the creation of agriculture. Without archaeology, we would know little or nothing about the use of material culture by humanity that pre-dates writing.
However, it is not only prehistoric, pre-literate cultures that can be studied using archaeology but historic, literate cultures as well, through the sub-discipline of historical archaeology. For many literate cultures, such as Ancient Greece and Mesopotamia, their surviving records are often incomplete and biased to some extent. In many societies, literacy was restricted to the elite classes, such as the clergy or the bureaucracy of court or temple. The literacy even of aristocrats has sometimes been restricted to deeds and contracts. The interests and world-view of elites are often quite different from the lives and interests of the populace. Writings that were produced by people more representative of the general population were unlikely to find their way into libraries and be preserved there for posterity. Thus, written records tend to reflect the biases, assumptions, cultural values and possibly deceptions of a limited range of individuals, usually a small fraction of the larger population. Hence, written records cannot be trusted as a sole source. The material record may be closer to a fair representation of society, though it is subject to its own biases, such as sampling bias and differential preservation.
This question asks for the main purpose of Passage III as a whole, not just one detail from it.
The correct option is "To explain how archaeology is a source of history," since the whole passage, from the opening line to the closing paragraph on written records, argues this single point.
Let's summarize:
So the main purpose of the passage is to explain how archaeology is a source of history, which is option (C).
This question is a direct lookup question. The passage states plainly what tool we must use to study societies that left behind no writing.
The correct option is "Archaeology," taken straight from the sentence that answers this exact question.
Let's summarize:
So the only way to learn about prehistoric societies, per the passage, is archaeology, option (D).
This is a pronoun reference question. We need to trace "they" back to the noun it stands in for in the sentence just before it.
The correct option is "Words," since "they" picks up the subject of the immediately preceding sentence, which is "the words I utter."
Let's summarize:
So "they" refers to words, option (B).
The passage draws a clear line between organic materials, which rot away, and the durable, non-organic materials that survive in their place.
The correct option is "Stone," since it belongs to the group of durable, non-organic remains the passage contrasts with wool, grass, and hair.
Let's summarize:
So the material that is not organic is stone, option (A).
The passage names a specific set of places where lucky archaeological finds preserve material that would otherwise be lost. We need to find the one option that is not part of that list.
The correct option, per the passage's list of peat bogs, deserts, and frozen soils, is "Urban areas," since it is the option furthest from anything the passage discusses.
Let's summarize:
So the site not mentioned by the author is urban areas, option (A).
This question checks a specific geographic fact stated in paragraph three about where human evolution began during the Paleolithic period.
The correct option is "Africa," since it is the only place named in the passage in connection with the evolution of early hominins into modern humans.
Let's summarize:
So the beginning of human evolution during the Paleolithic period took place in Africa, option (D).
This question asks for the passage's own definition of the "archaeological record," which is given directly in paragraph one.
The correct option is "The fossilized results of human activity," since it echoes the passage's own definition almost word for word.
Let's summarize:
So the archaeological record consists of the fossilized results of human activity, option (B).
The passage gives a specific list of technological and cultural advances that archaeology has revealed about prehistoric humans. We need to find the one option that is missing from that list.
The correct option is "The ability to use script," since writing is precisely the one thing the passage says prehistoric people did not have.
Let's summarize:
So the technological advance not mentioned in the passage is the ability to use script, option (E).
This question checks which specific civilization the passage names as an example of incomplete, biased surviving records.
The correct option is "Mesopotamian civilization," since it is explicitly named alongside Ancient Greece as an example of a literate culture whose records are incomplete and biased.
Let's summarize:
So the civilization whose surviving records are called incomplete and biased is Mesopotamian civilization, option (C).
