Until recently, many anthropologists assumed that the environment of what is now the southwestern United States shaped the social history and culture of the region’s indigenous peoples. Building on this assumption, archaeologists asserted that adverse envi-
line ronmental conditions and droughts were responsible for the disappearances and
5 migrations of southwestern populations from many sites they once inhabited.
However, such deterministic arguments fail to acknowledge that local environmental variability in the Southwest makes generalizing about that environment difficult. To examine the relationship between environmental variation and sociocultural change in the Western Pueblo region of central Arizona, which indigenous tribes have occupied
10 continuously for at least 800 years, a research team recently reconstructed the climatic, vegetational, and erosional cycles of past centuries. The researchers found it impossible to provide a single, generally applicable characterization of environmental conditions for the region. Rather, they found that local areas experienced different patterns of rainfall, wind, and erosion, and that such conditions had prevailed in the Southwest
15 for the last 1,400 years. Rainfall, for example, varied within and between local valley systems, so that even adjacent agricultural fields can produce significantly different yields.
The researchers characterized episodes of variation in southwestern environments by frequency: low-frequency environmental processes occur in cycles longer than one
20 human generation, which generally is considered to last about 25 years, and high-frequency processes have shorter cycles. The researchers pointed out that low-frequency processes, such as fluctuations in stream flow and groundwater levels, would not usually be apparent to human populations. In contrast, high-frequency fluctuations such as seasonal temperature variations are observable and somewhat predictable, so that
25 groups could have adapted their behaviors accordingly. When the researchers compared sequences of sociocultural change in the Western Pueblo region with episodes of low- and high-frequency environmental variation, however, they found no simple correlation between environmental process and sociocultural change or persistence. Although early Pueblo peoples did protect themselves against environmental risk and
30 uncertainty, they responded variously on different occasions to similar patterns of high-frequency climatic and environmental change. The researchers identified seven major adaptive responses, including increased mobility, relocation of permanent settlements, changes in subsistence foods, and reliance on trade with other groups. These findings suggest that groups’ adaptive choices depended on cultural and social as well as envi-
35 ronmental factors and were flexible strategies rather than uncomplicated reactions to environmental change. Environmental conditions mattered, but they were rarely, if ever, sufficient to account for sociocultural persistence and change. Group size and composition, culture, contact with other groups, and individual choices and actions were— barring catastrophes such as floods or earthquakes—more significant for a population’s
40 survival than were climate and environment.
Description
The passage describes research that bears on a presumed historical relationship between environmental variation and sociocultural change among indigenous people of the southwestern United States. The author mentions in the first paragraph that many anthropologists believed until recently that environmental variations explain changes in the human populations of the region. The passage then goes on to point out studies that show problems with this explanation, including the lack of generally applicable characterizations of the environment in the region and lack of correlation between environmental changes and sociocultural changes. In the final paragraph the author mentions an alternative explanation in researchers’ findings suggesting that responses to environmental changes varied according to differing factors such as group size and composition, culture, contact with other groups, and individual choices.
Which of the following findings would most strongly support the assertion made by the archaeologists mentioned in line 3?
选项
A、A population remained in a certain region at least a century after erosion wore away much of the topsoil that sustained grass for their grazing animals.
B、The range of a certain group’s agricultural activity increased over a century of gradual decrease in annual rainfall.
C、As winters grew increasingly mild in a certain region, the nomadic residents of the region continued to move between their summer and winter encampments.
D、An agricultural population began to trade for supplies of a grain instead of producing the grain in its own fields as it had in the past.
E、A half century of drought and falling groundwater levels caused a certain population to abandon their settlements along a riverbank.
答案
E
解析
The archaeologists mentioned in line 3 asserted that adverse environmental conditions caused southwestern populations to move or disappear. The question asks which finding would support this assertion.
Choices A, B, and C all describe populations that did not move away or disappear in the face of environmental changes, and hence are all incorrect. Choice D is incorrect because it does not mention a change in environmental conditions and therefore cannot support an assertion about the effects of changing environmental conditions. Choice E is the best answer: it mentions an adverse environmental change(a long drought)that caused a population to leave the site it had inhabited, which would support the archaeologists’ assertion that such environmental changes caused such population changes.
