Historical documents have revealed that among the Timucua, a Native American people of Florida, the best from the hunt or the harvest was given to families of high social status, even in times of economic stress. Archaeological research suggests a similar relationship between social status and diet in the Dallas communities of eastern Tennessee, prehistoric Native American groups with a social organization and economy similar to that of the Timucua. The first real clue came when archaeologists discovered that skeletons of higher-status individuals tended to be several centimeters taller than those of people of lower states.

In the largest Dallas communities, some individuals were buried in the earthen mounds that served as sub-structures for buildings important to civic and religious affairs. These burials included quantities of finely carried items made of nonlocal material, denoting the high political standing of those interred. Burials of lower-status individuals contained primarily utilitarian items such as cooking vessels and chipped stone tools and are located in more remote sections of the settlements. The burials actually formed a pattern, the tallest skeletons being found in the mounds, and the heights declining as burials became more distant from the mounds. While it is possible that taller people were simply more successful in achieving high social standing, it is more likely that a number of stresses, including those resulting from a relatively poor diet, which could affect stature, were common among the lower-status groups Excavations indicate that where food categories made up the bulk of the population’s diet: agricultural crops cultivated in the fertile alluvial soils where the communities were located, game, and wild edible plants, primarily nuts. Information about dietary variation among community members is derived by analyzing trace elements in human bone. Higher than normal levels of manganese, strontium, and vanadium probably indicate a less nutritious diet heavily dependent on edible plants. Very low concentrations of vanadium, which is scarce in meats and somewhat lower in nuts than in other plant resources, are good evidence of meat consumption and thus a better balanced-diet. As expected, vanadium was found in considerably greater quantities in skeletons in the burials of lower-status groups.


In highlight, the author of the passage raises the possibility that taller people achieved greater success most probably in order to

    文章大意逻辑
    文章开篇指出历史文献显示佛罗里达的蒂穆夸人中,狩猎或收获的最好成果会给社会地位高的家庭,考古研究表明田纳西东部达拉斯社区的史前美洲原住民群体中社会地位和饮食也有类似关系。接着详细描述达拉斯社区中不同社会地位的人的墓葬情况,地位高的人墓葬有精美物品且在重要位置,地位低的人墓葬物品普通且位置偏远,且墓葬中骨骼高度呈现从中心向远处递减的模式。然后提出虽然有可能高个子的人更容易获得高社会地位,但更可能的是社会地位低的群体常面临食物等方面压力从而影响身高,还介绍了通过分析人骨微量元素了解饮食差异的信息。 文章类型及逻辑简图
    文章类型:现象解释型 逻辑简图: Historical documents: Timucua best from hunt/harvest to high status families Archaeological research: Dallas communities similar relationship between social status and diet Burial details in Dallas communities: high status in mounds with fine items, low status with utilitarian items in remote sections, height pattern in burials Explanation of height social status relationship: two possibilities (taller for high status or poor conditions for low status affecting height) Diet information: from analyzing trace elements in human bone 做题方法及问题类型
    问题类型为推断题,做题方法是通过定位到文中“While it is possible that taller people were simply more successful in achieving high social standing, it is more likely that a number of stresses, including those resulting from a relatively poor diet, which could affect stature, were common among the lower status groups”这句话来推断作者提出高个子的人可能取得更大成功的意图。 选项分析
    A选项:文中并没有表明两种对现象的解释同样合理,属于无中生有,排除。 B选项:文章此处并不是在引入支持某种立场的实证数据,与原文逻辑不符,排除。 C选项:作者提出高个子可能取得更大成功这种可能性,是为了提前回应可能有人认为是高个子导致高社会地位这一反对观点,符合文意,当选。 D选项:文章此处重点不是质疑仅依靠物理证据的有用性,排除。 E选项:文中没有提及传统观点的弱点,排除。
