Historical documents have revealed that among the Timucua., a Native American people of Florida, the best from the hunt or the harvest was given to 5) families of high social status, even in times of economic stress. Archae- ological research suggests a similar relationship between social status and diet in the Dallas communities of eastern 10) Tennessee, prehistoric Native American groups with a social organization and economy similar to that of the Timucua. The first real clue came when archae- ologists discovered that skeletons of 15) 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 20) 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, 25) 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 30) in more remote sections of the settle- ments. The burials actually formed a pattern, the tallest skeletons being found in the mounds, and the heights declining as burials became more 35) 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 40) 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 45) 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 50) 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 55) heavily dependent on edible plants. Very low concentrations of vanadium. Which is scarce in meats and some- What lower in nuts than in other plant Resources, are good evidence of 60) meat consumption and thus a better balanced-diet. As expected, vana- dium was found in considerably greater quantities in skeletons in the burials of lower-status groups. ---------------------------------------------------------------------------------------------------------------------------- Q12 In lines 35_38, the author of the passage raises the possibility that taller people Achieved greater success most probably in order to A) suggest that two explanations for a phenomenon are equally plausible B) introduce empirical data supporting a position C) anticipate an objection to an argument D) question the usefulness of relying solely on physical evidence E) point out a weakness in a traditional argument
答案是(C) 那问NN能帮忙解释一下吗? 谢谢!
