Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600's are remarkably complete. This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines. Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was computed by the central government using the annual census figures. Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village's population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen.
In the historian's argument, the two portions in boldface play which of the following roles?
The first supplies a context for the historian's argument; the second acknowledges a consideration that has been used to argue against the position the historian seeks to establish.
The first presents evidence to support the position that the historian seeks to establish; the second acknowledges a consideration that has been used to argue against that position.
The first provides a context for certain evidence that supports the position that the historian seeks to establish; the second is that position.
The first is a position for which the historian argues; the second is an assumption that serves as the basis of that argument.
The first is an assumption that the historian explicitly makes in arguing for a certain position; the second acknowledges a consideration that calls that assumption into question.
注意historians的论点只在文章最后一句出现：这个report报告的下降可能并没有发生；全文没有转折
因此前面陈述的都是一个事实/context:This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines. 尤其这句很有迷惑性，做题的时候会认为是论点，其实只是对于事实的进一步陈述而已
错选E，第二黑是结论，应该看到acknowledges就可以删掉了，结论词只有conclusion / position
BF2 指明的是report中decline发生，但是现实中的decline没有发生。
所以二者一派，支持关系。
整个文中也没有however这类明显的转折词。都是句子之间都是顺承关系。
ABDE都错，因为没有argue也没有calls into question。
只有C，两个BF都是逻辑上同方向的。
b2 前有therefore, 说明不是assumption
第二个黑体就是main conclusion
我哪里理解错了呢5555555
整段话都是historian说的，也就是说第二个黑体表示的结论就是historian的结论，那就不应该是B里所说的against that position了登录 或 注册 后可以参加讨论
数据证明每次税收增加之后都会伴随人口减少（事实）
因为：税收增加，政府有economic incentive 去minimize人口数
结论：报告中的人口减少并没有实际发生
BB=black bold
CC=cencuses report
P=population
T=tax
context=背景、上下文
BB1= CONTEXT / ASSUMPTION, B,Dwrong
A: to argue against the position the historian seeks to establish. wrong,
E: an assumption that the historian explicitly makes in arguing for a certain position; not explicitly, the assumption serves as context for evidence.
