Q19:

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.

这题选C. 我选了E.  翻看以前的讨论帖子. 发现是说Historian的position是 reported declines did not happen.  这点并没有否定Village census records for the last half of the 1600’s are remarkably complete这一点. 就象削弱题中不能削弱推导的前提一样.  这个我理解了.

可是疑惑在于,C中, The first provides a context for certain evidence that supports the position.   我看不出来这个context哪点support 历史学家的position了?  这只是个调查数据的情况, 并没有支持历史学家观点的证据, 而且最后的观点的得出,是建立在它因,即tax went up 促使了conceal the record的基础上的.   context for certain evidence的支持作用如何理解呢??

另: BF题到底该如何做呀?  我用以前许多NN的方法,即只看标志词, since, therefore, but之类, 注意逻辑结构,不注重内容.  可是几乎每次做BF都错光光. GWD5这套的两道BF题,19,20 我全错了.  不知道如何是好了~!~   

大家有什么好的方法吗? 该怎么办?

恳请大家赐教!!!

The first provides a context for certain evidence that supports the position.这句话是说第一处是证据的一些内容,而这些证据是支持position的,
