长阅读 transmission ancient Roman texts 求解
The history of the transmission of ancient Roman texts prior to invention of the printing press is reconstructed from evidence both internal and external to the texts themselves. Internal evidence is used to reconstruct the relationship of the surviving manuscripts of a Roman text to one another, as represented in a modern stemma codicum: a diagram depicting the genealogical relationship of surviving manuscripts and those the stemma’s editor believes existed at one time. Stemma are scholar’s only road maps to textual connections based on internal evidence, but they may paint a distorted picture of reality because they diagram the relationships of only those manuscripts known or inferred today. If surviving copies are few, the stemma perforce brings into proximity manuscripts that were widely separated in time and place of origin. Conversely, the stemma can also bestow a semblance of separation on manuscripts written within a few months of one another or even in the same room.As described in the passage, a stemma is most closely analogous to which of the following?
A. a department store inventory list that excludes some departments
B. a map from which a large section has been torn off
C. a chronology that includes only major historical events
D. a family tree in which some generations are not recorded
E. a government organizational chart from which some agencies are omitted
我选了E，答案D，照理来说应该是根据段尾部分对于stemma的解释来对应题干选答案，但是看了D选项想了很久不知道怎么把它和文中对于stemma的解释对应上去.....求大神分析段尾后两句 自己顶一下 stemma这个词的意思就是family tree。除此之外，这个词genealogical也在提示，它的大致意思是与家族谱系相关的。
和government organizational chart相比，stemma的比喻可以体现时间的演进。
最后两句的用意是在于解释前面那句：“they may paint a distorted picture of reality...”，即stemma法的局限：如果谱系演进树缺失了，则可以造成前后关系推断的不精准，以及产生假象。
hope this helps~
