Excavations of the Roman city of Sepphoris

have uncovered numerous detailed mosaics depicting several readily identifiable animal species:a hare, a partridge, and various Mediterranean fish.Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

Which of the following is an assumption on which the argument depends?

1. The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.
   
   
2. There is no single region to which all the species depicted in the Sepphoris mosaics are native.
   
   
3. No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.
   
   
4. All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.
   
   
5. There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.
   
   答案是E，估计是自己连意思都没看懂，请大家帮忙看看~~~~~~~~

关键的premise1：most of the species represented did not live in the Sepphoris region when these mosaics were created
premise2： identical motifs appear in mosaics found in other Roman cities
conclusion：the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

分析：mosaics of Sepphoris 完成创造的时候，上面所呈现的物种并不生活在S； identical motifs appear in mosaics 在其他城市也有。结论：the mosaics of Sepphoris 是由其他城市（不是S）的traveling artisans 完成的。

简化：因为S没有这些物种，而这些物种的图案在其它城市有被发现，推出结论mosaics是由其它城市的traveling artisans 完成的。（隐含S没有这种物种，S的艺术家不可能描绘出这种物种的图案）

选项E：There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.
当时没有一些普遍的图案是罗马帝国许多城市的艺术家都熟知的。

这是一个defender：去掉not 当时有一些图案是艺术家都普遍熟知的。则会对原文造成削弱。则表示即使S没有这种物种，S的艺术家依旧可以描绘出这种图案！

个人看法，希望大家指点！THX

排除法:
A 讨论的是composition ,和题目所问无关
B Native与否也无关
c 是重复题干里的原话Since identical motifs appear in mosaics found in other Roman cities，未构成解释
D讨论是否是已知物种 ，也无关
E 居住在罗马帝国各个地方的艺术家之间就设计没有共识 就是说有的本地艺术家不熟悉的可能外地的艺术家可以帮助完成，对应Conclusion "were very likely created by traveling artisans from some other part of the Roman Empire"
