gwd23-Q32不明白选项

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?
     

• The Sepphoris mosaics are not composed
       exclusively of types of stones found naturally in the Sepphoris area.
• There is no single region to which all
       the species depicted in the Sepphoris mosaics are native.
• No motifs appear in the Sepphoris
       mosaics that do not also appear in the mosaics of some other Roman city.
• All of the animal figures in the
       Sepphoris mosaics are readily identifiable as representations of known
       species.
• There was not a common repertory of
       mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

请大家帮我讲讲这个题，题目读懂了，可是每个选项都读不明白。也看不出来选项和题目的联系。

正确答案是Ｅ。我第一次选了Ａ，　第二次选了Ｂ．

原文大意：

因为——S城的马赛克上出现了异地物种图案

所以——这个马赛克是异地画家画的。

关键词：

因为——异地物种

所以——异地工匠

比较：物种=工匠

答案中应该存在以上两个关键词。

E选项实际上是：There was not a common repertory of mosaic designs which artisans who lived in various parts of Roman Empire were familiar with.

with 修饰的是主语repertory。但GMAT考试中，要求定语从句中的介词要提到联结词which前。而且句子不能以介词结尾。这正是语法的考点之一。

因此，E选项的意思就明白了：罗马帝国的不同地区的工匠们（工匠）并没有一个他们都熟悉的马赛克设计图库（物种图样）。这句话中存在了两个关键词，所以正确。

A的意思是：S城的马赛克并不是仅仅用当地的石料加工而成的。

B的意思是：S城的马赛克所描述的物种并非产于某一特定区域。与E同理，to which...native=which...native to

这道题目只要抓住argument想说明马赛克是异地工匠做出来的，而不是本地工匠做出来的。但是如果本地工匠盒异地工匠用同样的图库，那这些马赛克就有可能是本地工匠做的。就明白了

谢谢楼上的同学们，我懂了。

这个题我觉得是D， 因为前面花了篇幅写Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.   而不是说什么技术怎么怎么样。有人讨论一下么

D项，是不是known species和主题无关
