19. GWD-23-Q32

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?

A.      The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.  (无关)

B.       There is no single region to which all the species depicted in the Sepphoris mosaics are native.
            无关

C.       No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.

D.      All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.
            无关

E.       There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

请问该如果对C、E 取非？

C 是取非no, 还是 do not

E 不是很明白意思，，请教，谢谢！！！

some motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.

/No motifs appear in the Sepphoris mosaics that do also appear in the mosaics of some other Roman city.

仅为取非两个都行，语气不同，但是后者与文章信息有悖，所以该题前者是正确的取非。

E,说的是在roma的各个地方，对 mosaic designs 没有一个通用的剧目，排出他因，是答案。
