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.

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

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.

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

问，按取非削弱来做c也应该是对的啊，c是:所有的动物都出现在了其它的罗马城中，如果取非的话句是没有出现了，是对原文的削弱啊？请nn们解答

自己顶了，不可取非前提。呵呵

D ？

d?

c双重否定，去掉两个否定以后感觉就是原文陈述的事实
