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.

(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.

答案：

题干：因为

本地没有这些动物，而其他地区有相同的图画，所以这些图画是外来工匠创作的。题干说的是“相同图画”和“外来工匠创作”的关系。 A： mosaics 是由哪种石头做得--和题干讨论的内容无关； B：图画上的动物是产自哪里的- 和题干讨论的内容无关； C: 不在该地区出现的图画，在其他地区出现了 - 无关，因为题目讨论的是在该地区出现的图画，没涉及不在该地区出现的图画； D：该地出现的动物图画和已知的物种是相同的 - 无关，不能说明是外来工匠创作的； E：对于在罗马不同地区的artisan来说，并没有一种统一的制图模式。如果没有统一制图模式，那么各地人的风格就是不一样的，如果同一个图案出现在两个不同地方，就证明是出自同一人之手，也就是说这个人travel了。
