Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable anima
l 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.
B. This answer doesn't address how knowledge of species only got to Sepphoris from travelling artisans
C Interesting answer choice, but it could support traveling artisan conclusion or a common knowledge base of species across all of Rome.
D. This runs counter to the conclusion- If the species are known then any artisan (not necessarily a traveling artisan ) could have created the mosaics.
E. This option states that there isn't a common knowledge base of species which supports the conclusion that only traveling artisans cold have created the mosaics.
