114.

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.

ANS: E 想請問C選項是 weaken嗎~? 沒出現在 Sepphoris mosaics 的主題~也沒出現在其他的mosaics~! 還有A選項是不是~有可能是本地的artisan去外地找stones~所以此選項不成立呢?? E選項是不是說有待過很多地方的artisan 並沒有熟悉的 common repertory of mosaic designs ~~所以表示是從other Roman cities來的呢~?? 多謝~~大家指點~!!!
