GWD17想不通

Excavations of the Roman city of Sepphoris have uncovered numerous detailedmosaics depicting several readily identifiable animal species:  a hare, a partridge, and variousMediterranean fish.  Oddly, most of thespecies represented did not live in the Sepphoris region when these mosaicswere created.  Since identical motifsappear in mosaics found in other Roman cities, however, the mosaics ofSepphoris were very likely created by traveling artisans from some other partof the Roman Empire.

Which of the following is an assumption on which theargument depends?

A.     The Sepphoris mosaics are not composedexclusively of types of stones found naturally in the Sepphoris area.

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

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

D.     All of the animal figures in the Sepphorismosaics are readily identifiable as representations of known species.

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



为什么D不对?我的逻辑是——前提假设:图案都是人们当时熟知的动物    结论:那些马赛克不是本地人做的

事实:**城市发现了动物图案马赛克—**这些动物在当时的城市没有——结论:马赛克是别的城市的游客创造的
要找寻前提的话,前提必须和结论相关,而D(图案上的动物是人们熟知的)与结论完全不相关——不相关即:既不加强结论也不削弱结论,同样与结论无任何因果联系。所以D肯定是直接排除的。
