1.        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?

1. The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.

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

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

4. All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

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

答案是E，有人可以解释一下为何D错？E又为何对吗？

D 与结论无关，本题的出题点在于 最后一句话的结论 与前提的桥梁缺失，所以假设肯定是与其有关， 而E 选项如果取非，则明显不能退出该结论，所以为正确答案， repertory 这里的意思为轮演， 这句话正确语序是说，Artisans who lived in various parts of the Roman Empire were unfamiliar.with common repertory of mosaic designs ,

还是不懂

Sepphoris挖出来大量不在本地生存过的动物mosaics .   the mosaics of Sepphoris 像个游客们带来的。mosaics .   the mosaics of Sepphoris 像个游客们带来的。

假设：有个大仓库 repertory
                        ，用来供不同部分的艺术家们共同使用（放些各自的作品，如果这样了，就可以互通有无了）

新手请教楼上高手：我在GWD中只看到13套题，为什么它的编号是23-32，难道GWD有23套题，其中每套题有若干题吗，怎样才能用编号去找题？

试着解释哈：
        

E：要表达的意思是原来住在Roman Empire不同地方的人们， 是没有个一个共同的“资料库”。 这个“资料库” 是一个能使全部人都对所有的 mosaic designs 熟悉的资料库。 也就是说，在原来居住在不同Roman Empire 地方的人每一个地区都有自己独特的mosaic designs ，而其他地方的人对于另外一个地方的mosaic designs 都不熟 悉。正是这一点保证了S城的mosaic designs 一定是外面的人带来的，而非S城本城的人自己创作的（或从别人那里学来的）

D 说的是所有的这些mosaic designs 里的物种都是已知物种

不知道说明白了没。。。

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

不是正好说的就是motifs appear 不都是外来的么？为什么C不可以呢？

C说S这里不出现的东西，其他地方也没有。很正常啊，S这里没有外星人，其他地方也没有外星人，这并不影响结论：壁画可能是外来人画的

E：打个比方，A和B是朋友，B一直拿OG的题来考A，A从来没读过OG，突然A在网上看到一道OG的题，说这是我一个朋友B写的。C嘲笑道，你去新东方门口买本OG就知道不是B写的了。
