Samples from a ceramic vase found at a tomb in Sicily prove that the vase was manufactured in Greece. Since the occupant of the tomb died during the reign of a Sicilian ruler who lived 2,700 years ago, the location of the vase indicates that there were trade between S and G 2,700 years ago. Which of the following is an assumption on which the argument depends? A. S potters who lived during the reign of the ruler did not produce work of the same level of quality as did G potters. B. S clay that was used in the manufacture of pottery during the ruler’s reign bore little resemblance to G clay used to manufacture pottery at that time C. At the time that the occupant of the tomb was alive, there were ships capable of transporting between S and G D. The vase that was found at the S tomb was not placed there many generations later by descendants of the occupant of the tomb. E. The occupant of the tomb was not a member of the royal family to which the S ruler belonged. An: D, 错选了A。 刚开始怎么都想不明白,后来在仔细看,发现结论是“the location of the vase”,即“这个花瓶的位置”,强调的是位置,那么如果是这样的话,觉得肯定是D了,因为只有D明确了地点。不知道思路是否正确,open to discuss!
