82. Excavation of the ancient city of Kourion on the laceType>islandlaceType> of laceName>CypruslaceName> revealed a pattern of debris and collapsed buildings typical of towns devastated by earthquakes. Archaeologists have hypothesized that the destruction was due to a major earthquake known to have occurred near the island in A.D.365.

Which of the following, if true, most strongly supports the archaeologists’ hypothesis?

A. Bronze ceremonial drinking vessels that are often found in graves dating from years preceding and following A.D.365 were also found in several graves near Kourion.

B. No coins minted after A.D.365 were found in Kourion, but coins minted before that year were found in abundance.

C. Most modern histories of Cyprus mention that an earthquake occurred near the island in A.D.365.

D. Several small statues carved in styles current in Cyprus in the century between A.D.300 and 400 were found in Kourion.

E. Stone inscriptions in a form of the Greek alphabet that was definitely used in Cyprus after A.D.365 were found in Kourion.

答案是B。OG对C答案的解释是Since choice C supports something already established, namely, that an earthquake occurred in A. D. 365, C is inappropriate。但是仔细想想B答案确实存在漏洞——那种coin可能是在A.D.365之后不再生产了，但是城市还在存续。而C答案，考古学家认为城市毁于地震，资料（C答案）就显示确实存在那么一个地震。由此看来，C答案是不是更好一些。

请高手指教。

支持既可以不充分，也可以不必要；文章中既然已经给出了地震发生的时间/地点，答案中重新给出改写，起不到任何加强的作用。

题目告诉你两个信息,一个是发现残骸,还有就是AD365有地震,结论就是残骸是由于地震.

问的是哪一个可以加强结论.

C只是把原来的再说了一次.没法加强

而B是提供了一个新的证据.

这里不能够说题目中已经给出了地震的时间吧。题目的结论是地震发生在365年，好像不是使得结论成立的一个充分条件。而选项C则可以看作一个充分条件。

请NN讲讲为什么365年是题目中给出的使得结论成立的条件。

谢谢。

By contrast, choices A, D, and E all give information about artifacts found in or used in Kourion, but they do not specifically point to A. D. 365 as the date of the devastation. Thus, A, D, and E are inappropriate.

而我的看法是：

(A) Bronze ceremonial drinking vessels that are often found in graves dating from years preceding and following A.D.365 were also found in several graves near Kourion.--既然是following.那么就应该是weaken 啊。。

(D) Several small statues carved in styles current in Cyprus in the century between A.D.300 and 400 were found in Kourion--between 300 和400 之间，那么就有365以后的了。那么就应该也是weaken 的呀！~

(E) Stone inscriptions in a form of the Greek alphabet that was definitely used in Cyprus after A.D.365 were found in Kourion.

都是对这几个选项中的时间发生疑问。觉得这几个选项都是weaken而不是属于inappropriate的。

请指教，偶的思考哪里出了问题呢？inappropiate应该是不等于weaken的吧！～

多贴一遍

以下是引用laserlee1在2004-5-19 11:49:00的发言：

题目给了2个事实

1。城市毁于地震

2。AD 356 ，城市所在的岛发生过地震

结论城市毁于AD356的地震对这个结论很正确，而且特别说明了时间，注意。

但事实上，光凭以上2点不能100%得出结论，城市也完全可能是毁于其他时间。很对。

B 给出第3个FACT进行SUPPORT——城市遗迹里无AD356以后的COIN ，却有之前的。注意：这个只能证明城市不可能被AD356之后的地震摧毁（而且这个推断也不一定成立，见我蓝色部分分析），并不能证明就是被AD365哪一年的地震摧毁。难道光凭题目和选项B可以推出city of Kourion 是毁于AD365，而不是AD365之前发生地震的任何一年，因为没有信息表明就只有在AD365哪一年才发生地震，其他任何时间没有发生地震。还有一个事实情况是：COIN是AD365钱铸造的，但是大家有没有用过任何一种当年铸造或印刷货币，没有吧。而且，一种货币就只能在当年使用，过期无效吗？AD365之后就不会用AD365或AD365之前铸造或印刷的货币吗？要是这样的话，大家赶快把身上所有人民币都给我吧（今年新出的50元可以不给，但是其他的都要给啊，反正大家都没有用，而且也不用^_^）。

C只是对事实2进行了重复讲述而已我认为：C没错是对事实2进行了复述，但是不能理解为对事实2证据的支持吗，证明结论的事实是确实存在发生了的，难道不就可以支持结论吗？WEAKEN不就有削弱证据而削弱结论，为何支持不能支持证据而支持结论。lawyer_1的CR方法SUPPORT中因果型就有“D显示因果关系的资料是准确”的说法，本题的C就是显示因果关系的事实是准确的。

这里问一下lawyer_1或其他NN，SUPPORT非要提供新的信息吗，难道不可以出现像lawyer_1所说的显示因果关系的资料是准确的这样的情况吗？

wingkim · 发表于 2005-10-26 21:12:00

用数理逻辑来理解：

X:城市毁于地震

Y:AD 365 的地震

Z:结论城市毁于AD365的地震那么Z=X&(与)Y，而不是Z=X||(或)Y，（就像我说的结论是两个条件同存的结论）所以支持Z必须使得X、Y同时为真。本题是讨论Y是否为真（关于如何支持参考上面的讨论）

要是削弱就更容易，因为X、Y、X&Y随便一个削弱（使其为假）都可以导致Z的削弱。

我觉得因为C是an earthquake，

Most modern histories of LACE>CyprusLACE> mention that an earthquake occurred near the island in A.D.365

也可能在其他时间发生其他的地震，所以没法确定一定加强结论，如果是他the only earthquake on that island 就是正确的了。不知说的对不，期待NN.

答叶子mm

(A) Bronze ceremonial drinking vessels that are often found in graves dating from years preceding and following A.D.365 were also found in several graves near Kourion.--既然是following.那么就应该是weaken 啊。。

还有found in graves dating from years preceding and following A.D.365 表明这些别的地方出土的器具通常在这一年的前后都有，因此可能是ad365年前后的任意一年。ad365年前后涵盖了整个时间轴。比如青铜剑吧，假如每个朝代的都一样，现在在河南安阳又出了一把，使说明不了什么问题的。除非我们认为无关也是削弱，否则认为它无关更好。

(D) Several small statues carved in styles current in Cyprus in the century between A.D.300 and 400 were found in Kourion--between 300 和400 之间，那么就有365以后的了。那么就应该也是weaken 的呀！~

不确定，因为只说是300-400年间的，那都是365年以前的也是有可能的，所以无关。

(E) Stone inscriptions in a form of the Greek alphabet that was definitely used in Cyprus after A.D.365 were found in Kourion.

在塞浦路斯用跟此地无关，同理a

班主mm要骂跟我联系。
