Numerous Ancient Mayan cities have been discovered in the Yucatan peninsula in recent decades. The ruins lack any evidence of destruction by invading forces, internal revolts, or disease and appear simply to have been abandoned. Some archaeologists have theorized that the cities were abandoned due to a severe drought known to have occurred in the region between 800 and 1000 AD

Which of the following if true most strongly supports the archaeologists' theory?

A. Ample archaeological evidence of Mayan Peasant revolts and city-state warfare exists, but such events could never result in the permanent abandonment of cities.

B. No monumental inscriptions created after 900 AD have been found in these cities, but inscriptions dating before that time have been found in abundance.

C. studies of Yucatan Lake sediment cores provide conclusive evidence that a prolonged drought occurred in the region from 800 to 1000 AD

D. climatic studies have documented cycles of intermittent drought in the Yucatan peninsula dating from the present to at least 7000 years ago.

E. The Mayan City, Uxmal, was continuously inhabited from 500-1500 AD

B OR C...?

B. Since time of the abandonment of the cities now coincides with the drought period, it supports the theory that draught could be the reason leading to their abandonment.

The problem with C is that it does not provide the link between the draught and the abandonment. It only confirms that the draught actually happened.

个人认为选C

题干逻辑链：因为干旱所以城市被放弃，问support

按lawyer的分类，这道题属于support题的因果型结论，有一种加强的方法：显示因果关系的资料是准确

C选项符合这一种情况

而B选项，只是说明城市确实被放弃了，而没有对推理过程进行任何的加强。

非大神，发表一下观点，欢迎讨论，顺便问一下标准答案是？

B有加强，将干旱的时间和城市被遗弃的时间关联到了一起。

好像是唉~一开始的思路想错了

发现跟这道题很像

Excavation of the ancient city of Kourion on the island of Cyprus 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 AD 365.

Which of the following, if true, most strongly supports the archaeologists' hypothesis?
ABronze ceremonial drinking vessels that are often found in graves dating from years preceding and following AD 365 were also found in several graves near Kourion.  分析A选项
BNo coins minted after AD 365 were found in Kourion, but coins minted before that year were found in abundance.  分析B选项
CMost modern histories of Cyprus mention that an earthquake occurred near the island in AD 365.  分析C选项
DSeveral small statues carved in styles current in Cyprus in the century between AD 300 and 400 were found in Kourion.  分析D选项
EStone inscriptions in a form of the Greek alphabet that was definitely used in Cyprus after AD 365 were found in Kourion.  分析E选项
正确答案：B

我觉得是B吧，B项说没有900 AD 以后的铭文记录，进一步说明Ancient Mayan cities 被弃城了。而C项说从800到公元1000，该地区发生了长期的干旱，但干旱之后还是有可能再回来居住的，并不能说明Ancient Mayan cities 被遗弃了，削弱，所以选B项
