问题单项选择题

一块石头被石匠修整后，曝露于自然环境中时，一层泥土和其他的矿物便逐渐地开始在刚修整过的石头表面聚集。这层泥土和矿物被称作岩石覆盖层。在一个安第斯纪念碑的石头覆盖层下面，发现了被埋藏一千多年的有机物质。因为那些有机物质肯定是在石头被修理后不久就生长到它上面的，也就是说，那个纪念碑是在1492年欧洲人到达美洲之前很早建造的。下面哪一项，如果正确，能最严重地削弱上述论述( )

A．岩石覆盖层自身就含有有机物质

B．在安第斯，1492年前后重新使用古人修理过的石头的现象非常普遍

C．安第斯纪念碑与在西亚古代遗址发现的纪念碑极为相似

D．最早的关于安第斯纪念碑的书面资料始于1778年

答案

参考答案：B

解析：有机物质在岩石覆盖层“下面”，与覆盖层是否含有机物质无关，A淘汰；B指出虽然有机物质的年代长，但是建造纪念碑的年代还是最早在1492年前后，削弱了题干论述；C、D为无关选项。
