【单选题】通过分析样品所含的碳元素,取自宾西法尼亚州的一个岩洞地面上的样品的日期得以确定。样品所标定的日期与人类的活动相联系,在时间上形成一个从现在到过去的连续的系列。该系列与样品取自地面的深度相关联,最古老和最深处的样品被标明是两万年前的遗物,误差在上下2000年之间。怀疑者认为该日期太早,与公认的人类移居南美洲的时间木符,提议该样品可能会被附近煤沉积层中渗出的地下水中溶解的碳所污染。下面哪一个理由如果正...
A.
不可能会有渗出的地下水造成的污染仅影响到那个地方较深处的样品而没有影响到最上层的样品。

并不是每一种碳元素标定日期的方法都会被科学家普遍接受。
C.
没有迹象表明,人们在最深层可能沉积F的时候在使用煤作燃料。
D.
该系列中没有样品,当用碳元素标定日期法对这些样品的日期进行再次检测时,没有样品标定的日期比它上面的一层中的样品早。
