请教CXD-assmuption-16 的题目

WO爱逍遥

16,Prolonged and unseasonable frosts produce frost rings in deciduous trees, which grow in moderate climats. Frost rings do not appear in any of the fossilized decidusous trees that have been found in Antarctica. Hence, it is unlikely that such frosts occurred in Antarctica at the time the fossilized trees lived.

Assumption:

C.The process of fossilization does not completely obscure frost rings in deciduous trees.

答案是C 可以理解

为什么B错

B Deciduous trees are more likely to bear frost rings than other tree varieties

题目 明明  把落叶树 换成了the fossilized trees
明显以偏盖全     B  不对嘛

LZ理解错题目咯~~

题意：持续的并且不合季节的霜冻会在落叶树上产生霜环，落叶树是生长在温和气候下。在南极洲发现的落叶树化石上并没有霜环。因此，在南美洲生长落叶树的时期里有这种霜冻的可能性不大。

问以上推论的假设

很明显B选项无关啊，这推理链不涉及其他树
