T-4-37:GWD-13-26:
The passage is primarily concerned with

A.    reassessing a phenomenon in light of new findings

B.    assessing the relative importance of two factors underlying a phenomenon

C.    examining the assumptions underlying an interpretation of a phenomenon

D.    expanding on an explanation of a phenomenon

E.     contrasting two methods for evaluating a phenomenon


为什么选D，我选了B，定位不出而且回看原文没有发现依据选D。
还有首段，L9开始那个factors that....在整个句子中做什么成分？是considering 1.that...and 2. factors that....吗？如果这样，根据句子改错原理前后不对称？期待大家讨论
