一道LSAT的逻辑题，希望大家讨论

Two paleontologists, Dr Tyson and Dr. Rees, disagree over the interpretation of certain footprints that were left among other footprints in hardened volcanic ash at site G. Dr. Tyson claims they are clearly early hominid footprints since they show human characteristics: a squarish heel and a big toe immediately adjacent to the next toe. However, since the footprints indicate that if hominids made those prints they would have had to walk in an unexpected cross-stepping manner, by placing the left foot to the right of the right foot. Dr. Rees rejects Dr. Tyson's conclusion.

7. The disagreement between the two paleontologists is over which one of the following?

(A) the relative significance of various aspects of the evidence

(B) the assumption that early hominid footprints are distinguishable from other footprints

(C) the possibility of using the evidence of footprints to determine the gait of the creature that made those footprints

(D) the assumption that evidence from one paleontologic site is enough to support a conclusion

(E) the likelihood that early hominids would have walked upright on two feet

答案：A，我选了C

我觉得c更直接。A 感觉非常remote.
请大家帮我解释解释

楼主我选A
R反驳T的结论，T的结论是这些脚印是原始人的脚印，得出这些结论的证据就是脚印有原始人的特征。而要反驳T的结论最直接的就是驳evidence的特征不是原始人的特征，或者即使是原始人的特征也不能证明就是原始人的脚印。A恰好体现的就是这一点。而C已经就着evidence走到了去研究步态了，走远了。
浅见
peace out

(A) the relative significance of various aspects of the evidence
T是通过脚印的形状来判断的，而R是通过脚印的步伐来反驳T的。都是“脚印”
(B) the assumption that early hominid footprints are distinguishable from other footprints
(C) the possibility of using the evidence of footprints to determine the gait of the creature that made those footprints
(D) the assumption that evidence from one paleontologic site is enough to support a conclusion（A）
(E) the likelihood that early hominids would have walked upright on two feet
