求助一道逻辑题！！

Most jurors will be more inclined to reach a verdict favorable to one side if that side's case is based primarily on eyewitness testimony rather than on physical evidence backed by expert scientific testimony. Surprisingly, studies involving jurors in mock trials have found that this tendency survives even for those jurors who understand that eyewitness testimony is generally less reliable than is physical evidence backed by expert testimony.
Which of the following, if true, would most help to explain the surprising phenomenon described above?
(A) Jurors in mock trials usually spend less time deliberating and worrying about reaching the right verdict than do jurors in actual trials.
(B) Because expert testimony regarding physical evidence presented at trial is almost invariably given by witnesses testifying for one side or the other, many jurors regard such witnesses as biased.
(C) The credibility that a particular juror will assign to a particular eyewitness will be profoundly influenced by personal characteristics of the eyewitness including age.
(D) Even jurors who understand that eyewitnesses tend to be less reliable than physical evidence incorrectly believe they are better than the average juror at telling when an eyewitness’s testimony is reliable.
(E) The more complex the physical evidence presented at trial is, the less it will influence the jurors in reaching their verdict.

答案选D，我做题的时候选的也是D，但我觉得如果没有更好的D的话，B也能说的通。
求助各位，这个B是错在哪里了呀？
谢谢！！

这道题是要解释为什么相比于physical evidence，法官会更偏向于eyewitness testimony，B项说法官认为physical evidence是biased，并没有解释为什么更偏向eyewitness testimony。
D项：即使是知道eyewitness testimony不可信的法官也会犯错，解释了这种偏向。

这道题属于比较典型的A vs B的比较题。如果把题干的意思抽象出来就是大部分juror是喜欢eye over phys的。这个结论在他们知道eye evidence不可靠的情况下依然成立。
比如eye (100) > Physical (70), 他们知道eye不可靠，真实数字比100小，比如内心默认80， 但是还是做出了eye （80） > phy （70）的结论。
哪个选项能帮助解释这个：
(B) Because expert testimony regarding physical evidence presented at trial is almost invariably given by witnesses testifying for one side or the other, many jurors regard such witnesses as biased.
B选项说的是Phy同样也是有问题的，也就是把phy 70的可信度往下降，确实能在某种角度上解释这个现象。

(D) Even jurors who understand that eyewitnesses tend to be less reliable than physical evidence incorrectly believe they are better than the average juror at telling when an eyewitness’s testimony is reliable.
D选项说的是juror（错误的认为）他们能分辨出eye的水分有多少，也就是这些juror相信他们看到的100>70就真的是100>70

BD的差别在于考察A>B的时候，如果出现了A扰动，GMAT的答案比较全面的是法分析A与B两个变量的扰动，如果没有这个选项，更倾向于解释A的扰动，干扰选项一般有解释单独解释B的扰动，这个一般很难解释AB直接的difference被排除。
PS: 其实这个逻辑是GMAT的逻辑，很难经得起quantitative 分析的考量，真的就是做做题考试而已。
