When reading this passage, I figured out the key question would be finding why/how the leading question yield the unreliable testimony of the eyewitness.
And thru reading the 2nd paragraph, I figured out because of our memory system which tends to process the new data, if not significantly conflicting, as a reinforcement of the corresponding aspect of the existing data or filling the gap.
Therefore, reading this as a problem-solution structure, for eradicating the problem of unreliable witness due to the leading question prior to the courtroom interrogation, we should check/ confirm the new data which have been interacted before the trial.
Via this reasoning process, I could easily accessed to the correct answer of E on Quesition #21
But when I was solving this question for the first time, I randomly added my own assumption of referring the "unreliable" testimony to be imbalanced or somewhat biased one.. Therefore, I checked (D) as my 1st time answer cuz I believed that the both sides of lawyers could function as "check and balance" and prevent from yielding biases..
When I could not have spent enough time reading the passage, I automatically add my own assumptions, which are usually invalid and check the wrong answers.. (I'm the one who is adulterated by the leading question of LSAT :p)
After my long excuses.. I want to ask you if the question 21 could be solved with a scope in mind as of "increase the justice system's ability" and the time scope of "prior to appearance of the witness"
: Using the time scope, D and E are only left
And because D has nothing to do with Justice system's ability but it's the solution only between of lawyers,
D could be deleted in my opinion.
What do you think about my solution of Q21?? is it too weird??
