We are asked to identify the one characteristic listed that the author does NOT explicitly discuss in the passage as part of the inquisitorial system.
(A) is incorrect because the author discusses it in lines 39-40 with the phrase "makes the trial less like a duel between two adversarial parties." Moreover, when we contrast the inquisitorial system discussed in this third paragraph with the adversarial system discussed in the second paragraph (especially lines 19-24), it becomes clear that the inquisitorial system is unique in that it is not based on conflict.
(B) is incorrect because the author discusses it in lines 31-38 as well as the fourth paragraph.
(C) is incorrect because the author discusses it in lines 41-43.
(D) is correct because the author never discusses that the defendant is in charge of his/her own defense under the inquisitorial system. There are no lines we can cite that show this without requiring undue assumptions.
(E) is incorrect because the author discusses it in lines 53-55.
Does that make sense? Please let us know if you have any other questions!
