Preference "of" versus preference "to"

Hi, Had the question stem substituted the word "of" for the word "to", i.e. "According to the fourth paragraph of the passage, what specifically does Bentham characterize as preference [TO] ignorance of knowledge," it would've, as the result of this word substitution ("to" for "of") been asking for what Bentham would like to establish as a rule of evidence: " the non-exclusion principle," or specifically allowing the jury the determine the character of the otherwise would've been excluded evidence. Correct? Thank You Mazen
