OE
This sentence is difficult because the word “impressed” is used to refer to making an impression in a negative way. The defendant did not make a positive impression; rather, the sentence suggests that she came across as not as naïve as she pretended to be. “Disingenuous” means precisely that and one meaning of “artful” is deceptive. The sentence does not suggest that the woman was “innocent,” and while she might have been “accomplished,” that’s not how the jurors thought of her actions. “Guileless” is a trap since it is a synonym of both ingenuous and artless, all three of which mean innocent and without deception; this meaning, however, is the opposite of what the blank requires. Finally, “culpable” means guilty and is an attractive trap, but goes further than the clues in the sentence; the woman was not naïve, but she was not necessarily guilty.
