Ethics WTF Questions required, correct, getting, returns, through

Muddahudda

So I'm doing all the ethics questions in the required readings. Blew through the first 40 non-item set questions getting all but two correct.

The item set questions are obviously much harder. Some of the interesting ones so far.

#52 Now you have to report all gifts even if less than $100? Interesting.
#55 Both B and C look pretty good to me.
#59 So Vinken is not in violation of showing potentional clients simulated returns. Why is that not a violation?
#60 Both Vinken and Khadri only keep records for five years. Seven years is the RECOMMENDED time so I suppose they aren't in violation. Tricky.

This one takes the cake.

#64 A firm is notified by client that they atually underperformed the benchmark despite saying they overperformed. Khadri researches, see's they're correct and sends him a letter with an apology and corrected results. He blaims the discpancy on a human typographical error.

The answer to which vilation Khadri is least likely to have made
A. Misconduct
B. Misrepresentation
C. Performance Presentation

Answer is C.

FVCK me sideways with a lunchbox. How is he guilty of misconduct when it implies that it was a honest error. The answer says she knowingly misrepresented peformance. AND it says that she's least likely to violate performance presentation because she provided the correct letter to the client. I don't get this one at all.
