Would the valid argument be: Most violinists at the NY Philharmonic know to play the violin. All people who know how to play violin are not exceptionally good at playing. Therefore, some (or all?) NY Philharmonic violinists are not exceptionally good at playing.

The title of this lesson literally contradicts the previous lesson. Would make more sense to say Exception or Implicit Exclusion
