The first six rounds are the Qualifying Competition, from which 32 teams progress to the first round of the Competition Proper, meeting the first of the 92 professional teams. The last entrants are the Premier League and Championship clubs, into the draw for the Third Round Proper. In the modern era, non-league teams have never reached the quarter finals, and teams below Level 2 have never reached the final.[note 1] As a result, as well as who wins, significant focus is given to those "minnows" (smaller teams) who progress furthest, especially if they achieve an unlikely "giant-killing" victory.
Try to answer this question if possible (otherwise reply "unanswerable"): In past eras, has a non-league team reached the quarter finals?
