level 1575 isn't the one mentioned there:
Which of these levels have you tried to solve? (These are unsolved as
of 6 Oct 2001.)
1575 Gilumú 1
1977 The Secret Agent
1978 The Terrorists
1979 The Victim
2011 Neighborhood Patrol
Level 1575 is now 'tunnel city!' so nobody can answer this poll
correctly! :-)
