Festival Lineup
A music festival was held last week for 4 days, with
1 show each night at a different time between 8: 30
and 8: 50. Each of the 4 performers played their
favorite instrument, for 1 night only.
Ted did not play the violin. The Thursday show
started at 8: 30, but Brett did not perform. Jason,
who doesn’t play the flute, starred in a time slot that
was 5 minutes later than the person who played the
piano. The Sunday show featured a flute. The 8: 40
show was not the Friday show. Brett did not play the
Saturday show. Dan played on Friday, but did not
play the piano. The 8: 50 show featured a guitar.
Who played what and when?
Russian Roulette
After sending competing assassins to each
other’s castles, the evil king and the evil
queen decide to settle their differences face
to face. The king proposes a game of Russian
roulette, and the queen accepts. The king
then places 2 bullets in 2 consecutive chambers of the 6-chamber revolver and gives the
cylinder a spin. He points the gun at himself
and pulls the trigger … click! He hands the
gun to the queen and says, “You can give it
another spin if you want, or you can just pull
the trigger.” What does the queen’s sage
advise her to do?
