**Problem 1:** There are
three piles of stones: one with 10 stones, one with 15 stones, and one with 20
stones. At each turn, a player can choose one of the piles and divide it into
two smaller piles. The loser is the player who cannot do this. Who will win,
and how?

**Problem 2:**** **Given two
parallel lines and a fixed point, draw the straight line, which goes through
the given point and is parallel to those two lines. Use ruler only. No compass
is allowed!
