Hi tizwu,

Y must be with either H or G because of the the conditional chain when either H isn't with Y or G isn't with W: either one forces the F with W and L with Z, which means X and Y must go with H or G. If L isn't with Z, then F is, meaning G then would go with W and H would have to go with Y, leaving L only able to be with X. There is no way to put L or F with Y and not also force H into that spot, thus breaking the rules.

Hope this clears things up!
