public class SiblingUproar extends ExampleFD
This is quite difficult logic puzzle to be modeled and solved by CP.
Mrs. Wheatley returned home from her job to find the household in a turmoil of arguments. Each of her five teenagers (three boys named Bryan, Russell, and Stuart, and two girls named Nina and Paula) had gotten angry at one of his or her siblings for a different reason (finished cereal, let dog in room, used up hot water, failed to return rollerblades, and hogged television) and had decided to retaliate in a different way (knocked over chess game, let gerbil out of cage, hung up on friend, removed light bulbs, and hid violin).
After a few futile minutes of trying to sort out blame, Mrs. Wheatley called a halt to the arguments by declaring everyone equally guilty and giving each a different chore around the house as that evening's punishment (cleaning the attic, basement, or garage, or washing the Venetian blinds or windows). Can you discover, for each child, the sibling he or she was initially angry at, the reason for the anger, the retaliatory measure he or she took, and the chore meted out to each child?
1. No one was originally angry at the sibling who was angry at him or her.
2. The boy who was angry at the sibling who used up all the hot water taking a shower retaliated against him or her by removing all the light bulbs from his or her room; the child who was angry at this boy was later punished by being sent to sweep the basement.
3. The five siblings are: Paula, the person who was angry at Paula, the person who was angry because a sibling was hogging the television, the child who was told to straighten the attic, and a child to didn't remove a sibling's light bulbs or hide a sibling's violin.
4. The child who was angry at Stuart was punished by being told to wash the Venetian blinds.
5. Russell was punished by being sent to clean out a section of the garage.
6. The child who let the dog in a sibling's room didn't retaliate against another sibling by knocking over a chess game that he or she was playing.
7. The child who was hogging the television was angry at a sibling who wasn't punished by being told to straighten up the attic or wash the windows.
8. In retaliation, one person hid the violin belonging to the person who was angry at Paula.
9. Bryan and the person who was punished by being told to wash the windows are, in same order, the child who was angry at the sibling who didn't return the rollerblades and the one who retaliated against a sibling by knocking over a chess game in progress.
10. Stuart and the person who was angry at Nina are, in some order, the child who was angry at the person who finished the best cereal in the house and the one who retaliated against a sibling by hanging up on his or her best friend.
Determine: Sibling - Angry at - Reason - Retaliation - Chore
