That's Puzzling

4. When Tori and Jordan were going through the
trunk in the attic, they found a number of puzzles
and asked their grandma about them. She told
them that her grandparents used to leave puzzles
around the house for her mom and her uncle.
Whoever could solve all the puzzles first could
choose a chore that they did not have to do that
day, such as washing the dishes or folding the
laundry. Your great-grandmother loved to get out
of chores, so she was very good at the puzzles.
