Question: Given the following context:  After the Wicked Witch of the West is melted by a bucket of water, and Dorothy is sent back to her world, Glinda, the Good Witch of the South, decides to revive the Wicked Witch and remove her powers by storing them in a magic broom. Glinda then gives the magical broom to Dorothy's friends, Tin Woodman, Cowardly Lion, and Scarecrow, and they become the guardians of the broom. Evilene, the Wicked Witch, conspires with her Flying Monkeys to retrieve her broom. However, a friendly little monkey named Ozzy forgets to close the gate of the castle and a battle ensues between the flying monkeys and the 'Bums of Oz.' Evilene retrieves her broom and repels the Champions of Oz from the castle. She then punishes Ozzy's father, transforming him into a chicken. Angered by the witch's spell on his father, Ozzy steals the broom from Evilene and runs away from the palace. Ozzy reaches Glinda to find she has been paralyzed by accidentally drinking a magic potion created by her niece Gabby, who is unable to create an antidote without a vital ingredient based on wood. Gabby and Ozzy set off to find the Champions of Oz. They are pursued by the other Flying Monkeys. They soon find Cowardly Lion, who is out of sorts due to the witch's spell, but with some effort they guide him to the north town, where they find the Tin Woodman, who is extremely depressed by the spell. The spell-raged Lion smashes the Tin Man to bits, but calms down when Ozzy accidentally hits him with the magic broom. Ozzy, Gaby, and the Cowardly Lion take the Tin Man's parts to the Library of Oz where (due to the spell) Scarecrow is obsessively reading books in an effort to become more intelligent. He quickly repairs Tin with the help from a clue. However, the group is attacked by the Flying Monkeys, and in the chaos Ozzy cures Scarecrow of the spell's effects, but they are unable to save Gabby from being whisked away by the Flying Monkeys.  answer the following question:  What is the name of the person who repairs Tin?
Answer:
Scarecrow
