Final answer:
In 'To Kill A Mockingbird,' the ham outfit Scout wears unexpectedly protects her from serious harm during an attack by Bob Ewell, demonstrating its inadvertent yet life-saving advantage.
Step-by-step explanation:
In Harper Lee's novel To Kill A Mockingbird, the unexpected advantage provided by the ham outfit is significant for Scout's safety. During the climax of the story, Scout and Jem are attacked by Bob Ewell while walking home from a school event. Scout is wearing a cumbersome ham costume from the school play, which restricts her movement but ultimately protects her from Ewell's knife attack. The costume's bulkiness prevents the knife from causing Scout serious harm. Moreover, the attack is thwarted, and the children are saved by Boo Radley, who intervenes at the critical moment.
