Final answer:
Miss Caroline is taken aback because Scout learned to read and write in a non-traditional way, not because she can read and write, making the statement false.
Step-by-step explanation:
The statement "Miss Caroline is upset because Scout can read and write." is false.
This scenario takes place in the novel To Kill a Mockingbird, where Scout's teacher, Miss Caroline, is actually taken aback and somewhat disapproving, not because she can read and write, but because Scout has learned to do so in a non-traditional way before the teaching curriculum intended it.
Miss Caroline's educational philosophy does not align with how Scout was informally taught at home, which is why her reaction may be misinterpreted as upset or anger.
