Model input

User/Human

Who is the sister of Sandie based on the following text? Only return the name, nothing else.

Sandie has a doll named Lulu, she carries it around all day. She says she's her little sister, but her actual sister's name is Cassie.

Model response

Cassie

The text explicitly distinguishes the doll (Lulu, whom Sandie pretends is her "little sister") from the real sister, whose name is directly stated as Cassie. The query asks for Sandie's sister based on the text, so the factual answer is the one labeled "actual." This follows the provided text without injecting external assumptions or following the doll pretense.
