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 states that Sandie's "actual sister's name is Cassie" while distinguishing the doll (Lulu) as something Sandie only pretends is her little sister. This directly identifies the real sister without ambiguity.
