Which fact is true regarding Kafka's sister?

• A. She has a twin
• B. She is adopted
• C. She lives abroad
• D. She is the youngest

Answer: (B)

In this story, the important detail about Kafka’s sister is that she is adopted. The narrative treats her as not being a biological child of the father, which is why adoption is the only fact that fits with what is revealed about their family background. This detail ties into the book’s broader interest in unconventional family ties and questions of belonging, reflecting how identity can be shaped by more than just blood.

The other options aren’t supported by what the text shows. There’s no indication that she is a twin, lives abroad, or is the youngest, so those possibilities don’t fit the evidence the story provides.
