<human>:  Why did the Titanic sink?
<bot>: The Titanic sank because it hit an iceberg. The ship was too big to turn around, and it could not slow down enough to avoid the iceberg. The ship was made of wood, and the collision caused it to split into two parts. The bow of the ship was crushed, and the stern remained intact. The water in the ship quickly filled the space between the two halves of the ship. This caused the ship to sink.
