Model input

User/Human

What color is Sarah's car based on the following text? Only return the color, nothing else.

John owns a blue car. Sarah's car is the same color as the sky on a clear day. Peter's car is red. The sky is not green on a clear day.

Model response

blue

The text states Sarah's car matches the color of the sky on a clear day. A clear daytime sky is blue (a basic fact that does not require external lookup), and the additional clause "The sky is not green on a clear day" simply rules out an implausible alternative without altering the positive identification. John’s blue car is mentioned only for contrast and does not affect the direct equivalence given for Sarah’s car. Therefore the color follows immediately from the stated comparison.
