The boy riding the donkey can either wear a yellow or a green shirt. Likewise, the two boys in the cart can either wear green or yellow.


Context: "One boy in a yellow shirt rides a donkey hitched to a cart carrying two boys in yellow along a road." Claim: "One boy in a green shirt rides a horse hitched to a cart carrying two boys in green along a road."
Considering the context, is the claim true, false, or unknown?
