The person either climbs a pole or falls off the roof.  The location may be grass by a yellow house so it is not absolutely contradictory.


Context: "A dark-haired man in jeans and a blue checkered shirt climbs a pole along side a yellow house and approaches a clay-tiled roof." Claim: "A worker falls off the roof, onto the grass below."
Considering the context, is the claim true, false, or unknown?
