Four people being at a skate park doesn't reveal any information about other people also being present and it can't be inferred that the park is crowded with people.


Context: "At a skate park one man skateboards, one rides a scooter and 2 men record the skateboarder from below and above him." Claim: "The skate park is crowded with people."
Considering the context, is the claim true, false, or unknown?
