premise: Two soldiers stand next to a truck holding packages of games, puzzles and building blocks. hypothesis: So many children are gathered waiting for the military men to start handing out toys from their donation trucks.
contradiction: No idea who else is there (many children), or why (waiting). No idea why they are holding packages, or what they intend to do with them (handing out). No idea what the truck is for, or if there are  more than one (donation trucks.).
