premise: Three young boys sitting outside are looking at something obscured between them.
hypothesis: Boys are looking at a bug on the ground
explanation_1: There is nothing that implies the something the boys look at is anything in particular, including a bug. That they look at something between them does not imply that thing is located anywhere in particular, such as on the ground.
