Pressure tricks: pumps, tyres and vacuums, sentence 5
A vacuum cleaner's fan pushes air out, which lowers the pressure inside, so the outside air pushes in at the nozzle carrying dust.
Who acts: fan, air, outside air, nozzle · What happens: push out, lower, push in, carry · To what, where: air, pressure, dust
This is a sentence of the lesson «Pressure tricks: pumps, tyres and vacuums» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (fan, air, outside air, nozzle), what happens, when and where, as Mova's frames read it from the tree.
