<!-- .vintro -->
**Who acts:** submarine · **What happens:** fill, sink, blow out, rise · **To what, where:** tanks

<!-- .vabout -->
This is a sentence of the lesson «Floating in the real world: ice, submarines and balloons» 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 (submarine), what happens, when and where, as Mova's frames read it from the tree.
