The stomach churns food with strong hydrochloric acid and enzymes that break down proteins, and the acid kills many germs; a layer of mucus stops it digesting itself.

Who acts: stomach, enzymes, acid, layer · What happens: churn, break down, kill, stop, digest · To what, where: food, proteins, many germs

This is a sentence of the lesson «Digestion: the journey of a sandwich» of the biology 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 (stomach, enzymes, acid, layer), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R5-strong ×1, R6-punct-agree ×1, R7-rel-agree ×1. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
