Black holes, sentence 0
A black hole is not a hole and not a cosmic vacuum cleaner: it is a huge amount of mass squeezed into a tiny space, so its gravity is so strong that not even light can get out.
Who acts: black hole, hole, gravity, light · What happens: not be, be, squeeze, get out · To what, where: hole, huge amount, tiny space
This is a sentence of the lesson «Black holes» of the space 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 (black hole, hole, gravity, light), 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.
