Pulleys, gears and big machines, sentence 12

An escalator is a long loop of steps pulled round by a motor and gears, and the steps flatten at the ends so you can step on and off.

Who acts: steps, you · What happens: be, pull round, flatten, step · To what, where: long loop, steps, ends

This is a sentence of the lesson «Pulleys, gears and big machines» 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 (steps, you), 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 ×2, R6-punct-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.
