If 4 lengths of rope hold a load in a set of pulleys, you pull with about a quarter of the force, but you must pull 4 metres of rope to lift the load 1 metre.

Who acts: 4 lengths, you · What happens: hold, pull, lift · To what, where: load, set, 4 metres

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, R8-pos-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.
