Famous discoveries told as stories, sentence 13

For centuries alchemists tried to turn lead into gold; they failed, because chemistry cannot change one element into another, but they invented many lab tools and methods.

Who acts: alchemists, chemistry · What happens: try, turn, fail, not change, invent · To what, where: lead, gold, one element, another, many lab tools

This is a sentence of the lesson «Famous discoveries told as stories» of the chemistry 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 (alchemists, chemistry), 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): R7-rel-agree ×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.
