Batteries, circuits and how electricity flows, sentence 8

Metals let electricity flow because they have loose electrons that can drift along; plastic, rubber and wood block it.

Who acts: Metals, electricity, loose electrons, plastic · What happens: let, flow, have, drift along, block · To what, where: electricity, loose electrons

This is a sentence of the lesson «Batteries, circuits and how electricity flows» 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 (Metals, electricity, loose electrons, plastic), 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): no change. 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.
