Light and shadows, sentence 2

When something blocks the light, it leaves a dark patch behind it in its own outline: a shadow, like your hand rabbit on the bedroom wall.

Who acts: something, Light · What happens: block, leave · To what, where: light, dark patch, patch

This is a sentence of the lesson «Light and shadows» of the physics course of Mova's primary school.

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 ×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.
