Worms, snails and slugs, sentence 5

Earthworms often come up to the surface after rain; one likely reason is that wet ground lets them travel across the surface without drying out, but scientists are not completely sure why they do it.

Who acts: Earthworms, wet ground, scientists · What happens: come up, be, let, travel, dry out, not be · To what, where: surface, one likely reason, earthworms, ground

This is a sentence of the lesson «Worms, snails and slugs» of the biology 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 (Earthworms, wet ground, scientists), 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 ×1, 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.
