What is everything made of?, sentence 4

Nobody has seen an atom with bare eyes, but careful experiments over two hundred years showed they are real, and special microscopes can now map single atoms.

Who acts: Nobody, careful experiments, atoms, special microscopes · What happens: see, show, be, map · To what, where: atom, single atoms · Speech: someone speaks here

This is a sentence of the lesson «What is everything made of?» 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 (Nobody, careful experiments, atoms, special microscopes), 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, R7-rel-agree ×2. 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.
