Your friend says: "Air is nothing, you can't push against it." What does the syringe show?

<!-- .vintro -->
**Mova's choice:** option 3 · **The right answer:** option 2 · wrong ✗ · **Who acts:** friend, Air, you · **What happens:** say, be, not push, do · **To what, where:** nothing, syringe show · **Speech:** someone speaks here

<!-- .vabout -->
This is test 1 of lesson 4 «Solids, liquids and gases» of the chemistry course of Mova's primary school. The page gives the question's syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause, then the 4 options as the student saw them, each with its tree and pragmatics. Every text is parsed by Mova itself. How the student answered it, with the score of every option and why: [the test at school](https://md.mova.elamur.ai/free/en/school-run/chemistry/4-solids-liquids-and-gases/#t1).
