lol my mate says rockets can't work in space cos there's no air to push on. is he right?

<!-- .vintro -->
**Mova's choice:** option 4 · **The right answer:** option 4 · right ✓ · **Who acts:** mate, rockets, air · **What happens:** say, not work, be, push on · **Speech:** someone speaks here

<!-- .vabout -->
This is test 1 · ★★★ of lesson 38 «Rockets, record speeds and motion everywhere» of the physics 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/physics/38-rockets-record-speeds-and-motion-everywhere/#t1).
