This is exam question 1 of lesson 41 «Alice's fall and her sizes: falling, the centre of the Earth, giants and tiny people» of the physics course of Mova's primary school, asked in stiff, formal language. 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/41-alice-s-fall-and-sizes-falling-the-centre-of-the-earth-giants-and-tiny-people/#e1).
