Test 9 · Why things fall: the apple and the pull of the Earth

Why does a higher wall mean a harder landing?

Mova's choice: option 2 · The right answer: option 4 · wrong ✗ · Who acts: higher wall · What happens: mean · To what, where: harder landing

This is test 9 of lesson 1 «Why things fall: the apple and the pull of the Earth» 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.
