Why can the Sun and the Moon look the same size in the sky?
Mova's choice: option 3 · The right answer: option 2 · wrong ✗ · Who acts: Sun · What happens: look · To what, where: same size, sky
This is test 10 of lesson 39 «Day and night, and the Moon's faces» 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.
