Test 9 · ★★★ · How we know: measuring the sky

If Earth went round the Sun faster at the same distance, what would that tell us about the Sun?

Mova's choice: option 3 · The right answer: option 4 · wrong ✗ · Who acts: Earth · What happens: go, tell · To what, where: Sun, us · Speech: someone speaks here

This is test 9 · ★★★ of lesson 28 «How we know: measuring the sky» of the space 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.
