# Test 9 · The Sun, our star

<!-- .ven lang=en -->
Which is surprising about the Sun's temperatures?

<!-- .vintro -->
**Mova's choice:** option 1 · **The right answer:** option 4 · wrong ✗ · **What happens:** surprise

<!-- .vabout -->
This is test 9 of lesson 1 «The Sun, our star» 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](https://md.mova.elamur.ai/free/en/school-run/space/1-the-sun-our-star/#t9).
