Test 2 · ★★ · How stars live

If gravity in a star suddenly got much weaker than the push of its hot gas, what would happen?

Mova's choice: option 1 · The right answer: option 2 · wrong ✗ · Who acts: gravity, hot gas · What happens: get, happen, push

This is test 2 · ★★ of lesson 18 «How stars live» 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.
