Test 1 · ★★ · The Moon, the planets and the stars

If the Sun turned into a black hole of the same mass tomorrow, what would happen to the Earth's orbit?

Mova's choice: option 2 · The right answer: option 2 · right ✓ · Who acts: Sun, black hole · What happens: turn, happen · To what, where: black hole

This is test 1 · ★★ of lesson 14 «The Moon, the planets and the stars» of the myths 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.
