Test 3 · Wind and the air around the Earth

If the ozone layer grew much thinner, what would happen?

Mova's choice: option 1 · The right answer: option 3 · wrong ✗ · Who acts: ozone layer · What happens: grow, happen

This is test 3 of lesson 69 «Wind and the air around the Earth» of the world 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.
