Test 10 · ★★★ · Trees

Why is it important to keep old forests as well as plant new trees?

Mova's choice: option 1 · The right answer: option 3 · wrong ✗ · What happens: be, keep · To what, where: old forests

This is test 10 · ★★★ of lesson 60 «Trees» of the biology 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.
