Test 2 · Separating mixtures

What would happen if you tried to filter salt out of salty water with a coffee filter?

Mova's choice: option 2 · The right answer: option 3 · wrong ✗ · Who acts: you · What happens: happen, try, filter · To what, where: salt, salty water

This is test 2 of lesson 8 «Separating mixtures» of the chemistry 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.
