Test 5 · ★ · Molecules: when atoms join up

How does a two-metre DNA molecule fit inside a tiny cell?

Mova's choice: option 1 · The right answer: option 2 · wrong ✗ · What happens: do, fit · To what, where: metre DNA molecule, tiny cell

This is test 5 · ★ of lesson 3 «Molecules: when atoms join up» 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.
